WHO: Boost SARS Surveillance

JAMA. 2003;289(22):2929. doi:10.1001/jama.289.22.2929-a

A new study by researchers in the Netherlands and Canada has found that a common treatment for impaired fertility in men appears to be largely ineffective (Lancet. 2003;361:1849-1852).

Up to 15% of men are believed to have varicoceles, dilated veins in the scrotum that can cause testicular damage and result in decrease quantity and quality of sperm. Although its efficacy has not been clearly demonstrated in clinical trials, varicocele repair is a widely used treatment in men with impaired fertility.
