High cholesterol one source of infertility in men

A study published in the open access journal PLoS One this week suggests high dietary cholesterol may contribute to reduced sperm viability and motility in men.  Ouvrier et al. found that mice with lipid processing disorders fed diets high in cholesterol had significantly less fertilizing potential than mice on a lower cholesterol diet.  These data may translate to men with dyslipidemia or older men attempting to conceive.
