Birth from replacement of frozen-thawed embryos after failure of gamete intra-fallopian transfer: a successful pregnancy case.
The patient was 8 years subfertile and had failed other forms of treatment when she was enrolled in the GIFT program. Of the total of 16 oocytes recovered 4 were transferred and the remaining 12 inseminated with her husband's sperm. Four resulting embryos were frozen. When she did not conceive, the 4 embryos were thawed 3 months later and replaced into her. She conceived and recently delivered a pair of twins. The protocol will be discussed in detail. Cryopreservation of embryos therefore may increase the patient's chance of pregnancy in a GIFT program.
