Andropause or androgen deficiency, is a condition that is associated with the decrease in the male hormone testosterone. It has also been referred to as "male menopause". Testosterone is the hormone that is responsible for the typical changes involved in male puberty, such as:
- Growth of your muscle mass - Growth of your body hair
- Lowering of your voice
- Changes in your sexual functioning
As men get older, the level of testosterone in the body and production of sperm gradually becomes lower, and they experience physical and psychological symptoms as a result of these low levels.
