Introduction: Male infertility is currently a leading indication for cycles of assisted reproduction. The cause is multifactorial in origin. Material and methods: Possible causes of male infertility can be identified with thorough differential diagnostics. In case of ineffective therapy of identifying the cause of male infertility or idiopathic male infertility the techniques of assisted reproduction are indicated. Results: Success of assisted reproduction cycles is decreasing with increased severity of male infertility. The pregnancy rate in oligoasthenoteratozoospermia under 5mil/ml was 45 %, under 1 mil/ml was 34 % and in azoospermia 32 %. Conclusions: In cases of the most severe male infertility the higher pregnancy rates are reached by assisted reproduction techniques than in spontaneous conception in the healthy couple in one cycle (fecundability according to Guttmacher 20-25 %).
