RESUMO
There were 122 infertile males who received testicular biopsy in our department during the period from 1978 to 1980. Among them, 20 patients were diagnosed to have Sertoli cell only syndrome by pathologic finding. A cumulative clinical investigation was undertaken in 20 patients with Sertoli cell only syndrome using history taking, orchidometer, semen analysis, and plasma hormonal assay (FSH. LH, & Testosterone). We found the interesting relationship between the size of the testis and plasma hormonal levels. 1. In pathologic finding, Sertoli cell only syndrome was 16%, spermatic arrest 16%, hypospermatogenesis 15%, peritubular fibrosis 15%, and normal testis accompanying obstruction of efferent duct 22%. 2. The size of the testis was average 12ml, and plasma FSH was increased to average 27.43 IU/L, plasma LH was also increased to average 25.9 IU/L, but plasma testosterone was within normal ranges (average 5.58 ng/ml).
