0

OBJECTIVE: To review the practice in two hospitals with differing protocols in the timing of seminal analysis after vasectomy. PATIENTS AND METHODS: The results from 245 vasectomies carried out at Hospital A, where semen was assessed 3 months after vasectomy, were reviewed and compared with those from 100 consecutive vasectomies at Hospital B, where semen was assessed 6 months after vasectomy. The results of seminal analysis at Hospital A were also audited after changing to the 6-month protocol. The patients’ preferences for the timing of seminal analysis were also obtained. RESULTS: Of the 245 patients at Hospital A, 58 (24%) failed to provide samples, leaving 187 (76%) for evaluation; 528 samples were examined (mean 2.8 per patient, range 1-13). The first sample was positive in 36 (19.3%) and the second positive in 10 (5.3%), the first being negative. Four (2%) patients had persistent spermatozoa at 6 months, one subsequently undergoing exploration. Thirty-one (17%) patients provided
