How can fsh help produce an egg

Through an interchange of information between the ovary and the brain, the most mature eggs will ovulate while the less mature eggs will regress. This is why human beings only ovulate one egg at a time, unless they are taking fertility hormones. When the brain detects that the ovary is struggling to make eggs, it drives the ovary harder and raises its FSH production.

A healthy ovary responds to an elevated level of FSH by producing several mature eggs. As a woman ages naturally, her FSH level will rise and reaches its maximum level in menopause when the egg supply is exhausted.

If you have an unusually high level of FSH at a young age, it may mean you have fewer eggs available to reach maturity. Since women with mild FSH elevation still menstruate regularly, the term is often referred to as diminished ovarian reserve DOR. This is contrast to menopause when all eggs are exhausted. One sign of diminishing ovarian reserve may be a shortening of the menstrual cycle interval or decrease in menstrual flow.

Unlike other body parts, the ovary produces its lifetime supply of eggs before birth. Other names: follitropin, FSH, follicle-stimulating hormone: serum. What is it used for?
