Actually with men, don’t the chances for having a child with Down’s Syndrome go up after age 40?
I believe that higher risk hits even earlier at 35.
A question, is it due to their older partners or them? You would have to look at rates per female partner as well. I don’t know if that has been done.
I read where the risk for autism increases significantly for men 45 and over.
No it is the Women.
No
This is a fembot canard
Men’s sperm deterioration is statistically insignificant
It exists but it is tiny

I have no knowledge of that.
Have you any data?
No.
“Actually with men, don’t the chances for having a child with Down’s Syndrome go up after age 40?”
the increase in risk to the fetus is almost exclusively with the female due to the complexity of replicating new eggs over the decades ...
the male sperm contributes only one set of chromosomes, whereas the female egg contributes one set of chromosomes plus the prototype for all cellular organelles and cell structures that all subsequent cells are patterned after ...
it’s always been an ignorant myth that the chromosomes contain ALL of the information necessary to make a new creature: perhaps even MORE information is contained in the structures of the egg itself than in the chromosomes ...
Don't all Democrats have Down's Syndrome.
A lot of conditions are associated with advanced parental age. Autism is another, as is ADHD.
