Full term delivery following cryopreservation of human embryos for 7. 5 years.
Successful pregnancy in a 44 year old woman is described following the transfer of embryos which were cryopreserved for 7.5 years. The embryos were obtained during a gamete intra-Fallopian transfer (GIFT) procedure in 1989. To our knowledge this is one of the longest published periods of cryopreservation of embryos which has resulted in a healthy baby. This report illustrates the previously presumed viability and normality of human embryos undergoing long-term cryopreservation. Additionally, it emphasizes the importance for advanced reproductive technique programmes and patients to review and update their embryo status.
