Why Is Low Testosterone Significant?
Testosterone is the male sex hormone that is produced in the testicles. Testosterone is responsible for making sperm and developing masculine traits (such as a deeper voice, body and facial hair, and greater muscle mass). Symptoms of low testosterone include erectile dysfunction, low sex drive, fatigue, reduced muscle mass, irritability, increased fat mass, and depression.
The following are some causes of testosterone deficiency:
- Chemotherapy
- Radiation
- Damage to testicles
- Infection
- Autoimmune disease
