This is the first of four recent article or TV spots on this vitally important topic.
Here are some extensive excerpts:

.............."Several studies have found that older fathers risk having children with medical problems, including Down syndrome. Fisch and his colleagues evaluated more than 3,400 cases of Down syndrome, finding that if the woman and the man were both over age 35 at the time of conception, the father's age played a role in prevalence of the disorder. This effect was most pronounced when the woman was over 40, the researchers found. And, in those cases, the incidence of Down syndrome was about 50 percent attributable to the sperm, the researchers said. The study was published in 2003 in The Journal of Urology.

In another study, Dr. Avraham Reichenberg, of Mount Sinai School of Medicine in New York City, found that advanced age for fathers is associated with an increased risk of autism. His team gathered data on the age of fathers of more than 318,000 people born in Israel during the 1980s. The researchers found that the chances of having a child with autism or a related disorder were about six times greater if the father was 40 or older, compared to men 29 or younger. The findings were published in the September 2006 issue of The Archives of General Psychiatry.

Still another study found that the risk of schizophrenia in children was tied to older age of the father. In the study, which included about 90,000 people, the researchers discovered that children whose fathers were 50 or older when they were born were nearly three times more likely to have the disorder than those born to younger fathers. That study was published in 2001 in The Archives of General Psychiatry.

Another study, published in 2002 in Human Reproduction, found a higher risk of miscarriage in mothers 35 and older and fathers 40 and older.

And, in 2004, The Journal of the American Medical Association reported that 20 different disorders in children, ranging from schizophrenia to skeletal disorders, have been linked to the advanced age of the father......................
