Does the Biological Clock Toll for Men Too?

Question

Answer 1

Absolutely, just like there is increased risk for older mothers in having children at older ages (Down's Syndrome risk in children increases dramatically with mother's age for example), the same thing holds true for fathers.

Remember that germ cells are created during our DEVELOPMENT, and remain in tact in our bodies until there are no more left (in females this is menopause).

Answer 2

not to the same extent

a man can father a child at any age - although it does get harder as he gets older!

a woman obviously goes through menopause around 50-60 and can not mother a child other than artificially at that stage

Answer 3

ur question is very vague

bio clock as in we sleep when its dark and function during light....
or as the other suggest... to do with a sort of male menopause???

yes males have a daily bio clock but no we do not have a bio clock on "sexual reproduction"!!!!!!

with time the ability of DNA to replicate diminishes and the male sperm quality diminishes but this is a time factor, not a clock....
....sound silly....????

females reach an age when they stop releasing eggs which is a factor of their bio clock

males never stop producing sperm (proves no bio clock) but due to DNA misreplication over long periods the chances of fusion wuth a female egg (regardless of age) decrease.

this is not a bio clock but more a degradation of genetic info
