P-151: Assisted Reproductive Technology Outcomes in Too Young and Young Patients:Single Embryo Transfer versus Multiple Embryo Transfer

Background: This retrospective study compared pregnancy outcomes from single embryo transfer (SET) with multiple embryo transfer (MET) in too young (≤25 years) and young (>25 years) infertile patients. Materials and Methods: Data from infertile patients who referred for ART treatment to Yazd infertility center during 1992 to 2012 were studied retrospectively. Records of patients with SET or MET were studied in two groups: ≤ 25 (375 patients), and >25 years (346 patients). Demographic data including age, job, place of residency, clinical information, including cause and duration of infertility, type of infertility and kind and number of treatment, details of ART treatment cycles consisting number of antral follicles, number and grade of oocyte, semen analysis, number and grade of embryos, number of transferred embryos, and pregnancy outcomes were compared. Results: In≤ 25 years group the mean number of follicles >14mm 11.03, the number of oocytes 9.71, the number of MII oocytes 8.38, and the Grade of transferred embryos was 17.19. In >25 years group the mean number of follicles >14mm 9.26, the number of oocytes 8.45, the number of MII oocyte 7.23, and the Grade of transferred embryos was 16.99. The pregnancy rate from SET in ≤25 years group was 15.8% and from MET was 29.4%. In >25 years group, the pregnancy rate from SET was 11.5% and from MET was 39.3%. Conclusion: The pregnancy outcomes with SET or MET didn't differ in very young infertile women. So, it is better to perform SET to avoid multiple pregnancy complications.
