As men age, some men develop androgen deficiency, which is manifested by changes such as decreased muscle mass and muscle strength, decreased libido or erectile dysfunction, skin laxity and osteoporosis. For middle-aged men with low androgen levels due to certain reasons, androgen supplementation is theoretically reasonable. However, appropriate hormone level tests should be done to further confirm. The ideal method of androgen supplementation is to take oral testosterone drugs. Blood testosterone levels should be tested regularly while taking the medication. It is important to note that testosterone supplementation may aggravate the symptoms of latent prostate disease such as prostate enlargement and prostate cancer. Therefore, it should be used with caution in patients with prostate conditions. It should also be used under the close supervision of a physician if you have heart disease, kidney disease, or high blood pressure.
