title: Pregnancy following in vitro fertilization and embryo transfer using pure human serum as culture and transfer medium.
abstract: Pure heat-inactivated serum of patients adjusted to 280 mOsm was used for preincubation, insemination, and transfer of oocytes in an IVF-ET program. In patients where the oocyte recovery yielded more than two oocytes, two oocytes were chosen randomly for serum cultivation. The 15th patient of that series became pregnant after a transfer of two serum-cultured embryos. The follow-up weekly clinical investigation and ultrasound revealed a normal single pregnancy, now in the 20th week.
