Comparison of in-vitro fertilization in male and tubal infertility: a 3 year survey*

Abstract

The in-vitro fertilization and embryo transfer (TVF-ET) procedure was compared in 175 couples with male infertility and 480 couples with tubal infertility. In cases of male infertility, more oocytes were recovered but fewer oocytes were fertilized. Although the cleavage rate was decreased, no difference in embryo quality was found. In male infertility, fewer transfers were performed and the average number of embryos per transfer was lower. The total pregnancy rate was also lower per cycle (12.8 versus 22.9%), but not per transfer (25.4 versus 25.7%). The further obstetrical outcome was similar in both groups. We conclude that male infertility can be treated by IVF-ET but results are still disappointing when compared to a control group with normal spermatozoa.
