What even is the point he's trying to make? They are eggs, those are what eggs are. What property is he supposing eggs should have which makes these eggs not eggs?
It makes sense to me. I think of eggs as being external to the body and already fertilized, but ova are internal to the body and aren't fertilized. Granted this doesn't really work when you're talking about fish or frogs, because they basically expel their ova before fertilization. But since mammals don't have eggs (except for monotremes) it seems like a distinction worth making.
I remember in 8th grade they were showing us a video for sex ed, and the video was so outdated that it said there were around 4 billion people in the world. This was only like 4 years ago (keep in mind the human race hit 5 billion in 1987). I think this is a good example of how concerning neglected sex ed is, and how outdated a lot of the information can be. Good thing SciShow it here to help.
I also go to a catholic school and we don’t get this, we had “theology of the body” and a chapter on the human reproductive system in 4th grade science class but we skipped over it. In 10th grade biology we talked about the reproductive system of single cell and multi cell organisms but not on the human body. We have an anatomy class for 12th grade but I don’t take it so idk if it covers it or not.
Even as a teen I found it strange that people took the words "average length of menstrual cycle" and made it into "you are abnormal if it's not 28 days." Apparently all the worksheet practice figuring averages didn't transfer well. Thanks again to Sci Show for reminding us what words mean. :)
Yup. I always had a cycle of 35-37 days as a teenager, and it never bothered me because that’s just on the long end of the average range. But I was often told by peers that was weird. They all just couldn’t comprehend that some people end up flat-chested and stay that way, or that they all got their periods in the early end of average and were often told incorrectly by their parents that it was a sign of disease to get it later than 11 years old when the average is 12, and my perfectly healthy, much older sister who was a mom at that point didn’t get hers until she was 14. The degree to which misconceptions can fuel preteen-early teen bullying is enormous.
Humans are really bad at math and the concept of an average, so I wouldn't be surprised if after the first primary source was published, whoever was responsible for packing it into textbooks must think you must be average or abnormal.
This is why we didn't generally use the term "fact" but theories. That doesn't mean they are wrong... they just keep it open as we never know if we missed something.
I mean science is literally just an attempt at understanding the world through a specific kind of research. It’s not the be all and end all. It’s still a very human process where mistakes are made because often in reality you can’t test in a “vacuum”. Imo a lot of people characterize “science” as some all knowing single entity. The reality is that there’s a lot of researchers and a lot of papers and often their results are incredibly conflicting!
I mean, how much do you know about penises really? I'd be surprised if neither you nor a friend of your's didn't have gaps of knowledge when it comes to reproductive organs you don't have first hand experience with. (For the record I did know but only after helping a friend in highschool.)
I was always told the cycle was so close to the lunar cycle that most women could just remember the moon phase of their period, then use the moon phases already on calendars without marking stuff, except in puberty etc., which is exactly when someone would bother with an app, thus filling that study with more unusual periods than in the actual population. But that might all still just be a myth.
@@johngypsydoe862 Yeah "most women" would expect to at least see a little drift, like when you see the indicator lights flashing on two cars, for a while they'll appear to synchronise, flashing at the same time, but then move out of phase til they look like they're taking turns to flash etc. So, the lunar month length is 29 and between around 7 and 19 hours (as it's not a perfectly circular orbit) so even a cycle length of 28 days would progress through the lunar cycle backwards, being one day earlier each cycle. But cycle length is just how genes respond to blood chemistry, so changes in diet, hydration levels, sleep and exercise, other hormones from things like stress, all come into play. The more these follow fixed patterns, the more you'd expect various body clock cycles to too.
"2-7 days you're on your period" I feel mf scammed, I've had 10-12 day periods since the first time I got it. Now I have the implant and thr average is two weeks of bleeding. Being female is a scam and I would like a refund.
Im actually legit in tears at the wording in this video. Like ding dang, y'all sure as heck know what you're doing 😩 the level of inclusive language used makes this nonbinary heart so goshdanged happy. Please never stop being awesome
As a woman without a uterus over on the other side of this Im also so so glad for the language! Just calling people with uteruses "women" isnt Just excluding the people with uteruses who arent women, such as your majestic nb self, but also excludes people like me, who dont have a uterus, but are still very very much women!
Here's some news. You CAN get pregnant when you're already pregnant. My twin brother and I are fraternal twins with about 3.5 weeks between our conceptions.
