Testosterone usually controls your sex drive, having low testosterone can cause you to have less desire for sex which can cause you from keeping your erection (fire) up. With treatment you can keep your testosterone levels up, thus keeping your erections up. Low-T can kind of make a guy feel like he is experiencing erectile dysfunction.
Low-T, most times when it’s diagnosed, is short term, but on the other hand ED, most times when it’s diagnosed, is long term.
But to answer the question, can low testosterone cause erectile dysfunction (ED)? Well, the jury is still out on that one. There is no conclusive answer as to low testosterone being a primary cause of ED. It can be part of the cause, but more likely it is in cohorts with something else.
With all the different causes of erectile dysfunction, most times it is difficult to be certain if whether it’s a symptom of low testosterone or something else. A good clue is whether other symptoms of low testosterone are present, like, a reduced sex drive, anxiety, irritability, difficulty concentrating, or depression.
The best way to find out for sure is with the advice of a qualified doctor. It’s important to have your doctor size up the ED to find out if it may be the result of underlying cardiovascular disease, psychological causes like stress or performance anxiety, or potentially due to very low testosterone.
