Abstract
From 1991 to February 1994 we observed 40 patients affected by azoospermia. The reasons for azoospermia were various: contraceptive vasectomy 2 patients, deferential agenesia 2 patients, bilateral testicular hypotrophy 12 patients, specific and aspecific infections 8 patients, hypogonadotropic hypogonadism 1 patient, Klinefelter syndrome 1 patient, 5 patients had severe oligoastenospermia (< 5 mil/ml) with mono and bilateral epididymal cysts connected with left varicocele in one patient. 9 patients with azoospermia had II and III degree varicocele. In 5 patients recanalization was carried out: epididymovasostomy in 2 cases (1 laterolateral and 1 terminoterminal) and vasovasostomy (3 cases). In the 2 patients who underwent microsurgical epididymal sperm aspiration (MESA) we took from 12 to 38 millions of spermatozoa. 40 days after the recanalization, spermatozoa appeared in the semen of all the patients. In the azoospermic patients affected by varicocele who underwent venous reflux correction, no spermatozoa were found after 18 months. Only a few azoospermic patients (12.5%) could undergo the recanalization treatment.
