Learn the role hormones play each month during your menstrual cycle, what causes ovulation, and what happens during the follicular and luteal phases?
The menstrual cycle has two main phases. The follicular phase, or proliferative phase, normally makes up the first 10–16 days of the cycle. The luteal, or secretory, phase comes right after ovulation and lasts for about 14 days, ending with menstruation if pregnancy didn’t occur.
What hormones are involved in the menstrual cycle? The menstrual cycle is regulated by several different hormones.

Stimulates estrogen and progesterone ...
Menstrual cycle, recurring fluctuations in hormone levels that produce physical changes in the uterus and ovaries to prepare the female body for pregnancy. In adult women, the menstrual cycle lasts anywhere from 21 to 40 days. Learn about the phases and hormonal control of the menstrual cycle.

The menstrual cycle is regulated by hormones. Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone .
