SUCCESSFUL PREGNANCY AND BIRTH AFTER TRANSFER OF DONATED EMBRYO FERTILIZED IN VITRO

A case of human pregnancy and birth after transfer of a donated embryo fertilized in vitro is reported. The ovulatory cycles of the donor and recipient were synchronized by induction of owla- tion. The donor was a 29-year-old woman with prim- ary infertility, from whom 11 00cytes were recovered after stimulation with gonadotropins. The recipient was a 29yearold woman with secondary infertility because of bilateral tubal ligation performed nine years ago and she failed in a trial of the in vitro fertilization program* Six of the 11 00cytes from the donor were fertilized and underwent cleavage. Three of the six embryos were returned to the donor and the others were transferred to the recipient. No pregnancy occurred in the donor but pregnancy was confirmed in the recipient and a normal healthy male baby weighing 3 000 g was safely born. Key issues and indications of donated embryo transfer are dis- cussed in detail.
