Description

In 7 vasectomized patients, reanastomosis of the duct was performed under microscopic observation. The operative technique consisted of monolayer anastomosis by using 9-0 monofilament nylon with 8-12 stitches. The age of the patients ranged form 25 to 49 years old, with a mean of 41 years old. The periods from vasectomies to the operation ranged from 4 months to 19 years, the mean being 9 years. The reason for which vasovasostomy was hoped was improvement in illness of the wife and that in economical status in 1 case each. In all of the remaining 5 cases the reason was remarriage. In all but 1 case who had undergone the operation only 1 month before, pregnancy occurred (6 out of 6 cases or 100%). We considered that monolayer suturing is not inferior to double layer suturing which is employed in many institutes now. After the operation pregnancies followed from 2 months to 1 year and 1 month, the mean being 6 months. No correlation was seen between the time form vasectomy to vasovasostomy and that from vasovasostomy to conception. The testicular biopsies performed in 2 cases whose vasectomies were done 2 and 6 years ago revealed testicular score count as low as 6.7 and 6.6, respectively.
