What conditions testosterone is used for
Testosterone is used to treat low testosterone levels, which can cause symptoms like fatigue, low libido, which is sexual desire, and mood changes. It helps improve energy, sexual function, and mood. It's often used for conditions like hypogonadism, which is when the body doesn't produce enough testosterone.
How testosterone works in the body
Testosterone works by binding to androgen receptors, which are proteins that respond to male hormones. This helps regulate male characteristics like muscle mass and facial hair. It also maintains bone density and red blood cell production, improving symptoms like low libido and fatigue.

Testosterone is usually taken as an injection, patch, gel, or tablet. Injections are given every 1 to 4 weeks. Patches and gels are applied daily, usually in the morning. Tablets are taken as directed by your doctor. Always follow your doctor's instructions for the best results.

Testosterone can increase the risk of heart problems, such as heart attack or stroke, especially in older men. It may also cause blood clots and worsen prostate cancer. It's contraindicated in people with prostate or breast cancer and those with severe heart, liver, or kidney disease.
