[Analysis of 830 case histories of male sterility of which 282 are usable. Results of our diagnostic investigations and therapeutic procedures].

Overall results are given of the investigation and treatment of 282 cases of male sterility: 245 cases of secretory and 37 of excretory sterility; 126 cases in which treatment produced no change, 110 cases showing biological improvement and 45 cases in which pregnancy occurred; 128 of the 282 men had varicoceles. There were three groups of patients; 1) Those with azoospermia: 59 cases, predominantly with excretory problems, bilateral atrophy and chromosomal anomalies: of these, eight showed an improvement, of which two resulted in pregnancy; 2) Those with oligo-asthenospermia: 110 cases, with predominantly solitary varicoceles, intoxications and unknown causes: 66 per 100 showed improvement, and in 23 of these cases pregnancy resulted; 3) Those with varicoceles associated with another cause, predominantly unilateral atrophy and intoxications: 62.8 percent showed biological improvement, and 12 of these cases resulted in pregnancy. Also mentioned is the group of patients with solitary asthenospermia; solitary oligospermia and hyperzoospermia of more than 200 million per ml. Varicocele is the predominant pathology in these three groups.
