Low testosterone, or low T, is a medical condition in which the body does not produce enough testosterone, a hormone that is important for male development and physical characteristics. Testosterone plays a key role in maintaining muscle mass, bone density, sex drive, and energy levels in men. Low testosterone levels can result in a range of symptoms, including fatigue, decreased sex drive, erectile dysfunction, depression, and decreased muscle mass. It is more common in older men, but can also affect younger men due to certain medical conditions or lifestyle factors.
Low testosterone can also have effects on the body, including increased risk of osteoporosis, cardiovascular disease, and type 2 diabetes. It's important to note that these symptoms can also be caused by other medical conditions or lifestyle factors, so it's important to consult with a qualified healthcare provider for an accurate diagnosis.
