Subject: Old sperm (For Terry)

Terry, I think it is because sperm competes and that the undamaged ones
make it. Eggs in a woman do not compete.

"Actually, we don't know that babies born of older fathers are
"perfectly
normal."  It is actually well known that just as children born of older
mothers have a greater chance of being born with  genetic defects
(Down's
Syndrome being perhaps the most common), so, too, do babies born of
older
fathers have a higher incidence of genetic diseases.  I stick to my
original position.  It makes sense to consider cryopreserving a sample
of
tissue today for possible use in the future.
