We know that hormone levels become unbalanced with age, but new research shows that lack of estrogen may actually be responsible for a low libido and increase in weight gain as men age. Although estrogen is known as a female hormone, this chemical also plays a role in men's health.

Dr. Joel Finkelstein of Massachusetts General Hospital led the study which is published in the New England Journal of Medicine. The research involved 400 healthy male volunteers, ranging in age from 20 to 50. These participants were given monthly shots of a drug that temporarily reduced their testosterone levels to that of pre-puberty. Half of the men were also given another drug which blocks the conversion of testosterone into estrogen.

"After 16 weeks, researchers saw that muscle size and strength depended on testosterone, body-fat mass depended on estrogen, and both hormones were needed to maintain normal sex drive and performance," Care2.com reported.

The results mimic similar studies performed on animals. It is a known fact that men's bodies convert some of the testosterone into estrogen. Since doctors don't typically prescribe estrogen to men, the way to fix a low estrogen level is to give males testosterone and let the body naturally convert it.

Ultimately, as you age, it is important to ensure that your body has the correct amount of hormones, which can aid in both your physical and mental health.