Furthermore my youngest was a 'stealth' baby. I had my cycle the whole time I was pregnant. I think he implanted to the far right of my uterus while my left ovary never got the memo.
How do you know that? As opposed to you both being conceived during the same window of conception? Was your mother only diagnosed with one pregnancy at some time during the first 3.5 weeks?
Actually had sex ed and learned from it too. And had youths come and talk about their embarrassing experiences and answer all stupid questions we had, lesser age difference makes them more relatable. And still there were some stuff to learn from those british channel 4 edutainment shows and some Web comics, also they were just funny
Yeah, myth #2...most women already know this. My period always changes based on a lot of things, stress, medication, nutrition levels. Surgery! I lost my period for 2 months after surgery.
Yep. And while it's not statistically proven that cycles "sync up" I have seen and experienced so much anecdotal evidence that our hormones interact that it would be absurd to dismiss that. There ARE many triggering/altering factors. But the nuance of those interactions makes it really iffy for science to pin down.
Remember, the myth that ovulation occurs on day 14 of a woman's cycle, is where this joke came from: "What do you call a couple who uses the Rhythm Method for birth control?" "PARENTS!"
Thank you, Stefan Chin, for presenting this is a grown up, matter of fact manner without it being dry. Good job to all who took part in creating this Sci Show episode.
I dated a woman who had an ablation surgery to stop her periods. She literally would ovulate constantly and bleed nearly continuously for months on end. One full cycle every few days.
Wait, are you saying this was AFTER the surgery and that she was normal before it, or are you saying that she had the surgery because this was what she was like naturally? Because it sounds like the effect of the surgery was the exact opposite of what was desired.
They might not be so lucky, I only have 3 (and one or to days of spotting), but 1 or 2 are super painful to the point where I've had to change my pain medication to a stronger one and it still doesn't fully stop the pain. But when I was younger I had 7 days (counting spotting, I can't remember how many of those were spotting) and no pain at all.
Hey guys, where'd the close captions go? I'm hard of hearing and of allllll the videos I don't want to blast at full volume and wake my very young children up, this is it.
i grew up in a very religious household and walked out in protest when my school tried to do a class on sex ed. now that i've broken free and can think for myself... i regret that decision. anyway, trans rights
Could we get a video on PCOS and/or Endometriosis if it hasn't been done already? 😮 I have PCOS myself but there aren't too many videos on the subject.
Yeah, the thing with the can’t get pregnant on period is why a relative of mine couldn’t have kids. But turned out, she just ovulated really early and couldn’t have kids unless she had sex on her period
One study found 52% of sexually active women had intact hymens. Not to mention they can heal and don’t always “tear” the first time a woman has sex. The idea that “sex is supposed to hurt the first time” is horrible and dangerous.
"Some people had variable cycles, where the length was somewhat unpredictable..." THANK YOU. My body NEVER obeys human-contrived schedules - and this can lead to ruined plans aplenty. (When one's period is as unpredictably nasty as mine are...)
3:17 I feel like their conclusions are biased tbh, cause most of the people I know that have regular periods don't use period tracking apps, most of the time the people using these apps are women with irregular periods
Surely the biggest thing we still get wrong is treating both the menstrual and broader reproductive cycles as something dirty and taboo, to be avoided in everyday conversation. Which is what makes this video a breath of fresh air: the fact SciShow is not afraid to discuss something that is so often missing from public debates about issues related to sexuality.
Human reproduction was one of the most fascinating subjects I ever took in med school and even if I hadn't taken it then also took it at my first University and still found it to be extremely fascinating. It's like the big bang so many things need to come together in one small window of time to make a human being. It's a wonder that we can reproduce at all!
3:39 "Sperm can survive for days after sex.." I wonder how many teenagers are having a panic attack during the next minute or two of you explaining this one..🤔
Lol, never had that problem, didn't have sex until I was 20. Oh and sex is overrated for what's at risk. 30 seconds of pleasure isn't worth 18 years of slavery. No thanks
Nope, like Inception, there's always another layer of understanding. When I went in for infertility consult (many moons and sad-periods ago), turns out they had discovered an entirely new major *hormone* (anti-Mullerian hormone, AMH, fun stuff) in the 12-15yrs or so between then and when I learned this stuff in school & from my first GYN.
