Which spermatozoon should be eliminated in ICSI? (original) (raw)

correlation with peak estradiol level (r¼-0.2, p¼0.04). Donors' BMI had a positive correlation with the recipients' BMI (r¼0.26, p<0.01) and the number of embryos transferred (r¼0.37, p<0.01). Donors' BMI had no effect on the length of stimulation, gonadotropin use, number of oocytes retrieved, embryo quality, pregnancy rate, and birth weight. CONCLUSIONS: Oocyte donor BMI demonstrates no negative impact on live birth rates in donor-recipient IVF cycles. However, it is noted that overweight and obese donors are older, which may result in an increase in the number of embryos transferred to the recipients.
