Whynott RM, Summers KM, Van Voorhis BJ, et al. - Researchers conducted a retrospective cohort study investigating if body mass index (BMI) influences intrauterine insemination treatment success. They assessed a total of 3,217 intrauterine insemination treatment cycles in 1,306 patients and identified no negative effect of a BMI between 25 and 29.99 kg/m ² or ≥ 30 kg/m ² on live birth after intrauterine insemination. Per findings, a possible correlation may exist between obesity and a higher risk of biochemical pregnancy after intrauterine insemination.
