ABSTRACT
PURPOSE: The purpose of this study is to evaluate the preoperative factors that influenced postoperative sperm concentration after vasovasostomy. MATERIALS AND METHODS: We retrospectively reviewed 97 consecutive single-layer vasovasostomy procedures performed by a single surgeon between March 2003 and September 2010. The patients were stratified into three groups based on sperm concentration at 1 month follow-up: group I-azoospermia, group II-oligospermia, and group III-normal. We evaluated the preoperative factors that may have influenced sperm concentration at postoperative 1 month. Patients with serial semen analysis were divided into four groups according to the change in postoperative sperm concentration at the 6-month visit: group II-N-from oligospermia to normal, group II-O-from oligospermia to oligospermia, group III-O-from normal to oligospermia, group III-N-from normal to normal. We compared the pregnancy rate among the four groups. RESULTS: The mean obstructive interval was 9.69 years in group I, 6.02 years in group II, and 7.82 years in group III. There were significant differences found among the groups (p=0.035). There was significantly different change in sperm concentration, sperm motility, and sperm morphology between each of the groups. A total of 32 patients underwent serial semen analyses at 1 month, 3 months, and 6 months after vasovasostomy. There was no significant difference in patient age, obstructive interval, or follicle-stimulating hormone among the groups. The natural pregnancy rate in group II-O was lower than that in group II-N, and in group III-O was lower than that in group III-N. However, there was no significant difference among each of the groups. CONCLUSIONS: The sperm concentration after vasovasostomy was significantly related to the obstructive interval between vasectomy and reversal.