I think a lot of it has to do with ethics. Society in general isn't okay with growing human embryos in petri dishes for scientific research. Nor is society okay with taking a deep look into the reproductive systems of humans, particularly women's. It's hotly politicized, all around the world. That kind of controversial research is exactly what is needed to further our understanding of human reproduction in major ways.
I love how they followed that up with, "Wellllll, so far, we haven't proven this, so as far as we know, that is actually true, but MAYBE in the future we'll find out it's not....." *lol*
Thanks for highlighting the 28 day menstrual cycle misconception! I’d be told my a previous gyno I probably had PCOS bc mine averaged longer. Was told I may need meds to get pregnant. Got hormonal tests done and they came back fine. Tracking my cycles a couple years later, and 32-35 days was the average. Because my cycles were a bit longer, I just ovulated at a different point in the cycle, around the exact same day in each cycle. My New OB is great. My Dr. recommended the book “Taking Control of your Fertility”. Have gotten pregnant twice, without the need of any medical intervention. Just shows how understanding your body and newer scientific evidence can empower you! Thanks for sharing!
@@OnlyARide What are you talking about? Yes, the title is most certainly grammatically incorrect. And I have no idea what transphobia has to do with this.
I was actually taught that you could ONLY get pregnant if you have sex during the first few days after your period ENDS, that ovulation pretty much immediately followed the end of the bleeding period and that was the only window for fertility. Gonna have to reframe that way of thinking for a bit, thanks for the info.
This information makes me question things about in vitro fertilization. Are we more likely to see "selection errors" when we remove the reproductive track's filtering system, and are there any drawbacks from it?
It is possible that some selection processes could be lost, but the female body has to also be prepared to accept the fertilized eggs when they are returned and it is during this time that eggs can be weeded out.
Could be part of the explanation for higher miscarriage rates during infertility treatments. But advanced maternal age (god how I hate that term) is still probably the main driving factor. It would be interesting, if possible/ethical, to study how that natural filtering system changes throughout one's reproductive life.
one little strange thing i've found with my cycle is that since coming off the contraceptive pill (i was on it for about 3 years) my cycle is now a week longer than it used to be. i was a pretty average 28 days now i'm looking at 35/36 days. i have read that it can take up to 6 months to have a regular cycle again but the past two have been consistent so i'm wondering if now i get an extra week between periods (wooo i guess)
The pill actually tells your body when to have a period. Those "placebo pills" in the pack trigger it. So the cycle you have now is probably your actual cycle. Same thing happened to me and that's what my doctor told me.
It was 28 days before you were on the pill? If you are concerned maybe consider supplementing with iron, b vitamins, and maybe a multivitamin or prenatal. These levels can affect your cycle also.
@@hyrunnisa997 i'm not too concerned, i have a pretty healthy diet and i do a good amount of exercise. i'm more just worried if my cycle is still getting back to normal and it is shorter one month and i'm not ready
This was super interesting. :O Also, no wonder we've got things wrong. I mean, there are people who, in today's day and age, think periods are like peeing and that we should just "pee it out and be done with it" or "squeeze so it doesn't come out when we don't want it to". lol. People are... stupid. But I'm glad science is at least going forward. :)
@@akaniotevanos9861something else crazy. Periods can happen without menstruation, even in those whom have never had a womb. So tell me how do I pee out a period without a womb?
An alien from another planet visited earth, and asked how human reproduction worked. After being given a lengthy and detailed explanation by his terrestrial hosts, he replied "Interesting. On my planet, that's how we make trucks...."
Knowing that we could make more ova is super cool, and I definitely thought we were born with all our eggs, but also, there goes my plan to donate all my eggs and never have another period.
S. Smith Oh please, modern education is merely an overglorified babysitting business getting you ready to follow the same schedule at your stupid job as an adult. Until highschool, that much homework is just busy work. Let kids be kids, school should be part time but most adults are slaves to their jobs (what's the alternative?) and have no choice to turn their child in to an institution to be shaped and molded by adults that have 30-35 students to 'raise'. Unless you meant science then that's a whole other rant, you'd have to ask my dad for that, he's the scientist.
@@melissaCgreenwood I mean, I got middle school courses that gave me the knowledge to test out if courses in highschool to get quite a few college credits. As someone who grow up in public school and would otherwise has massive debt right now, I think your lacking middle high was the issue...
