Objective: To analyze different factors influencing positive pregnancy rate (PPR) and live birth rates (LBR) following in vitro fertilization (IVF). Materials and Methods: Between January 2009 and December 2015, a total of 1,451 embryo transfer (ET) cycles were performed at the Fertility Unit at Jordan University Hospital. Only the first fresh cycles (1,025) were included. Data were collected from the unit registry. Results: PPR was achieved in 44.3% (n=454) of cycles, while live birth rate was 36.9% (n=378). PPR and LBR in women younger than 35 years of age was 47.5% and 33.5, respectively. In women aged 35-39 years, PPR was 27.6% while LBR was 15.6%, and for women older than 40 years PPR and LBR, it was 10.9% and 4.7%, respectively. Causes of infertility did not affect PPR or LBR. The maximum percentage of live birth was achieved when 11-15 oocytes were retrieved (39.4%) and when three embryos were transferred (36.9%). Live birth rate was not affected significantly by the number of embryos transferred. Conclusion: Women’s age is the main determinant of live birth rate after IVF. Cause of infertility did not affect live birth rate.
