Testosterone therapy is a medical treatment that involves the administration of testosterone to address low levels of this hormone in the body. It's primarily used to increase testosterone levels in individuals with conditions such as hypogonadism. Testosterone therapy can be delivered through various methods including injections, patches, gels, or pellets. The goal of this therapy is to alleviate symptoms associated with low testosterone such as fatigue, low libido, and muscle loss. However, it's crucial to consult with a healthcare professional before starting testosterone therapy to determine its suitability and potential risks, as it may not be suitable for everyone.
