[Initial experience with the MESA and TESE techniques in the treatment of infertile men with azoospermia]

The authors evaluate their initial experience and results of the technique of microsurgical aspiration of epididymal sperm (MESA) and extraction of testicular sperm (TESE) combined with intracytoplasmic sperm injection into the oocyte (ICSI) in men with azoospermia. The above methods were used in 16 patients with repeatedly assessed azoospermia. Epididymal sperm was obtained in six instances, testicular sperm in 10 instances. With epididymal sperm after ICSI 50% fertilization was achieved after ICSI, with testicular sperm 51% fertilization of oocytes.
