This new cycle was controlled by the advanced communications out-of hormones: luteinizing hormonal, follicle-revitalizing hormones, and the female gender hormone the hormone estrogen and progesterone .

Thus, the top levels of your thickened lining of one’s uterus (endometrium) falter and they are lost, and you can menstrual bleeding occurs. About any of it date, the latest hair follicle-stimulating hormonal peak expands somewhat, revitalizing the development of numerous hair follicles regarding the ovaries. (Follicles was sacs filled with fluid.) Per follicle include an enthusiastic egg. After contained in this phase, as follicle-revitalizing hormones peak reduces, usually one follicle continues to create. This hair follicle produces estrogen . Estrogen levels raise continuously.
Brand new ovulatory phase begins with a rise in luteinizing hormonal and you can follicle-exciting hormonal account. Luteinizing hormones produces eggs discharge (ovulation), which will takes place sixteen to thirty two hours following surge begins. The latest estrogen height decrease within the surge, in addition to progesterone level begins to raise.
From inside the luteal stage, luteinizing hormones and you may follicle-exciting hormonal membership disappear.
