The treatment duration will be approximately 4 weeks with pulsatile GnRH or placebo and 5 days with Clomiphene Citrate or placebo. All subjects will be screened based on inclusion/exclusion criteria, medical/infertility history and general safety assessments. Subjects that complete screening will be dispensed 100 mg of oral progesterone twice a day for 10 days to induce uterine bleeding. On Cycle Day 5 from the start of bleeding the subject will be randomly assigned to 1 of 7 treatment groups. All subjects will be monitored weekly throughout the 4 week treatment period for ovulation and intercourse will be timed. All subjects will be required to return to the study center for a total of 8 visits. In addition, all subjects with a confirmed clinical pregnancy will be monitored until fetal heartbeat is confirmed at approximately 5-6 weeks gestation
