Microsurgical Vasovasostomy

Abstract

The physiologic effects of ductal obstruction resulting from vasectomy include dilation of the proximal or testicular end of the vas deferens. In the presence of normal spermatogenesis and without secondary epididymal obstruction, the diameter of the obstructed testicular end of the vas deferens can reach 1.0 mm. In comparison, the unobstructed abdominal segment maintains a diameter of 0.3 mm. Vasal reconstruction following vasectomy, therefore, involves the anastomosis of structures of widely differing dimensions.
