Testosterone replacement therapy (TRT) is typically prescribed to relieve symptoms of hormonal imbalances in men, such as low testosterone levels. Here are some common signs that a man may need TRT: Low sex drive: Low testosterone levels can cause a decreased sex drive. Erectile dysfunction: Low testosterone levels can cause erectile dysfunction, which is the inability to get or maintain an erection. Fatigue: Low testosterone levels can cause fatigue and a lack of energy. Decreased muscle mass: Low testosterone levels can cause a decrease in muscle mass and strength. Increased body fat: Low testosterone levels can cause an increase in body fat, especially around the waist. It’s important to note that these symptoms can have many causes and may not necessarily be due to low testosterone levels. The decision to start TRT should be made only after a thorough discussion with a healthcare provider. The provider will consider a man’s medical history, current health status, and other factors when deciding if TRT is right for them.
