What are follicle stimulating hormone and ganirelix?
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.
Ganirelix is a man-made protein that inhibits the actions of the naturally-occurring hormone gonadotropin-releasing hormone (GnRH).
Follicle stimulating hormone and ganirelix are used together in the treatment of infertility. 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. Ganirelix is used to regulate hormone response during medication treatments for infertility in women.
Follicle stimulating hormone and ganirelix may also be used for purposes other than those listed in this medication guide.
