Abstract

A light microscopic study of testicular biopay specimens from 141 cases of azoospermia. during a period of 1975 to 1977 at Seoul National University Hospital was performed. These were classified into normal or essentially normal (29 cases). hypospermatogenesis (4 cases), complete fibrosis (12 cases), incomplete fibrosis(38 cases), germ cell aplasia (33 cases), maturation arrest (Bcases), cryptorchidism (16 cases) and Klinefelter syndrome (1 case). The frequency distribution of the three main histological groups was incomplete fibrosis 26.996, germ cell aplasis 23.4%, and normal or essentially normal 20.6%. The much higher incidence of incomplete fibrosis was assumed to reflect the use of stricter criteria for azoospermia or geographical difference.
