The successful use of human amniotic fluid for mouse embryo culture and human in vitro fertilization, embryo culture, and transfer.
The development of mouse and human embryos was assessed in human amniotic fluid to determine its suitability as a culture medium for human in vitro fertilization (IVF). Two-cell mouse embryos developed to blastocysts after 72 hours at rates similar to that in Whittingham's T6 + 10% fetal calf serum. Significantly more mouse embryos hatched in amniotic fluid. No difference was found between individual patient's amniotic fluids obtained at 16 to 21 weeks' gestation. A preliminary trial comparing amniotic fluid with T6 + maternal serum in human IVF showed no significant difference in fertilization rate and embryo development during 42 to 48 hours in vitro. Expanded blastocysts were obtained in amniotic fluid after 5 days in vitro. Four pregnancies were obtained in 9 patients' transferred embryos grown in amniotic fluid and with 2 or 12 patients' transferred embryos grown in T6 + maternal serum.
