Pregnancy established in an infertile patient after transfer of an embryo fertilized in vitro where the oocyte was donated by the sister of the recipient.
A successful pregnancy in a patient suffering from infertility due to severe tubal disease has been achieved following the transfer of embryos fertilized in vitro following the donation of oocytes by the sister of the recipient. Both sisters ovulated irregularly and asynchronously. The donor's menstrual cycle varied from 24 to 30 days and the recipient's cycle varied from 23 to 26 days. Synchronization of ovulation was achieved by matching the onset of their menstrual cycles prior to treatment by in vitro fertilization and by manipulating the follicular phase of both the donor and the recipient during the cycle of treatment. Ten oocytes were collected from the donor and all were inseminated with spermatozoa from the recipient's husband. Nine normal embryos developed and three were transferred to the uterus of the recipient sister, 55 hr after laparoscopic egg collection. A normal singleton pregnancy resulted.
