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.<\/jats:p>","DOI":"10.1136\/bmj.291.6510.1678","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T11:00:59Z","timestamp":1238670059000},"page":"1678-1680","source":"Crossref","is-referenced-by-count":90,"title":["Testicular vein ligation and fertility in men with varicoceles."],"prefix":"10.1136","volume":"291","author":[{"given":"H W","family":"Baker","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H G","family":"Burger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D M","family":"de Kretser","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B","family":"Hudson","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G C","family":"Rennie","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W G","family":"Straffon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1985,12,14]]},"reference":[{"key":"ref_1","first-page":"293","article-title":"Varicocele and the pathogenesis of the associated subfertility.
