Immunological consequences of vasectomy and vasovasostomy in XXXX .

The effects of circulating antibodies on fertility after vasovasostomy was studied in @entity2608 . After vasectomy there was rapid rise in antibody levels against @entity12179 ; these reached a peak after 2 weeks, rather more rapidly than has been reported in man. Antibody levels declined after this period. Monkeys with high antibodies were also more likely to have @entity738 and @entity292 . After vasovasostomy several monkeys became fertile again with sperm counts in ejaculate reaching a high level at 3 months, although levels were lower than before vasectomy. Some males retained a high and sustained level of sperm immobilizing antibodies in plasma, sometimes for 18 months or more. These males produced fewer @entity12179 and were more likely to be subfertile or infertile after vasectomy. Almost all the monkeys without antibodies were fertile. Presence of antibodies at vasovasostomy was not a definite indication of subsequent @entity249 but did provide an indication of likelihood of continuing sterility. These are similar to observations of @entity1 undergoing vasectomy and vasosostomy.