I can appreciate that the more we learn about natural processes, the more often we find that there’s less instances of force and subjugation and more instances of working together to produce the best possible outcome. I would imagine that would correlate with changing mindsets. As we lean more toward the mentality that people are more similar than different and should be treated as such, we can more easily look at things through eyes not shrouded by bias and come to more correct conclusions.
Small correction: at 8:22 the narrator says "split first into pairs, and then single strands". And then he repeats that error shortly after. The second split of meiosis doesn't produce single strands. The DNA is still double stranded, it's just a single chromatid. I know it sounds picky, but students pick up on those errors and repeat them. :)
I second the correction. Each chromosome starts out as double-stranded DNA. When it is copied, the two strands start to split apart and simultaneously have their complementary strands being built. So even during replication, there is only a small section of each chromosome at any given time that is single-stranded. I don't believe that you ever encounter an entire single-stranded chromosome in a healthy human cell.
Also it's on average 38 weeks of pregnancy from making giggety to the birth. That's rather ten months despite the nine we usually speak about. I have three siblings and my mom always had us for 40 weeks.
The only month that actually has 4 weeks is February. Every other month has a couple extra days which makes up for the tenth month and makes it closer to 9 months.
i'm an irregular cycle lady (my worst times were 10 days every 20 days, 15 every thirty, and the 2 month period; all numbers r averages). i felt so wrong and obgyns just gave up me. now i have no period (i also did not get it until i was 16). good to know i am not messed up! except for the constant anemia, fainting, and disabling pain... at least it is no problem anymore. except i have neverending pregnancy scares. i go to the doctor every couple weeks not only due to disability but for tests.
Better than those wierdos tracking their gf's period on their phone. Wtf, I'll do that thanks 😓. I never understood how women can just ignore it. I need to plan my life around it because of how debilitating it is. I'd rather have the flu, it's waaay less painful.
@@melissaCgreenwood Maybe they both track it, to avoid the questions and conversations. It's not always creepy. You should talk to a doctor and get some contraceptives. There are many different kinds, so there's probably one out there that will make your life better
I only bleed for 2-3 days, but my cycle is only about 21-24 days. I also have PMDD & the hormone shift causes autoimmune flares. Psoriasis, Rosacea, chronic fatigue, & an undiagnosed pain disorder; all get worse right before the cramps & nausea hit. Not feeling exactly a favorite of the gods.
I don’t want to have kids but obstetrics and gynecology is so fascinating to me. Although I guess it’s almost more important to know how the intricacies of reproduction work so you can work against nature to avoid it lol. Thanks Scishow! 😆👍🏻
"I dont want to have kids" that'll change as you age. Eventually you'll reach an age where having children won't make sense and you'll see all your friends and possibly family raising young little children, all proud, talking about them every day, etc while you sit there alone. But if that genuinely doesn't bother you, which many would have a hard time believing because we're all Human beings and we're all wired to want the same things, then hey good for you. I myself am in my 30's and I still refuse to have kids, I make excellent money as an Aviation Engineer and love spending every bit of it on myself, vacations, ATV, nice house, cottage, travelling a lot. I'm sure eventually i'll go through a phase where i'll regret some decisions but i'll get over it, just as some parents have regrets but get over it. Why am I talking this much? I'm done now, enjoy your day.
sacr3 I have medical reasons as to why having kids would really really be a bad idea. Also, like you alluded to, if you don’t have kids you save a TON of money and can properly take care of yourself. Which is something I’ve yet to be able to do for just a household of one in my not-yet-graduated-college-level job. There’s also the ethical ramifications of bringing yet another human onto a planet that is actively dying before we’ve seen any promises that our world leaders are going to do anything to stop it, but that’s a WHOLE mess that probably isn’t worth getting into.
As a person who was diagnosed with premature ovarian failure at 16 and had the doctors basically go "ehh we don't really know why it happened sucks to be you I guess", I can tell you there is a lot we still don't know about reproduction.
@Michael Nilson Ironically because I don't naturally produce estrogen I have to take "the pill" to supplement the hormones otherwise I would be at a high risk of developing brittle bones at an early age and an increased risk of cancer. But yes I won't have to worry about any accidental pregnancy.
They don't mean the genes carried by the sperm. They mean somehow there is interaction between the sperm and the egg before the egg's final division which is before fertilization.
