Menstrual cycle - Tamil

#The menstrual cycle is regulated by the coordinated functions of the hypothalamus, pituitary, ovaries, and endometrium. The pulsatile secretion of gonadotrophin-releasing hormone from the hypothalamus stimulates the anterior pituitary to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which in turn stimulates the development of ovarian follicles and the production of ovarian steroids. A negative feedback mechanism is crucial for its control and regulation. During the follicular phase, the recruited follicle prepares for ovulation. After the LH surge and ovulation, the luteal phase begins. The follicular and luteal phases correspond to the proliferative and secretory phases of the endometrium, which develops during the proliferative phase and is maintained during the secretory phase to prepare for implantation of the fertilized embryo. The endometrium is shed during menses in the early follicular/proliferative phase, and the cycle continues.
****************************************
Note:- Estrogen is a female sex hormone.
Small amount of Estrogen is produced in the inner layer (active zone) of the adrenal cortex and stored in the middle layer (storage zone) of the Adrenal cortex.
Large amount of Estrogen is secreted by developing follicles of the ovary .
It controls female reproduction and sexual development, including the development of female characteristics such as the growth of breasts.
****And the adrenal glands might be responsible for the relatively important source of estrogen production in the aged woman and before puberty.
