Inclusion Criteria: The target population includes couples undergoing IVF. All eligible couples will be asked to join the study. Study participants will be recruited from the Reproductive Endocrinology Clinic at University of California at San Francisco Center for Reproductive Health.

Male factor infertility diagnosis should be cleared for eligibility by the PI based on previous patient history of fertilization outcomes and/or expected fertilization outcomes of the cause of male factor infertility based on known scientific data. * Ovulation trigger less than or greater than 36 hours to oocyte retrieval * Serum estradiol level \>5,000 pg/ml on the day of expected trigger due to high risk of OHSS
