Smoking health hazards may pass on to descendants
June 30th, 2007 by Nina Thompson, ARNP
Some men say they’ll quit smoking after their child is born, a new study indicates a good reason to quit well in advance of trying to conceive. The findings of this recent study suggest that the consequences of smoking extend beyond the smoker to their nonsmoking descendents. While it has long been known that smoking causes DNA damage, this study is the first evidence that tobacco actually causes inheritable male mutations in the sperm. If inherited, these mutations persist as irreversible changes in the genetic composition of offspring.
