Clomiphene & Letrozole

Clomiphene

Clomiphene (Clomid) is a medication that is administered from Cycle Day 3 through 7, or Cycle Day 5 through 9.  Clomiphene works by causing the pituitary gland in your brain to release more Follicle Stimulating Hormone (FSH) that it normally does.  The increased FSH allows 2-3 eggs (oocytes) to mature in one cycle instead of 1 egg (oocyte).  Clomiphene is also used to help patients who have difficulty with releasing the egg from the uterus (ovulation).  If you have already used Clomiphene for 2 or 3 cycles and have not become pregnant, you should make an appointment with a fertility specialist to discuss other options.

Letrozole

Letrozole (Femara) is a medication that is administered from Cycle Day 3 through 7, or Cycle Day 5 through 9.  Letrozole works similarly to Clomiphene by causing the pituitary gland in your brain to release more Follicle Stimulating Hormone (FSH) that it normally does.  The increased FSH allows 2-3 eggs (oocytes) to mature in one cycle instead of 1 egg (oocyte).  Letrozole is also used to help patients who have difficulty with releasing the egg from the uterus (ovulation).  If you have already used Letrozole for 2 or 3 cycles and have not become pregnant, you should make an appointment with a fertility specialist to discuss other options.
