To determine if IVM of oocytes from unstimulated cycle is a treatment option for patients who did not deliver after standard IVF-ET.
Twenty three women with PCO, thirteen of them with normal cycles and all <35 years old, who failed IVF served as their own control. During the control IVF cycle patients were stimulated with 1730.7 ± 639.5 IU recombinant FSH, a long Buserelin acetate protocol was used and embryo transfer was performed on day 2 or 3 after ICSI. After failed IVF immature oocytes were aspirated transvaginally from antral follicles during spontaneous menstrual cycle. Embryo transfer was performed 2 or 3 days later.
11.4 ± 4.8 mature oocytes and 6.7 ± 3.2 embryos were produced with IVF, which served as the control, compared to 9.7 ± 4.5 mature oocytes and 6.2 ± 3.2 embryos with IVM. There was one clinical pregnancy in the IVF group which did not result in a live birth where as five singleton and one pair of twins with healthy live births and one miscarriage in the IVM group.
IVM does not involve ovarian stimulation with possible financial and health consequences. İt may be an useful treatment after unsuccessful IVF.
