title: [Clinical and statistical studies on male infertility and follow-up studies for pregnancy (II)].
abstract: Clinical and statistical studies were carried out on 369 infertile male patients who are increasing year by year visiting our clinic during the 3 years from January 1978 to December 1980. If divided into 5-year age groups, the highest frequency occurred in the 30 to 34 year-old age group. In the semen analysis, 23.8% of the patients showed azoospermia, and 48.5% oligozoospermia; the testicular volumes of these patients was generally small. Pathological examinations of their testis revealed germinal cell aplasia or hypospermatogenesis. In the hormonal examinations performed, serum LH and FSH levels in azoospermic and oligozoospermic patients showed a tendency to be higher than normal. Follow-up studies for pregnancy were performed on 242 cases. Among the 108 cases which we were able to study, 30 cases were able to give successful pregnancy, 17 of whom had been treated by clomiphene citrate, 2 by testosterone-clomiphene therapy, and 11 were untreated.
