Folate helps keep sperm normal:

Vitamins known as folates that prevent brith defects when consumed by women also help to keep men’s sperm normal,researchers reported.Men who took folic acid supplements and who ate folate-rich foods such as leafy greens had fewer abnormal sperm,the team at the University of California,Berkeley said.Specifically,the men had fewer abnormal sperm in which a chromosome had been lost or gained,known as aneuploidy,they reported in the journal Human Reproduction."We found a statistically significant association between high folate intake and lower sperm aneuploidy," said Brenda Eskenazi,who helped lead the study.
