Testosterone is the androgenic hormone mostly responsible for the growth and development of male sex and reproductive organs, which include the penis, testicles, scrotum, prostate, and seminal vesicles. Testosterone production declines naturally with age, but men with diabetes are 50 percent more likely to have testosterone deficiency.
Causes include damage to the hypothalamus, pituitary gland, or testicles that inhibits hormone secretion and testosterone production. Insufficient testosterone production can lead to abnormalities in muscle and bone development, underdeveloped genitalia, and diminished virility.
Symptoms of testosterone deficiency don't start overnight. They begin gradually and grow in frequency and strength as you age. Here are a few signs:
- A low sex drive and weak erections.
- Chronic fatigue and depression.
- Forgetfulness. Low level of testosterone can result in memory loss.
- A loss in bone density (osteoporosis).
- Loss of strength and muscle mass.
- Fat build up, especially around the stomach and waist area.
Other subtle symptoms of low levels of testosterone include timidity, feeling of weakness and passive attitude.
