Study Summary
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.
Primary Outcome
total motile sperm (million sperm) is calculated from the semen analysis by calculating: volume x concentration x motility. This gives the total motile sperm value. The difference in total motile sperm was calculated from the participants baseline semen analysis (previous analysis before starting IVF treatment) to the semen analysis the day of the egg retrieval. The mean calculated can be interpreted as a decrease (change) in total motile sperm from the participants baseline semen analysis to th
