To determine the factors which might affect the recovery of fertility after an accurate microsurgical vasovasostomy, we conducted α 3-year-follow up study in 56 men after microsurgical vasovasostomy. Twenty-two variables as putative factors associated with recovery of fertility were measured. The results of Logistic regression and other statistical analyses suggest that 8 factors including age of husband, age of wife, history of past pregnancies of current wife, number of vasovasostomies, serum FSH, LH and T before vasovasostomy, and sperm granuloma of vas nodule are of no significance in recovery of fertility, whereas 14 factors including years after vasectomy, sperm concentration, progressive motility, sperm motility, viability, normal morphology, sperm-egg penetration rate, TAT and SIT before-and-after vasovasostomy, MAR, IBT adherent IgG and IgA after vasovasostomy are significantly associated with repregnancy.
