Are you developing more fats at your waistline and feeling less macho as your sexual drive has decreased? If that is the case then you may be losing your sexual hormone.
A new research claims estrogen-a female hormone- may be responsible for less sex drive and more fat in aging men.
Estrogen – the female hormone – is needed by men, too, says scientists adding the dearth of these hormones may cause certain “male menopause” symptoms.
All men have some estrogen, just as all women have some testosterone. A small portion of the testosterone in a man’s body is routinely converted to estrogen via a hormone called aromatase, says Dr. Joel Finkelstein, who is also an associate professor at Harvard Medical School.
“Levels of both estrogen and testosterone decline with age, says researchers.
Until now, there was no way to tell which hormone was responsible for complaints of diminished libido, strength and energy, but the study has finally put an end to various speculations.
Millions of men have been prescribed testosterone gel, patches or shots for these problems, but it’s not known how much they need or whether this hormone replacement therapy is good, bad or neutral, Finkelstein said. Doctors don’t usually prescribe estrogen to men; the way to remedy low estrogen is to give them testosterone and let the body convert it.
The study didn’t test hormones as therapy, but explored which ones had which effects.
The scientists carried study on 400 healthy male volunteers, between age group 20 and 50. They were given monthly shots of a drug to temporarily reduce their testosterone production to pre-puberty levels. They were then given various doses of testosterone gel or a dummy gel to use. Half also were given another drug to prevent testosterone’s conversion into estrogen.
After 16 weeks, the researchers then compared the effects of different levels of each hormone on things like strength and body composition.
The 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.
