The article also talks about how surgical repair may not significantly improve pregnancy rates. However, the article also discusses some flaws in this analysis. Read more:
Surgery for Male Infertility Ineffective
But Backers of Varicocele Repair Disagree

From the article:
"Varicoceles are enlargements of veins inside the scrotum that drain the testicles. These enlargements may lead to a rise in temperature and a decrease in blood circulation through the testes, and can hurt sperm production. But their exact role in male infertility is not known.
As many as 15% of all men are believed to have varicoceles. But up to 40% of infertile men have them.
In this review, researchers reanalyzed data from seven previously published trials assessing the impact of varicocele repair on pregnancy rates. There was a 1% improvement in pregnancy rates among the partners of men who had varicocele repair, compared with men who received no treatment. The findings are reported May 31 in The Lancet.
"There does not seem to be any value in doing [varicocele repair] as far as fertility is concerned," analysis co-author John A. Collins, MD, of Ontario's McMaster University, tells WebMD. "There is just very little evidence suggesting that it is effective."
