Summary
Vas deferens anastomosis was carried out in 50 cases. The different histological findings
noted are normal histology, sloughing and disorganisation with active spermatogenesis,
hypospermatogenesis, Leydig cell hyperplasia, focal atrophy of tubules, peritubuler
thickening. extravasation of spermatozoa spermatogenic maturation arrest and sertoli
cell only pattern (Table II). Surgical success was 94.8%, and pregnancy rate, 63.2%.
The high percentage of successful reanastomosis of vas is likely to enhance the acceptibility
of vasectomy as a method for family limitation and population control. Hcwever the
relatively fow pregnancy rate in spite of high surgical success requires further investigation.
