I really did not know this, and I'm happy to read it (if that doesn't sound too cruel!). I thought it was just we ladies who [alledgedly] started to tick, tick, tick after a certain period of time. Interesting.
Scientists say they have found more evidence that men as well as women have biological clocks and that they start to tick in their mid-30s.
A French study of over 12,200 couples having fertility treatment suggests the chance of a successful pregnancy falls when the man is aged over 35.
It adds that the chance is significantly lower if he is over 40.
Previous studies have shown that both natural and assisted conception is more difficult if the man is over 40.
The researchers told a European reproductive health conference that it was likely the problems were caused by DNA damage in sperm.

This is the tip of the iceberg about the male biological clock. A great deal of non-familial autism, schizophrenia, type 1 diabetes, MS, Alzheimer's, many single gene disorders are formed de novo but an older father's sperm. Unfortunately the public is not currently well informed. Here are some links for anyone interested in further studies, there are lots: http://www.sciam.com/article.cfm?id=fact-or-fiction-men-have-biological-clocks
