Abstract
OBJECTIVE: To determine if routine semen culture is useful in asymptomatic couples undergoing in vitro fertilization and embryo transfer (IVF-ET). DESIGN: Prospective data collection. SETTING: All cultures and IVF cycles were performed at the University of North Carolina in Chapel Hill, North Carolina. PARTICIPANTS: All asymptomatic couples undergoing IVF-ET from January 1989 through January 1990. INTERVENTIONS: Aerobic and anaerobic cultures were performed on semen samples obtained before IVF. MAIN OUTCOME MEASURES: Quantitative semen cultures were evaluated for both aerobic and anaerobic bacterial isolates. Fertilization and pregnancy rates (PRs) were compared in patients with positive and negative semen cultures. RESULTS: Eighty percent of cultures contained at least one bacterial isolate. Three of the four most commonly isolated bacteria were normal skin flora. Positive culture results had no effect on either fertilization or PRs. CONCLUSIONS: Bacterial contamination is common with semen collection, yet routine semen cultures are not beneficial in asymptomatic couples undergoing IVF-ET.
