[Intracytoplasmic sperm injection for treatment of male infertility].

The results of 84 consecutive couples who underwent 94 cycles of in-vitro fertilization (IVF) augmented with intracytoplasmic sperm injection (ICSI) were analyzed. Inclusion criteria were previous total failed fertilization or unsuitable sperm parameters for conventional IVF. The rate of diploid fertilization was 61,7%; the implantation rate per embryo was 12,0% and the ongoing pregnancy rate per transfer was 30,0%. None of the sperm parameters of the original or processed semen sample were correlated with ICSI outcome. Conversely, female age and basal serum concentrations of follicle stimulating hormone (FSH) had a significant impact on implantation and pregnancy rates. ICSI has become a very successful therapy in overcoming different types of male infertility.
