Abstract
Pregnancy rates in 651 subfertile couples in which the man had a varicocele were analysed by life table methods and were not found to be significantly different before and after testicular vein ligation performed in 283 patients. Estimated proportions of couples conceiving were roughly 30% by one year and 45% by two years in both groups. The operation was also not associated with improvement in results of semen analysis. These findings suggest that testicular vein ligation for varicoceles does not improve fertility.
摘要
采用寿命表法分析了651对男性患有精索静脉曲张的不育夫妇的妊娠率，结果发现，在283例患者接受睾丸静脉结扎术前后，妊娠率并无显著差异。两组中，估计一年左右受孕的夫妇比例约为30%，两年左右受孕的夫妇比例约为45%。该手术也与精液分析结果的改善无关。这些发现表明，精索静脉曲张的睾丸静脉结扎术并不能提高生育能力。
