Does Low Testosterone Cause Erectile Dysfunction (ED)?

Testosterone is a hormone that is important for a man's sexual health. When testosterone levels are too low—a condition called hypogonadism—it can lead to problems such as a low sex drive and sometimes trouble with erections. Research shows that for some men who have low testosterone, taking testosterone replacement therapy can help improve their ability to get and keep an erection. However, erectile dysfunction (ED) is usually not caused by low testosterone alone. Other issues, like problems with blood flow, nerve damage, stress, or other health conditions such as diabetes or heart disease, can also play a big role in ED. In simple terms, low testosterone might be one piece of the puzzle when it comes to ED. If you're concerned about ED or low testosterone, it’s important to speak with a doctor. They can check your hormone levels and look at other possible reasons for your symptoms. With the right information, your doctor can help decide the best treatment plan for you.
