FSH has two functions?

One of the functions of FSH in the menstrual cycle is for development of the primary follicle during the first few days of the menstrual cycle, and there is a small peak of this hormone between approximately days 1-6. As oestrogen levels increase (oestrogen is secreted by the theca interna of the secondary oocyte) this feeds back negatively, thus decreasing the level of FSH until approximately day 12. Oestrogen levels reach a peak between days 11 and 12, and then start to decline. As levels of oestrogen decline, FSH levels start to increase once more, and there is a small peak of FSH on day 14 when ovulation occurs. FSH is responsible also for the choice of the dominant follicle; a woman has many follicles, but only one (or 2 if there are dizygotic twins) will mature. This appears to depend on the number of FSH recpetors on the surface of the follicle, i.e the follicle that has most receptors will be the one which matures. To answer your question, then, I would say that the 2 main functions of FSH in the menstrual cycle are: 1) The initiation of follicular development, and general development of the primary follicle 2) Choice of the dominant follicle, i.e the follicle which will be ovulated. I hope that helps: I am currently trying to answer the same question, and struggled to find a second function of FSH other than the initiation of follicular development!

How can fsh help produce an egg?

FSH is the major survival factor that rescues the follicles from atresia (programmed death of the somatic cells of the follicle and oocyte). In the luteal-follicle phase transition period the serum levels of progesterone and estrogen (primarily estradiol) decrease and no longer suppress the release of FSH, consequently FSH peaks at about day three (day one is the first day of menstrual flow). The cohort of small antral follicles is normally sufficiently in number to produce enough Inhibin B to lower FSH serum levels. As a woman nears perimenopause the number of small antral follicles recruited in each cycle diminishes and consequently insufficient Inhibin B is produced to fully lower FSH and the serum level of FSH begins to rise. When the follicle matures and reaches about 10 mm in diameter it starts to secrete significant amounts of estradiol. Normally in humans only one follicle becomes dominant and survives to ovulate, the remaining follicles in the cohort undergo atresia. The increase in serum estradiol levels cause a decrease in FSH production by inhibiting GnRH production in the hypothalamus. The decrease in serum FSH level causes the smaller follicles in the current cohort to undergo atresia as they lack sufficient sensitivity to FSH to survive. Occasionally two follicles reach the 10 mm stage at the same time by chance and as both are equally sensitive to FSH both survive and grow in the low FSH environment and thus two ovulations can occur in one cycle possibly leading to non identical twins.


What is the FSH?

FSH :-abbreviation for follicle stimulating harmone.


What does the medical abbreviation FSH mean?

FSH means follicle stimulating hormone.


Do both Men and Women manufacture FSH?

Yes, both men and women produce follicle-stimulating hormone (FSH). In women, FSH helps regulate the menstrual cycle and is essential for ovarian function, while in men, FSH is important for sperm production.
