While low testosterone is often blamed for lowered sex drive and potentially dangerous increased fat accumulation in men, recently doctors discovered that a lack of estrogen is to blame.
While low testosterone is often blamed for lowered sex drive and potentially dangerous increased fat accumulation in men, recently doctors discovered that a lack of estrogen is also to blame.
It has been known for awhile that a low level of the female hormone leads to weakened bones in men, just as it does in women.
Now researchers from Massachusetts General Hospital have found low estrogen levels to be the key factor behind the decline in men’s sexual health, and feel this could lead to big changes in the practice of prescribing hormones to men.
What the researchers set out to better understand was how many testosterone problems were linked to estrogen, as the male body naturally converts some of the former to the latter.
To test it out, they adjusted the hormonal balances of 300 men between the ages of 20 and 50.
All participants had their natural testosterone production diminished. Half received a placebo testosterone replacement and the other half got the real thing, but in varying four degrees of dosage intensity.
The men receiving the real hormone were subdivided into two smaller groups with some receiving a medication to block the conversion of testosterone to estrogen, and the others not.
Men with low estrogen levels were most afflicted, and the results shed light on where the previously testosterone-attributed problems, like fat accumulation and sexual dysfunction, were really coming from.
