promote ovulation and stimulate the ovaries to produce estrogen and progesterone. Estrogen and progesterone stimulate the uterus and breasts to prepare for possible fertilization
Hormones play a fundamental role in regulating the menstrual cycle, a complex process involving various hormonal changes and physiological events in the female reproductive system. The primary hormones involved in this cycle are:
1. Follicle-Stimulating Hormone (FSH) :- Secreted by the pituitary gland, FSH stimulates the growth and development of follicles (fluid-filled sacs in the ovaries) that contain immature eggs.
2. Luteinizing Hormone (LH) :- Also produced by the pituitary gland, LH triggers ovulation, the release of a mature egg from the follicle.
3. Estrogen :- Produced primarily by the developing follicles, estrogen levels rise during the first half of the menstrual cycle. It stimulates the thickening of the uterine lining (endometrium) in preparation for a potential pregnancy.
4. Progesterone :- After ovulation, the remaining part of the follicle (now called the corpus luteum) produces progesterone. This hormone helps maintain the uterine lining for a possible embryo implantation and supports early pregnancy.
The menstrual cycle typically has two main phases:
1. Follicular Phase :- This phase begins on the first day of menstruation. FSH stimulates the growth of several follicles in the ovaries, each containing an immature egg. As these follicles grow, they produce estrogen, which causes the endometrium to thicken.
2. Luteal Phase :- Ovulation occurs around the middle of the menstrual cycle when high levels of LH trigger the release of the mature egg from the follicle. After ovulation, the empty follicle becomes the corpus luteum and secretes progesterone. If fertilization does not occur, the corpus luteum breaks down, causing a drop in estrogen and progesterone levels. This drop leads to the shedding of the uterine lining (menstruation), marking the start of a new cycle.
The interplay and balance of these hormones orchestrate the menstrual cycle, regulating ovulation, preparing the uterus for a potential pregnancy, and ensuring the cyclical changes necessary for reproductive health. Any disruptions or imbalances in these hormonal levels can affect the regularity and characteristics of the menstrual cycle.
