We determined the incidence of sperm in the ejaculate before vasectomy reversal, and correlated this result with intraoperative and postoperative findings.
Before vasectomy reversal semen was analyzed and granulomas were palpated in 186 men. The results were correlated with intraoperative vasal fluid and postoperative semen analyses.
Of 18 men (9.7%) with sperm present in the pre-reversal analysis 94% had sperm in at least 1 vas intraoperatively. The presence of palpable granulomas at the vasectomy site did not correlate with either pre-reversal or post-reversal semen analyses, or the presence of sperm in the vasal fluid intraoperatively.
Sperm are present in 9.7% of pre-reversal ejaculates and predict sperm in at least 1 vas intraoperatively. These findings also suggest the possibility of late vasectomy failures.
我们测定了输精管复通术前射精中精子的发生率，并将该结果与术中及术后的发现相关联。
在186名男性进行输精管复通术前，对精液进行分析并触诊肉芽肿。将结果与术中输精管液及术后精液分析相关联。
在复通术前分析中存在精子的18名男性（9.7%）中，94%在术中至少一侧输精管中有精子。输精管结扎部位可触及肉芽肿与复通术前或术后精液分析，或术中输精管液中精子的存在均无关联。
9.7%的复通术前射精中存在精子，且可预测术中至少一侧输精管中有精子。这些发现也提示了输精管结扎术后晚期失败的可能性。
