Hormones that induce ovulation and regulate the ovulatory cycle
Introduction
The key to the ovulatory cycle resides within the ovaries, and the primary hormone that regulates the ovulatory cycle is Estradiol. Every month, a follicle (egg) is randomly selected to release from the ovary. The first day of menstruation marks the beginning of the ovulatory cycle, and the start of the follicular phase. During the first 3–5 days of menstruation, Follicle-stimulating hormone (FSH) is triggering the growth of immature ovarian follicles. Estrogen is steadily increasing during this time; aiding in follicle development, thickening the endometrial lining in the uterus and in a general sense, promoting sociosexuality (Gray and Garcia 2013). A few days before the end of the follicular phase, estrogen surges as luteinizing hormone begins to rise, ultimately peaking when the follicle is released at the point of ovulation. When the...
