Follitropin alfa is a hormone identical to follicle-stimulating hormone (FSH) produced by the pituitary gland. FSH helps to develop eggs in the ovaries.
Follitropin alfa is used as a fertility medicine to develop eggs in women who have not been able to become pregnant because of problems in ovulation. Also, many women wanting to become pregnant will use this medicine while enrolled in a fertility program (assisted reproductive technology [ART]) that uses procedures such as in vitro fertilization (IVF) or embryo transfer (ET). Follitropin alfa may be used with other medicines for these purposes.
Follitropin alfa is also used as a fertility medicine to help men with low sperm counts produce more sperms. Treatment with human chorionic gonadotropin should come before treatment with follitropin alfa. This pretreatment elevates the amount of testosterone to the correct level. Treatment with human chorionic gonadotropin should continue as long as follitropin alfa is being used.
Some patients may be treated with another hormone called gonadotropin-releasing hormone agonist (GnRHa) before starting treatment with follitropin alfa. GnRHa reduces the amount of FSH released from the pituitary gland. This is done so that the doctor can replace their FSH with follitropin alfa in the proper amounts each day to achieve fertility.

It is very important that your doctor check your progress often at regular visits to make sure that the medicine is working properly and to check for unwanted effects. Your doctor will probably want to follow the developing eggs inside the ovaries by doing an ultrasound examination and measuring hormones in your blood stream. After you no longer receive follitropin alfa, your progress still must be checked for at least 2 weeks.
If your doctor has asked you to record your basal body temperatures (BBTs) daily, make sure that you do this every day. Using a BBT record or some other method, your doctor will help you decide when you are most fertile and when ovulation occurs. It is important that sexual intercourse take place around the time when you are most fertile to give you the best chance of becoming pregnant. Follow your doctor's directions carefully.
If abdominal pain occurs with use of follitropin alfa, discontinue treatment and report the problem to your doctor immediately. Do not receive the injection of human chorionic gonadotropin (hCG) and avoid sexual intercourse.
