Often the greatest concern with respect to<unk>  is its effect on male fertility. The relationship between<unk>  and infertility is unclear. Some men with the condition are fertile, some have sperm that are normal in shape and move normally but are compromised in function, and some have sperm with abnormal shapes or that do not move well. Theories as to how<unk>  affects sperm function include damage via excess heat caused by the blood pooling and oxidative stress on sperm. Tobacco smoking and mutations in the gene expressing glutathione S-transferase Mu 1 both put men at risk for infertility; these factors may also exacerbate the risk that<unk>  will affect fertility.
