Decreases in Human Semen Quality with Age Among Healthy Men.

DE2004802878

Publication Date	2001
Personal Author	Eskenazi, B.; Wyrobek, A. J.; Sloter, E.; Kidd, S. A.; Moore, L.; Young, S. S.; Moore, D.
Page Count	36
Abstract	The objective of the report is to characterize the associations between age and semen quality among healthy active men after controlling for identified covariates. Ninety-seven healthy, nonsmoking men between 22 and 80 years without known fertility problems who worked for or retired from a large research laboratory were studied. In a group of healthy active men, semen volume, sperm concentration, total sperm count, and sperm motility decrease continuously between 22-80 years of age, with no evidence of a threshold.
