Testosterone Replacement Therapy (TRT) is a medical treatment designed to increase levels of testosterone, a hormone that plays a key role in male health. It is often prescribed for men who have low testosterone levels, which can lead to symptoms such as fatigue, reduced libido, and mood changes. TRT can be administered through injections, patches, gels, or pellets. The therapy aims to restore testosterone to normal levels, improving overall well-being and quality of life. While TRT can be beneficial, it is important for patients to discuss potential risks and side effects with their healthcare provider to ensure safe and effective treatment.
