Abstract
Increased body mass index (BMI) might have an adverse effect on pregnancy. However, the influence of BMI on the pregnancy outcomes after artificial insemination with donor’s sperm (AID) had been rarely reported. This study aimed to investigate the correlation between BMI and AID. The pregnancy outcome of 8570 AID cycles was retrospectively analyzed. BMI was categorized as underweight (<18.5 kg/m2; group A), normal weight (18.5–23.9 kg/m2; group B), overweight (24–27.9 kg/m2; group C), and obese (≥28 kg/m2; group D). The results showed that cumulative pregnancy rate and cumulative live birth rate in groups A, B, C and D tended to decrease as BMI increased; however, abortion rate, and ectopic pregnancy rate in groups A, B, C, and D exhibited a gradual increase in the tendency. Cesarean delivery rate also increased as BMI increased. Birth defect rate in the group D were significantly higher than that in the group A. Interestingly, the pregnancy rate was gradually decreased with increasing age in groups A, B, and C, but this was not observed in the group D. The findings suggested that BMI can affect the pregnancy outcomes after AID; it is important to achieve a normal BMI prior to AID treatments.
