You claim that Junior is giving you gray hairs, but is he really? In actuality your kids may be adding years to your life — one recent study suggests that fatherhood may actually reduce a man’s risk of dying from a heart attack.The study, which was conducted last year and led by Michael Eisenberg at Stanford and Mark Pletcher at the University of California, San Francisco, addresses the relationship between heart health and fatherhood. Nearly 138,000 men between the ages of 50 and 71 participated in the study, which used data from the NIH-AARP Diet and Health Study, a national survey in retired persons. Only men free of heart disease and stroke at the beginning of the study were included, and the heart health of these individuals was followed for over ten years, on average. After adjusting for income, education, health habits, and age, men without children died from heart disease 17% more frequently than men who were fathers.
One possible explanation for this heart health discrepancy is a difference in testosterone production. Studies have shown that low levels of androgen hormones, such as testosterone, result in both a higher risk for cardiovascular disease and for infertility. The correlation between lower testosterone and infertility may partially explain the higher rate of cardiovascular death observed in childless men.