Would love it if you guys could do a video on myths about women’s reproductive health and birth control myths. Like how if you take the pill the “period” you get every month isn’t a real period. It’s just your body’s reaction to sudden change in hormones.
@@myoung6067 the ovulatory cycle and the menstrual cycle react to different hormone changes and are not necessarily dependent on one another. You can ovulate twice or more, or not at all within a menstrual cycle, and you don’t have to have a menstrual cycle in order to ovulate.

@@zebedeesummers4413 Add male anatomy along with it. You wouldn't believe how many people still think testicles will shrink if you ejaculate too often, because they think testicles are literally balls of semen, and apparently have no idea what the prostate does except cause cancer.
Even the 5-7 day average for menstruation doesn't account for everyone. Mine, for instance, is longer, which makes sense since I also have unusually heavy periods (at its heaviest, I fill up a pad within 2 hours. during the 1-3 heavy days of my period I usually don't get sleep for more than a couple hours at a time, and I get lightheaded a lot from blood loss and have to make sure I'm eating and drinking).
What about a video on scientific terms that have changed over time, such as Fallopian tube -> oviduct and hymen -> vaginal corona (I’m a sex ed teacher so these are the examples that come to mind for me)
Re 2:36: it should read 6.5% of people have 28 day cycles. Half of people have none at all. Why isn't there a word we can use for people with female reproductive systems?
If only we had a process we've been using since the beginning of mankind, which allowed us to go from ambiguous "oo oo aa aa" grunts to form distinct words, to clear up ambiguities in verbal communication. Maybe we could call this process.. language. Yes! Let's create a word to clear up this ambiguity, as we've always done, maybe something like "woman".
How about detecting pregnancies? The first time my ex-wife got pregnant we noticed that the dogs were gathering around her with very active noses. She miscarried that pregnancy. The next time she was possibly pregnant, the dogs were again gathering round, with the two small dogs on her stomach sniffing very intently. We looked at each other knowingly. This was before the home test kit or the doctors confirmation. Our son is now 15. During the pregnancy one of the small dogs was sleeping against my wife's tummy when the baby gave a kick. The dog sat up in shock and was throwing filthy looks at her tummy and the other dogs.
I'm currently pregnant. I did a lot of research while we where trying. I really appreciate these type of informative videos because it's so important for men and women to know their bodies. Thanks SciShow!
IDK if this is wrong, but I think person(s) and ovulation menstrual cycles is gender wrong. I'm a person and I've never ovulated or menstruated. Females do this, males don't, but I'm old school and maybe in science today, any person can menstruate. We're learning new things all of the time right? Like sperm and Ova have hands.
It is crazy how much of this I didn’t know before my husband and I started trying to conceive. It took us 8 months to get pregnant, so I did a lot of reading and tracking my cycles and I had no idea how complicated all of this was before pregnancy 😂
and i would think the biggest thing we get wrong is when parents and particularly women say they "make babies". all the parents do is...and the rest happens without their help, with the young life creating itself and its environment (placenta), Gibran is right "Your children are not your children. They are sons and daughters of Life's longing for itself. They come through you but not from you. "
This was helpful! I've also heard that a lot of data we currently have about the period for women to get pregnant (that it gets significantly more difficult after 40) is skewed from results back in the 1900s. Nowadays that's not necessarily true because of modern medicine. Is there science about the health of women's bodies getting pregnant and if there actually is an age range where it declines?
after 4 years i now catch you saying the 8:22 "final division" happens __after__ fertilization..........like wut? so like while the egg and the sperm are doing it's handshake it does the last split?
I found this video very informative and much needed. Liked it alot! But I struggled to keep up with the big words, especially during the ovulation part. Went just a tad to fast. Watched it over a few times to get it all :) good video.
And videos like these are actually offensive to progressives and increasingly number of science deniers, so creators have to make them as neutral as possible or mention animals more than human genders.
@@joshanonline ???? Gender identity and biological sex are two different concepts. It's also not unusual to talk about the reproductive systems of other animals and compare them to the ones of humans (since, y'know, they're quite similar in many ways). Where are you getting this narrative of "progressives hate sex ed" from? Because I've never heard a single progressive complain that sex ed is a thing. I've only heard conservatives do that.
All the academic journals I had to read for this honors class about gender/sex discussions had this idea that female reproductive organs are essentially dependent on the male reproductive organs because they just 'sit there' and don't create more ova throughout life. Thanks SciShow for giving me an update, I feel much better now.
