Study: Sperm Quality Deteriorates With Age
Posted on Jun 7, 2006
It apparently isn’t just women who have a biological clock.
It isn’t only women who face a ticking biological clock when planning parenthood.
New research has found that as men age, the quality of their sperm deteriorates, making it more likely they will have trouble becoming fathers and increasing the possibility of having a child with dwarfism.
The study, led by Andrew Wyrobek of Lawrence Livermore National Laboratory and Brenda Eskenazi of the University of California, Berkeley, School of Public Health, appears in this week’s online edition of the Proceedings of the National Academy of Sciences.
Women’s biological time clock has long been known, with older women having an increased risk of miscarriage and of producing children with genetic defects such as Down Syndrome.
