Sexual Problems in Men
So far you've indicated that you don't take medications, and don't drink alcohol or use drugs.
Since hormones, especially testosterone, play an important role in sex drive, certain hormone abnormalities can cause your sex drive to go down. There are many different symptoms of hormone problems, but common symptoms that might be linked to sexual problems include
sudden weight loss or gain
a change in your voice
a change in your pattern of hair growth
fragile bones (osteoporosis)
loss of muscle tone or bulk
loss of peripheral vision ("tunnel vision").
Have you noticed any of these symptoms that might suggest a hormonal problem?
