- Seventeen patients with congenital agenesis of the
vas deferens, 9 per cent of 188 azoospermias due to
epididymal obstruction, were investigated in tbe
department of urology for the past 16 years, These
anomalies were confirmed by surgical explorations.
All the patients were married for 4 years with
range from 1 to 15 years. Age of patients ranged
from 27 to 41 with the mean of 31 and that of their wives ranged from 23 to 34 with the mean
of 28. Sexual coitus per week ranged from I to 6
with the mean of 2.5. They were consisted of 14
patients with bilateral agenesis of vas deferens and
3 patients with unilateral agenesis. Associated absence
of epididymal body and/or tail was found in 52 per
cent of a total of 31 anomalies of vas deferens.
Spermatocele was not found in epididymal head.
Tubular dilatation of the epididymis was seen in 6
out of the 31 epididymal head. The histologic
examination of the testes showed normal spermatogenesis
in the most of the cases. In two patients with
unilateral agenesis of vas deferens, the obstructive
lesions of epididymal tails of contralateral side were
corrected by side to end anastomosis of epididymal
head to vas deferens under surgical microscope.
The result were successful in one patient of them.
For the other patients, the implantation of alloplastic
spermatocele should be considered. In conclusion,
the results of this clinical investigation emphasizes
the importance of careful scrotal examination in the
diagnosis of an infertile male patient and In the
preoperative check of vasectomy operation.
