This just in! Men have biological clocks.
A recent study from Eylau Centre for Assisted Reproduction used the data from 21,000 Intrauterine Inseminations (IUIs) to put to rest the age old question of age old dads. The silver haired stags are not as virulent as their sportscars would make them out to be. In fact, men over the age of 40 are less likely to impregnate and more likely to have a miscarriage.
Men keep producing sperm into old age, but they produce less sperm and more of them have damaged DNA – as you might expect from the liver spotted teethless set.
Women are slightly different in that they have about 400 eggs culled from the thousands of available oocytes, and these eggs are gradually flushed out post-ovulation during the menstrual process. Overtime the stockpile of dormant eggs are unable to repair themselves, and thus are subject to chromosomal abnormalities. Older moms too are just as likely to be infertile, have miscarriages, or children with genetic abnormalities.
I’m rather surprised that this is news. Only a month ago, I wrote about how children of older Dads were dying more frequently due largly to their genetic abnormalities. This latest research only confirms previous reports that older Dads have a whole host of problems when it comes to reproduction.
So, be careful, older dudes, when planting seeds in your lady’s fertile crescent. You might want to stick to racing around on your rascal scooter and offering butterscotch to the boy who delivers your paper.
