      Kudos for the Video! Excuse me for butting in, I would appreciate your opinion. Have you heard about - Parlandealey Increasing Platelets Process (search on google)? It is an awesome one of a kind product for revealing the trick to eradicate your erectile disfunction minus the hard work. Ive heard some unbelievable things about it and my GF after a lifetime of fighting got cool success with it.

      This was great, thanks, I have been researching "what causes erection" for a while now, and I think this has helped. You ever tried - Meyylan Konophia Theorem - (do a google search ) ? Ive heard some super things about it and my mate got excellent success with it.

    Can I just say how much I appreciate you? You explain clearly, and with humor. You answer the "why" questions my poor professors are getting tired of. I'm working on my BSN now and plan to move on to a PA program once I'm done (and find the money). Seriously, I think we're about the same age, but I want to be like you when I "grow up." So, sincerely, thank you!

    I have watched all twenty-four videos on Endocrinolgy, they have been a pleasure to watch. Surprisingly, my mind drifted very little. The presentations are informative and detailed, more importantly they keep your attention. All to often, I have sat through lectures of all kinds on many subjects and zoned out, not here.

    In your illustration, it appears that you have LH and FSH being released from the posterior pituitary, with the hypophyseal portal system also going to the posterior pit. Just based off of the positioning of the Arcuate and preoptic nuclei - FSH and LH should be coming from anterior, with oxytocin and ADH (vasopressin) coming from posterior pit. Great video!

    15:36 To be more specific can we say that instead of conversion from cholesterol to testosterone there is actually conversion of weak sex hormones (i.e. DHEA and androstenedione) into testosterone. As cholesterol to weak sex hormones conversions are done in Zona reticularis in adrenal cortex (i.e. Gonadocorticoid pathway).
