The fertilization and subsequent cryopreservation of donated oocytes have enabled the resulting embryos to be quarantined for a minimum of 6 months, and to be thawed and replaced only after the donor has had a second negative human immunodeficiency virus (HIV) test. In the study described here, a total of 39 women had 56 embryo transfers, and 12 pregnancies (21% per transfer) were achieved. The logic of the protocol for minimizing the risk of infection of the recipient, which is in line with that of semen donation, is presented, together with an argument for the feasibility of such an approach.

D001755 Blastocyst A post-MORULA preimplantation mammalian embryo that develops from a 32-cell stage into a fluid-filled hollow ball of over a hundred cells. A blastocyst has two distinctive tissues. The outer layer of trophoblasts gives rise to extra-embryonic tissues. The inner cell mass gives rise to the embryonic disc and eventual embryo proper.

D004624 Embryo Transfer The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.