Absolutely the best information, anyone a human body MUST know this. I think of my body as combination house and car for my being to live in and move about in this environment.Everybody has one and it's unbelievable to me that anyone would take care of their "house and car" because once you leave it you can't exist here.
Same. Id have 2 periods a month, skip 3 months, have a few average cycles.... on and on it went. Finally went on continuous BC, I've forgotten what periods are like.
I had allways been told a cycle was 28+-2 days, and if I am not stressed, it fits in this range for me. But I know from my mum, that when you are around menopause, it goes haywire. So much you need extra water and iron to avoid passing out from bloodloss plus gets random fevers
I was taught the basic version of everything in this video in sex ed over 15 years ago (though some of it I also got from my parents), which surprises me as my most notable memory of sex ed is that my teacher didn't recognize a diaphragm when discussing contraception.

People who dont have periods thought this I'm assuming 🤦🏽♀️
I mean, how much do you know about penises really? I'd be surprised if neither you nor a friend of your's didn't have gaps of knowledge when it comes to reproductive organs you don't have first hand experience with. (For the record I did know but only after helping a friend in highschool.)
I was always told the cycle was so close to the lunar cycle that most women could just remember the moon phase of their period, then use the moon phases already on calendars without marking stuff, except in puberty etc., which is exactly when someone would bother with an app, thus filling that study with more unusual periods than in the actual population. But that might all still just be a myth.
@@johngypsydoe862 Yeah "most women" would expect to at least see a little drift, like when you see the indicator lights flashing on two cars, for a while they'll appear to synchronise, flashing at the same time, but then move out of phase til they look like they're taking turns to flash etc. So, the lunar month length is 29 and between around 7 and 19 hours (as it's not a perfectly circular orbit) so even a cycle length of 28 days would progress through the lunar cycle backwards, being one day earlier each cycle. But cycle length is just how genes respond to blood chemistry, so changes in diet, hydration levels, sleep and exercise, other hormones from things like stress, all come into play. The more these follow fixed patterns, the more you'd expect various body clock cycles to too.
"2-7 days you're on your period" I feel mf scammed, I've had 10-12 day periods since the first time I got it. Now I have the implant and thr average is two weeks of bleeding. Being female is a scam and I would like a refund.

Yes!
Pun intended?
Have we had one about vaccinations yet?
Yeah, myth #2...most women already know this. My period always changes based on a lot of things, stress, medication, nutrition levels. Surgery! I lost my period for 2 months after surgery.
Yep. And while it's not statistically proven that cycles "sync up" I have seen and experienced so much anecdotal evidence that our hormones interact that it would be absurd to dismiss that.
There ARE many triggering/altering factors. But the nuance of those interactions makes it really iffy for science to pin down.
Periods can be affected due to outside stimuli.
Also, they can last as long as 3-5 weeks occasionally due to specific health issues.
Remember, the myth that ovulation occurs on day 14 of a woman's cycle, is where this joke came from:
"What do you call a couple who uses the Rhythm Method for birth control?"
"PARENTS!"
Thank you, Stefan Chin, for presenting this is a grown up, matter of fact manner without it being dry. Good job to all who took part in creating this Sci Show episode.
I dated a woman who had an ablation surgery to stop her periods. She literally would ovulate constantly and bleed nearly continuously for months on end. One full cycle every few days.
Oof that must've hurt a lot
Holy crap! I would have throttled the doctor until the they agreed to do it.
Like a chicken
Wait, are you saying this was AFTER the surgery and that she was normal before it, or are you saying that she had the surgery because this was what she was like naturally? Because it sounds like the effect of the surgery was the exact opposite of what was desired.

I was expecting something about hymens to be on this list and how everything most people know about them is wrong.

Well, Frau Ärztin, enlighten us.
That's because even premenstrual girls don't seem to have intact hymens anymore, so hymen talk is like, What's the use?
One study found 52% of sexually active women had intact hymens. Not to mention they can heal and don’t always “tear” the first time a woman has sex. The idea that “sex is supposed to hurt the first time” is horrible and dangerous.
Imperforate hymen is very rare, usually diagnosed after pelvic swelling for a period that cant get out. The hymen myths still abound.

