Study Summary

Many infertile patients have a decreased chance of becoming pregnant when using in vitro fertilization (IVF). For these patients, many different treatments are available, but none of them have been shown to be better than the others. We are testing which of three different treatments are better than the others. Patients who are expected to have a decreased response to ovarian stimulation will be randomized to either a microflare protocol, an antagonist protocol, or a demi-halt protocol.

Interventions

  • DRUG Microflare protocol for IVF
  • DRUG Antagonist protocol for IVF
  • DRUG Demi-halt protocol for IVF
