Follicle stimulating hormone (FSH) is a naturally occurring hormone. FSH is important in the
development of follicles (eggs) produced by the ovaries. FSH is also important in the development of
sperm.
Follicle stimulating hormone is used to stimulate a follicle (egg) to develop and mature. It is used
when a woman desires pregnancy and her ovaries can produce a follicle but hormonal stimulation is not
sufficient to make the follicle mature. Follicle stimulating hormone is also used to stimulate the
development of multiple eggs for in vitro fertilization. Follicle stimulating hormone can be used by men
to increase the production of sperm.
Follicle stimulating hormone may also be used for purposes other than those listed in this
medication guide.