Surely the biggest thing we still get wrong is treating both the menstrual and broader reproductive cycles as something dirty and taboo, to be avoided in everyday conversation. Which is what makes this video a breath of fresh air: the fact SciShow is not afraid to discuss something that is so often missing from public debates about issues related to sexuality.
Human reproduction was one of the most fascinating subjects I ever took in med school and even if I hadn't taken it then also took it at my first University and still found it to be extremely fascinating.

The most terrifying sentence I heard today
I totally accept that "we're always learning new stuff," really I do... but you'd think we'd have "how babies are made" nailed down by now.
Nope, like Inception, there's always another layer of understanding. When I went in for infertility consult (many moons and sad-periods ago), turns out they had discovered an entirely new major *hormone* (anti-Mullerian hormone, AMH, fun stuff) in the 12-15yrs or so between then and when I learned this stuff in school & from my first GYN.
I think a lot of it has to do with ethics.
Society in general isn't okay with growing human embryos in petri dishes for scientific research. Nor is society okay with taking a deep look into the reproductive systems of humans, particularly women's.
It's hotly politicized, all around the world.
That kind of controversial research is exactly what is needed to further our understanding of human reproduction in major ways.

Thanks for highlighting the 28 day menstrual cycle misconception! I’d be told my a previous gyno I probably had PCOS bc mine averaged longer. Was told I may need meds to get pregnant. Got hormonal tests done and they came back fine.
Tracking my cycles a couple years later, and 32-35 days was the average. Because my cycles were a bit longer, I just ovulated at a different point in the cycle, around the exact same day in each cycle. My New OB is great. My Dr. recommended the book “Taking Control of your Fertility”. Have gotten pregnant twice, without the need of any medical intervention.
Just shows how understanding your body and newer scientific evidence can empower you! Thanks for sharing!
5 Things We Get Still Wrong About Grammar
I KNOW RIGHT
Mistakes were made i guess?
@@OnlyARide No no, he was just pointing out that "still" should come before "get" in the title, not the other way around
I used to love the stories my grammar would tell me about the good one's days..😏
@@OnlyARide What are you talking about? Yes, the title is most certainly grammatically incorrect. And I have no idea what transphobia has to do with this.
I was actually taught that you could ONLY get pregnant if you have sex during the first few days after your period ENDS, that ovulation pretty much immediately followed the end of the bleeding period and that was the only window for fertility. Gonna have to reframe that way of thinking for a bit, thanks for the info.
This information makes me question things about in vitro fertilization. Are we more likely to see "selection errors" when we remove the reproductive track's filtering system, and are there any drawbacks from it?
It is possible that some selection processes could be lost, but the female body has to also be prepared to accept the fertilized eggs when they are returned and it is during this time that eggs can be weeded out.
Could be part of the explanation for higher miscarriage rates during infertility treatments. But advanced maternal age (god how I hate that term) is still probably the main driving factor. It would be interesting, if possible/ethical, to study how that natural filtering system changes throughout one's reproductive life.
I'm 35 and I was surprised how much I learned from this video.
Good work on a very informative video.
one little strange thing i've found with my cycle is that since coming off the contraceptive pill (i was on it for about 3 years) my cycle is now a week longer than it used to be. i was a pretty average 28 days now i'm looking at 35/36 days. i have read that it can take up to 6 months to have a regular cycle again but the past two have been consistent so i'm wondering if now i get an extra week between periods (wooo i guess)
The pill actually tells your body when to have a period. Those "placebo pills" in the pack trigger it. So the cycle you have now is probably your actual cycle. Same thing happened to me and that's what my doctor told me.
But if it is constantly 35 days then it is regular
It's likely that your period changed during those three years and you just didn't know it until you stopped taking the pills
It was 28 days before you were on the pill? If you are concerned maybe consider supplementing with iron, b vitamins, and maybe a multivitamin or prenatal. These levels can affect your cycle also.

I can appreciate that the more we learn about natural processes, the more often we find that there’s less instances of force and subjugation and more instances of working together to produce the best possible outcome. I would imagine that would correlate with changing mindsets. As we lean more toward the mentality that people are more similar than different and should be treated as such, we can more easily look at things through eyes not shrouded by bias and come to more correct conclusions.

