Higher Testosterone Protects Older Men’s Hearts

Naturally occurring high testosterone can protect the heart of older men.

Findings published in the Journal of the American College of Cardiology showed that of 2,400 Swedish men in their 70s and 80s, those with the highest testosterone levels were less likely to suffer a heart attack or stroke over the next several years than men with the lowest levels

Low testosterone may be a marker of other health conditions that put men at higher risk of cardiovascular disease.


Testosterone Drops in New Fathers

It seems that women aren’t the only ones affected by hormone fluctuations during child birth. Fatherhood, it seems, also comes with physiological changes.

A new study reveals that testosterone levels drop when men become fathers.

The study, experts say, suggests that men’s bodies evolved hormonal systems that helped them commit to their families once children were born. It also suggests that men’s behavior can affect hormonal signals their bodies send, not just that hormones influence behavior. And, experts say, it underscores that mothers were meant to have child care help.
