Depending on your symptoms, your doctor may also perform a physical examination. If you’re male, your doctor may perform a physical if they notice:
- a loss of facial hair
- a loss of height
- signs of gynecomastia, an abnormal increase in breast tissue size
- abnormal weight gain
If you’re female, your doctor may perform a physical if they notice:
- abnormal facial acne
- abnormal hair growth on your lips or chin (hirsutism)
- abnormal hair thinning or balding on the head
Testosterone home testing kits are widely available from several companies, such as Progene. They use your saliva to test your hormone levels. After taking the test, you’ll send your sample to a laboratory for testing.
Several studies, including one that sampled nearly 1,500 men between 20 and 90 years old, have confirmed that saliva offers a relatively accurate measurement of testosterone levels. This is especially true when diagnosing male hypogonadism.
