Initial experience with a donor egg bank.Akin JW, Bell KA, Thomas D, Boldt J Department of Obstetrics and Gynecology, University of Kentucky College of Medicine, Lexington, Kentucky, USA. jakin94939@aol.com OBJECTIVE: To report on the establishment of a commercial donor egg bank (CryoEggs International, LP) and to present our initial experience from the first four patients to receive eggs. DESIGN: Case report. SETTING: Private fertility clinic. PATIENT(S): The four recipient women were aged 43, 43, 40, and 33 years. All had cycle day FSH levels greater than 25 mIU/mL. All were given the option of fresh donor egg IVF but opted to use frozen donor oocytes. INTERVENTION(S): Purchased and quarantined frozen donor eggs were thawed and inseminated using intracytoplasmic sperm injection (ICSI). Subsequent embryos were transferred on day 3. MAIN OUTCOME MEASURE(S): Clinical pregnancy as defined by presence of cardiac activity. RESULT(S): There was a thawed egg survival rate of 76%, a fertilization rate of 74%, a pregnancy rate (PR) of 50%, with an average of 2.75 embryos per transfer and an implantation rate of 27%. CONCLUSION(S): Although very preliminary, these results indicate that more widespread use of frozen donor eggs obtained from a commercial egg bank may be feasible in the future, changing the landscape of donor egg IVF.
