REZULTATI I ISKUSTVA NAKON HILJADU CIKLUSA VANTELESNE OPLODNJE NA KLINICI ZA GINEKOLOGIJU I AKUŠERSTVO U NOVOM SADU.

Introduction Infertility affects 15-17% of reproductive age couples in our country, and 10-15% of couples worldwide. The aim of this paper was to present results and experience gained after the first 1000 cycles of the national In Vitro Fertilization (IVF) program, to offer professional standard of work in our country and to compare it with results obtained in Europe and worldwide. Material and methods The study prospectively included 1000 women who had undergone national In Vitro Fertilization program from October 2006 until November 2009 at the Department of Gynecology and Obstetrics, Clinical Center of Vojvodina, Novi Sad. Results The analysis included 1000 in vitro fertilization cycles. Male factor infertility was the leading cause (56.9%) followed by tubal factor (45.9%). The classic method of in vitro fertilization constituted 72.3% of all cycles, while intracytoplasmic sperm injection (ICSI) method was used in 27.7% of all cycles. The average number of embryos transferred was 2.67. The cycle cancellation rate was 14.10% and the aspiration rate was 94.40%. The clinical pregnancy and live birth rate were 33.41% and 26.78% per embryo transfer, respectively. Discussion and conclusion The results in our study showed that in our setting there are far less intracytoplasmic sperm injection cycles compared with the European average of 66.5% of all fresh cycles, and that we transferred more embryos on average. Our success rates are comparable with those in other European countries where the clinical pregnancy rates per aspiration and per transfer for in vitro fertilization were 29 and 32.4%, respectively in the period of observation. For intracytoplasmic sperm injection, the corresponding rates were 29.9 and 33%. [ABSTRACT FROM AUTHOR]
