Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to compare semen parameters with in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) when male factor infertility patients abstain from ejaculation more than 48 hours (routine care) or less than 24 hours from the day of the partner's oocyte retrieval. The investigators hypothesize that total motile sperm count will be improved with ejaculatory abstinence (EA) less than 24 hours. Information from this trial could allow investigators to optimize chances for a successful pregnancy in patients who need IVF/ICSI.
