Abstract
The aim of our study has been the complete andrological and endocrinological evaluation of seven cases of bilateral ductus deferens agenesia. In all cases testicular biopsy demonstrated a normal spermatogenesis. Urographic examination showed, in four cases, the existence of congenital anomalies of the urinary tract. The presence of spermioagglutinating and spermimmobilizing antibodies in blood and in seminal plasma was excluded in all cases. Basal and stimulated levels of FSH, LH, PRL and testosterone were within normal limits. Surgical exploration of seminal tracts and bilateral collection of sperm at the caudal portion of the epididymis appear to be mandatory in order to select the cases for surgical therapeutic approach.
