Men’s health is in many ways linked to women’s health. While the life expectancy gap between men and women has decreased, it's no secret that men still need to pay more attention to their bodies. Several things work against men. They tend to smoke and drink more, and they don't seek medical help as often as women.
There are various reasons why couples may wish to conceive either a baby boy or a girl. Family balance or societal pressures are some of the reasons. Rarely, there may be a medical reason why a child of a particular sex is desired. But sex selection purely for social reasons has ethical and demographic dilemmas, and is medically illegal in many jurisdictions.
How old a man is when he has children may affect the lifespans of his grandchildren, a new study suggests.
Men in the study who were older when they had children tended to have kids and grandkids with longer telomeres — caps on the ends of chromosomes that protect the chromosomes from damage.
The optimal fertility window for both women (and men) is narrow, and shrinks exponentially with advancing age. Pregnancies are best planned when fertility rates are highest, couples are in optimal health, and when chances of delivering a healthy baby are highest. Biologically, the optimal age bracket for the best fertility outcomes spans from the mid-20s to the mid-30s.
