Abstract
OBJECTIVE: To determine whether body mass index (BMI) affects intrauterine insemination treatment success. DESIGN: Retrospective cohort study. SETTING: Academic medical center. PATIENT(S): A total of 3,217 intrauterine insemination treatment cycles in 1,306 patients. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Primary outcome was live birth rate stratified by BMI. Secondary outcomes included rates of clinical pregnancy (defined as an intrauterine pregnancy with a heartbeat present on ultrasound), multiple gestation, biochemical pregnancy, missed abortion, ectopic, and spontaneous abortion. RESULT(S): Women with BMI 25 to 29.99 kg/m2 or ≥30 kg/m2 were equally likely to have a live birth as women of normal BMI. Women with BMI ≥30 kg/m2 did have a higher likelihood of biochemical pregnancy than women with normal BMI. CONCLUSION(S): A BMI between 25 and 29.99 kg/m2 or ≥30 kg/m2 does not appear to have a negative effect on live birth after intrauterine insemination. Obesity may be associated with a higher risk of biochemical pregnancy after intrauterine insemination.
