先天性精管欠損症の3例

Abstract

Three cases of congenital absence of the vas deferens were found out of 197 males who visited the Department of Urology, Osaka Medical College complaining of male infertility during the past three years, from April 1972 to March 1975. Case 1 was complete absence of the left vas deferens and seminal vesicle, and the histological finding of testicular biopsy was normal spermatogenesis on the left side and germinal cell aplasia on the right side. The crossed epididymovasostomy was performed. Case 2 was incomplete absence of the right vas deferens (aplasia only in the pelvic portion), and the histological finding of testicular biopsy was normal spermatogenesis on the right side and hypospermatogenesis on the left side. The crossed vasovasostomy was performed. Case 3 was bilateral absence of vas deferens with cystic dilatation of the epididymis on both sides. Artificial insemination was performed six times for six months. The semen used in this case was mixed fluids which was collected by puncture of the epididymis and masturbation. In these three cases, the pregnancy was not achieved.
