About

Ovulation induction (OI) using gonadotropins is one of the most widely prescribed treatments of infertility. One common problem encountered while attempting OI using gonadotropins is premature ovulation. The purpose of this study is to examine the effect of a single injection of a medication, called ganirelix, to prevent premature ovulation. Patients will be divided into two groups. In the first group, gonadotropins will be used to stimulate the ovaries. In the second group gonadotropins will be used in addition to a single injection of ganirelix, a gonadotropin releasing hormone (GnRH) antagonist. Pregnancy rates will be compared between groups.

Full description

A randomized prospective study will be performed on patients attempting pregnancy using ovulation induction/intra-uterine insemination (IUI). Patients will be randomly assigned to one of two protocols:

Protocol A (control group): On menstrual cycle day 3, the patient will start gonadotropins (Follistim) injections at a starting dose of 75-150 IU and monitored according to the discretion of the treating physician. When the leading follicle reaches a size of at least 18mm, intramuscular human chorionic gonadotripin (hCG) (10,000 IU) is administered, followed by two inseminations, one at 12 hours after hCG, and the other at 36 hours. All patients will have luteal support using progesterone vaginal suppositories at a dose of 200mg two times per day (BID). Pregnancy testing will be scheduled at 2 weeks after the IUI. The treatment cycle typically lasts from 8-13 days, depending on the patient's response.

Protocol B (study group): On menstrual cycle day 3, the patient will start gonadotropins (Follistim) injections at a starting dose of 75-150 IU and monitored according to the discretion of the treating physician. When the leading follicle reaches a size of 13-14mm in mean diameter, or when the estradiol level reaches a level of 400 pg/ml, ganirelix injection at the standard dose of 250mcg is given once subcutaneously. When the leading follicle reaches a size of at least 18mm, intramuscular hCG (10,000IU) is administered followed by two inseminations, one at 12 hours after hCG, and the other at 36 hours. All patients will have luteal support using progesterone suppositories at a dose of 200mg BID. Pregnancy testing will be scheduled at 2 weeks after the IUI. The treatment cycle typically lasts from 8-13 days, depending on the patient's response.

Patients will be randomized, via computer generated program, in a 1:1 fashion.
