A study conducted by Dr. Jose Bellver published by the Fertility and Sterility of American Society for Reproductive Medicine,
Objective: analyze the reproductive outcome of recipients of donated ova according to their body mass index (BMI) over twelve-year retrospective cohort analysis in several academic fertility clinics.
Result: In vitro fertilization laboratory parameters did not differ according to BMI. However, implantation, pregnancy, clinical pregnancy, twin pregnancy, and live-birth rates were significantly reduced as BMI increased. In the lean, normoweight, overweight, and obese groups, the implantation rate was 40.4%, 39.9%, 38.5%, and 30.9%, clinical pregnancy rate was 56.9%, 55.9%, 54.3%, and 45.3%, and live-birth rate was 38.6%, 37.9%, 34.9%, and 27.7%, respectively. However, clinical miscarriage rates were similar in all the groups.
Female obesity impairs the reproductive outcome of ovum donation probably as a result of reduced uterine receptivity.
There is also study conducted to evaluate effect of acupuncture and Chinese herbal medicine in the helping people with infertility due to the obesity or over weight.
