Androgen Replacement Therapy (ART) is a medical treatment designed to restore normal levels of androgens, primarily testosterone, in individuals with low hormone levels. This therapy is commonly used for men experiencing symptoms of hypogonadism, which can include fatigue, reduced libido, and muscle loss. ART can be administered through various methods, including injections, patches, gels, or pellets. The goal of ART is to alleviate symptoms and improve quality of life. Regular monitoring by a healthcare provider is essential to ensure the therapy is effective and to manage any potential side effects, such as changes in mood or increased risk of certain health conditions.
