Abstract
Sperm agglutinins emerging from the reopened part of the vas deferens were found in the seminal fluid of 10 out of 29 men after vasovasostomy. There was a strong association between the presence of these antibodies and the failure to impregnate over a period of 14 to 33 months. Of 20 couples, 11 pregnancies resulted among the 13 women whose men had no sperm agglutinins in the seminal fluid, but only 1 among the 7 whose men had such antibodies, 2p = 0.0044. The presence of sperm agglutinins in the seminal fluid was always associated with their presence in the serum, usually in a higher titre. Preoperative serum levels thus are highly predictive of ability to impregnate after reversal of vasectomy.Entities:
