Results of investigations on seminal fluid in so-called oligospermiogenesis

Diagnosis of ligospermiogenesis was made in 76 infertile subjects submitted to testicular biopsy. Histological examinations demonstrated a reduction in mature spermatids (Sc. Sd.-Clermont classification) in the tubular sections. Comparison of histological data with findings from seminal fluid analyses in these subjects revealed: a) a pathological seminal fluid pattern in all cases of oligospermiogenesis, b) these patients may show either an azoospermic or oligozoospermic seminal fluid pattern; statistical analyses confirmed an almost equal distribution of the two conditions.
