Abstract:The results of in-vitro fertilization in natural cycles (NIVF) in women with tubal infertility at our department are presented. The study had a prospective design. We needed 75 cycles in 50 patients to obtain one oocyte from each patient. Successful oocyte recovery rate was 67% per started cycle and 82% per oocyte retrieval. Thirty-five embryos were transferred and resulted in four ongoing pregnancies (5.3% per cycle, 6.5% per oocyte retrieval, 11.4% per embryo transfer and 11.4% per embryo). Six patients who participated in the study made a second attempt at NIVF. Five of them conceived of which four were ongoing. Cumulative ongoing pregnancy rates are 9.8% per cycle, 11.9% per oocyte retrieval, 19.5% per embryo transfer and 19.5% per embryo. We conclude that NIVF is an easy, cheap and realistic method to obtain a pregnancy for patients with tubal infertility.
