[Clinical study of male sterility patients]

We report the results of a clinical study of the male sterility in our institute during the past 55 months. A total of 187 male patients consulted us with the complaint of sterility, and the semen of 173 patients was examined, sixty two cases were diagnosed as azoospermia, 34 as severe oligozoospermia, 17 as moderate oligozoospermia and 60 cases as normospermia. Based upon the results of semen examination, endocrinological examination and so on, 78 cases were diagnosed as idiopathic spermatogenetic dysfunction. Serum follicle stimulating hormone (FSH) levels in azoospermia patients were significantly higher than those of normal males statistically, and the serum FSH level was considered to correlate with the damage of spermatogenesis. We performed serial treatment using kallikrein and/or human chorionic gonadotropin, on 44 patients. Only patient, who was treated with a high dose kallikrein, succeeded in impregnating his spouse. Four of our patients with oligozoospermia had received chemotherapy for testicular cancer. Recently, with the progress of anticancer chemotherapy, curative cases have increased gradually. However, because of adverse reaction, oligozoospermia cases have also increased. Considering the quality of life, the management of the sterility may be very important.