Small correction: at 8:22 the narrator says "split first into pairs, and then single strands". And then he repeats that error shortly after. The second split of meiosis doesn't produce single strands. The DNA is still double stranded, it's just a single chromatid. I know it sounds picky, but students pick up on those errors and repeat them. :)
I second the correction. Each chromosome starts out as double-stranded DNA. When it is copied, the two strands start to split apart and simultaneously have their complementary strands being built. So even during replication, there is only a small section of each chromosome at any given time that is single-stranded. I don't believe that you ever encounter an entire single-stranded chromosome in a healthy human cell.
Also it's on average 38 weeks of pregnancy from making giggety to the birth. That's rather ten months despite the nine we usually speak about. I have three siblings and my mom always had us for 40 weeks.

It is crazy how much of this I didn’t know before my husband and I started trying to conceive. It took us 8 months to get pregnant, so I did a lot of reading and tracking my cycles and I had no idea how complicated all of this was before pregnancy 😂
and i would think the biggest thing we get wrong is when parents and particularly women say they "make babies". all the parents do is...and the rest happens without their help, with the young life creating itself and its environment (placenta), Gibran is right "Your children are not your children. They are sons and daughters of Life's longing for itself. They come through you but not from you. "
This was helpful! I've also heard that a lot of data we currently have about the period for women to get pregnant (that it gets significantly more difficult after 40) is skewed from results back in the 1900s. Nowadays that's not necessarily true because of modern medicine. Is there science about the health of women's bodies getting pregnant and if there actually is an age range where it declines?
This ..... Was .. helpful?
Really?
👍🇺🇲
You know what I'm gonna do
Im just gonna believe it
after 4 years i now catch you saying the 8:22 "final division" happens __after__ fertilization..........like wut?
so like while the egg and the sperm are doing it's handshake it does the last split?
I never heard you can't get pregnant on your period. I always heard it wasn't likely.
I found this video very informative and much needed. Liked it alot! But I struggled to keep up with the big words, especially during the ovulation part. Went just a tad to fast. Watched it over a few times to get it all :) good video.
thank you for talking about "people who get their period" instead of women!!!
this video is so much more in-depth than i expected...
The title is a clear product of RUclips's monetization system lmao 😂
And videos like these are actually offensive to progressives and increasingly number of science deniers, so creators have to make them as neutral as possible or mention animals more than human genders.
@@joshanonline ????
Gender identity and biological sex are two different concepts.
It's also not unusual to talk about the reproductive systems of other animals and compare them to the ones of humans (since, y'know, they're quite similar in many ways).
Where are you getting this narrative of "progressives hate sex ed" from? Because I've never heard a single progressive complain that sex ed is a thing. I've only heard conservatives do that.
So I knew there was a lot I didn’t know about how human reproduction works, but I didn’t know I was missing this much.
The title needs sorting out.
All the academic journals I had to read for this honors class about gender/sex discussions had this idea that female reproductive organs are essentially dependent on the male reproductive organs because they just 'sit there' and don't create more ova throughout life.
Thanks SciShow for giving me an update, I feel much better now.
What we should’ve learned in school...😢
I like that the sperm who broke the brick wall was wearing sunglasses 😂
I’m a simple person; I see a new SciShow video, I click
Absolutely the best information, anyone a human body MUST know this. I think of my body as combination house and car for my being to live in and move about in this environment.Everybody has one and it's unbelievable to me that anyone would take care of their "house and car" because once you leave it you can't exist here.
Before I went on bc my cycle ranged from 2.5 to 6.5 weeks. It was always a surprise lol
Firefoxwaffles I guess birth control wasn't the only reason you started taking the pill.
@@Primalxbeast not at all. I never took bc for the contraception. It was only ever to relieve my horrid horrid symptoms and my irregular cycles.
Same. Id have 2 periods a month, skip 3 months, have a few average cycles.... on and on it went.
Finally went on continuous BC, I've forgotten what periods are like.
I had allways been told a cycle was 28+-2 days, and if I am not stressed, it fits in this range for me. But I know from my mum, that when you are around menopause, it goes haywire. So much you need extra water and iron to avoid passing out from bloodloss plus gets random fevers
2:37 "thirteen percent of people"
too scared of the potential backlash to say women
I was taught the basic version of everything in this video in sex ed over 15 years ago (though some of it I also got from my parents), which surprises me as my most notable memory of sex ed is that my teacher didn't recognize a diaphragm when discussing contraception.
