Final Lecture of Female Reproductive Cycle

Increased estrogen levels are linked to increased libido, especially as they peak prior to ovulation.

The follicle transforms into the corpus luteum, which secretes progesterone to prepare the uterine lining for potential implantation.

FSH and LH initiate the maturation of primordial follicles, which secrete estrogen necessary for endometrial buildup.

The corpus luteum secretes progesterone to maintain the uterine lining. It functions for about 10-14 days if pregnancy does not occur, after which it degenerates.

6-12 primary follicles start to develop in response to FSH and LH stimulation.

A fall in estrogen and progesterone levels from the previous cycle triggers the start of menstruation.

Testosterone levels in men are low until puberty, peak during adolescence, and remain relatively stable with minor fluctuations. In contrast, women experience significant monthly fluctuations in estrogen levels during reproductive years, which decrease to low levels at menopause.

If pregnancy does not occur, progesterone and estrogen levels fall, leading to the shedding of the uterine lining and the start of menstruation.

Progesterone, secreted by the corpus luteum, is primarily responsible for the thickening of the endometrial lining post-ovulation.

FSH promotes the development of multiple follicles, but the one with the highest estrogen secretion becomes the dominant follicle, inhibiting others through negative feedback mechanisms.

The significant and regular hormonal fluctuations can affect physical and emotional states, leading to symptoms such as mood swings, cramps, and changes in libido.

Estrogen and later progesterone cause the buildup and maintenance of the uterine lining, making it conducive for implantation if fertilization occurs.

Estrogen promotes the buildup of the endometrial lining and stimulates libido. It is primarily secreted by developing follicles.

A significant decrease in estrogen levels signals the end of menopause.

The LH spike causes the rupture of the dominant follicle and the release of the egg, marking ovulation.
