Why doesn't the March of Dimes publicize the risk of birth defects from older fathers sperm mutations?

Question

Why only is the age of the mother and the health of the mother discussed? It has been shown that sperm can be damaged by alcohol, cigarette smoke, herbicides, and just by spontaneous mutations because they divide so many times and so many mistakes are made and as a male ages the mistakes are not gotten rid of. If the March of Dimes won't publicize this who can?

Sorry for such a rambling question but this is serious.

At t puberty a males sperm has dividesdover 100 times and at the age of 50 over 800 times. " The human mutation rate for base substitutions is much higher in male than in females and increases with paternal age. This effect is mainly, if not entirely due to the large number of cell division in the male germ line." James F. Crow professor emeritus of Genetics University of Wisconsin.

Answer 1

It is not only older men's sperm. If anything is ever wrong with a child it is always blamed on the mother or it is nobodies fault. A mans lifestyle is never considered unless both parents cannot conceive. If a mans is a heavy drinker, smoker, drug user nobody even thinks twice but let a woman have ever done those things and oh my God. I have always firmly believed that the lifestyle, etc. of a man strongly influences his sperm and future complications of a fetus, just as a woman's lifestyle does. Seems to me men get away with alot. If a man leaves his family, does not pay support, or does not even claim his kids then no big deal but let a woman do those things and she should be hung from nearest tree. Think about it, if a woman has a miscarriage the first thing she says is what did I do wrong and if she has multiple miscarriages then it is assumed she cannot carry a child for some reason nobody even considers that there may be some defect in her husbands sperm that is actually causing the miscarriages.

Answer 2

Because if sperm isn't healthy, it's not going to fertilize the egg. The chances of healthy sperm getting to the egg are slim enough; an unhealthy one doesn't have a snowball's chance in hell. Men release millions of sperm to fertilize a single egg; a woman's body is a hostile environment for sperm. Besides, sperm damaged in such a way are deformed, not mutated. Sperm alone doesn't divide, it's single celled. It is only after union with the egg that there is any dividing and if something goes wrong at that point, growth ceases and the embryo will die. The body will then proceed to break it down and flush it out. Men can be fertile with perfectly healthy sperm well into their 70s; unlike women, the male body makes the sperm, while females are born with all the eggs they'll ever have.
Do you have any idea the number of idiots being hired as professors at universities these days? I wouldn't be so quick to believe them.
