scienceclass#5 Old men make better babies!?

Since the beginning of mankind, women face the same problem of the `biological ticking clock´. "If you want kids, then its got to be while you are still under a certain age." girls have always been told.

This was not a random allegation; it was a grounded  conclusion made after years of experiences and observations. Scientific studies have justified those observations. Studies could show that with age, the fertility rate in women drops drastically. With 40-50 years old women having only a 35% chance of getting pregnant. Several studies have showed that with age, the rate of spontaneous miscarriages increase and genetic abnormalities arise. With the tremendous progress in medicine and the pronounced prenatal care, the proposed age limit has been rising. From 25, 30,40 and of to-date 45-50 year old women getting babies isn't a scarcity anymore. 

Has mother-nature spared men even this trouble too!?

Men have no `biological ticking clock´, at least that's what they believe. They produce 100-200 millions sperms daily. So we think as long as they can physically operate, then Alles ist in Butter.

But how are these children that older men make? Are they better than those made by younger men?


Studies have shown that children of older men live longer. Researchers were able to link this observation to the length of the telomeres. Telomeres are caps on the ends of chromosomes. The more a cell divides the shorter the telomere becomes and as the telomere shortens, the cell ages. Surprising was the fact that this did not apply to the sperm. To the contrary, the telomeres of the sperms were longer with age.

Other studies shown that children whose father and grand father lived to older age, also lived longer. Since the older men are old, their children tend to live longer. Furthermore, older men  know their medical conditions. Genetic dispositions of chronic diseases like diabetes and hypertension can be passed on to the offspring. These are diseases which manifest themselves at older ages. Healthy older men might have lower chances of passing these genes to their kids.

But wait a minute not so fast; is it all really that good?

Sorry pals, but no! Older fathers aren't doing their children any good. A longer life, maybe, but what kind?
Spermatogenesis (the process which produces sperms) takes place through out a mans life, unlike oogenesis (the process which produces the egg) which is almost complete at birth. This means that sperms undergo cell division at older age and this leads to a  higher  mutation load. This means that babies made from this sperm suffer higher risks for genetic disorders like down syndrome, autism and many neurological disorders.

Just like women older men show lower fertility rates and increased miscarriage risks no matter how old the woman is.

Another study (no kidding)... showed that older men make ugly babies (...yes, researchers are crazy people).

So in case you don't want longer living, genetic-mutated and ugly babies, better get started with the making before your good years are gone :-).

Stay all blessed,

Lots of luv

However, the researchers noted that an older age of fatherhood also brings risks for the children — studies have shown that older fathers may be at more likely to pass down certain genetic mutations, which may increase the risk of miscarriage or certain diseases. Studies have also found children of older fathers are more likely to be diagnosed with neurological conditions such as autism. - See more at: http://www.livescience.com/20884-delayed-fatherhood-children-telomeres-lifespan.html#sthash.rJOGz6tc.dpuf

n most cells, telomeres get shorter with age, but in sperm cells, they get longer, the researchers said. When men delay having children, those longer telomeres of their sperm cells may be passed on to the next generation. Moreover, the effect appears to be additive across generations, the researchers said.
The findings suggest that being born into a lineage in which the males reproduced at later ages has health benefits, said study researcher Dan Eisenberg, a doctoral researcher in anthropology at Northwestern University.
