Does every male with low sex drive or decrease in libido need testosterone therapy? Testosterone is produced in both men and women. It does help maintain muscle strength and mass as well as bone density and even cardiac function. Men with lower levels of testosterone are at a risk for cardiac events.
A small study of 470 men who were older than 65 years old who had a low libido were studied. Each of these men had levels less than 275 ng/dL These men were assigned to take either testosterone gel or placebo for one year. The increase in libido was measured by certain questions
It was found that testosterone supplementation improved 10 of the 12 questions . After reading the study I found one interesting point —The increase in testosterone improved sexual activity and desire but NOT erectile dysfunction
