What is the link between low testosterone and erectile dysfunction (ED)?

ANSWER

Erections depend on testosterone, but the relationship between the two is complex and not fully understood. Some men have healthy erections despite testosterone levels well below the normal range.

What is clear is that low testosterone levels are linked to a number of the same chronic conditions that play a role in erectile dysfunction, such as type 2 diabetes, obesity, and heart disease.
