Birth defects in sperm
Back to Genetics and stem cells. But this is an opinion piece. We don't know how the researchers selected the evidence they reviewed, and it is possible that not all relevant research was considered. The review should not be taken as firm evidence that there is such a thing as a "male biological clock" and fathers are putting their children at risk by delaying fatherhood until middle age. It may not boost your sperm's health, but it will definitely improve your health. Neither the Daily Mail nor The Times recognise the important limitations of this review: namely, that is it is not a systematic review , so it carries far less weight in terms of evidence.

Older fathers put health of partners, unborn children at risk
HealthDay —Having a low sperm count doesn't seem to determine whether a man's children will be born with birth defects, a new study indicates. With infertile couples , men are partially or fully responsible for the inability to conceive about 40 percent of the time. Assisted reproductive technologies such as in vitro fertilization can help couples have children, but research has suggested a possible link between these approaches—when used to treat infertility problems in the male partner—and a higher risk of birth defects. In the new study, researchers examined a Baylor College of Medicine database in search of possible connections between birth defects and low sperm count. The researchers didn't find any links.
Men should not smoke, drink or take unnecessary drugs if they are planning to become fathers to avoid causing health problems for their children, a health expert has warned. Scientists found that toxic chemicals can damage sperm, which then pass altered genes onto babies. In experiments on rats Matthew Anway of the University of Idaho found that some garden chemicals caused problems such as damaged and overgrown prostates, infertility and kidney problems, all of which were present up to four generations later. Cynthia Daniels, of Rutgers University in New Jersey, an expert in the relation between a father and child's health, said: "If I was a young man I would not drink beer, I would not be smoking when I'm trying to conceive a child.
