What is the link between testosterone and erectile dysfunction?

Low testosterone is the primary cause of erectile dysfunction in only a small minority of cases, around 5%. In men with low testosterone levels, treatment can lead to modest improvements in erectile function, but it provides little or no benefit for those with normal levels. The two conditions often occur together due to shared risk factors like ageing, obesity, and cardiovascular disease, though low testosterone does not directly cause most erectile dysfunction.

Key points:

• Low testosterone directly causes erectile dysfunction in about 5% of cases.
• Testosterone treatment improves erectile function modestly in men with low levels.
• No meaningful benefit from testosterone treatment occurs in men with normal levels.
• Physical conditions like cardiovascular disease and diabetes link low testosterone and erectile dysfunction.
