Testosterone is the most important male hormone and is produced by the testicles. It is essential in maintaining healthy sexual function, energy levels, mood, strength and levels of muscle and fat in the body. Its levels decline naturally as a man gets older. Testosterone deficiency in men is a common but often-missed diagnosis. This blood test is to measure testosterone levels in the blood.

- Loss of libido or sex drive
- Difficulty in getting an erect penis (erectile dysfunction)
- Inability of your partner to get pregnant (infertility)
