If you have low T, your levels of the male sex hormone, testosterone, drop below normal. When that happens it may affect your sex life. Your sex drive could go down. And you might develop erectile dysfunction (ED).
Men with ED have trouble getting or maintaining an erection suitable for sex.
ED Has Many Causes
It's important to remember that low T isn't the only cause of ED.
Psychological problems such as depression, anxiety, and relationship issues are also possible causes of ED. So are multiple sclerosis, spinal cord injuries, chronic back pain, and other neurological conditions.
The Link Between Low T and ED
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.
Testosterone Replacement Therapy and ED
If your testosterone level measures in the normal range, raising it through testosterone replacement therapy (TRT) probably won't help your ED. Instead, you'll have to look for and address other causes.
While many men on TRT do report improvements in their erections, they often need added help from ED drugs known as PDE-5 inhibitors, such as:
Some research suggests that erection improvements that result from TRT may not last over the long term.
Treating low testosterone can improve a man's sex life by restoring his libido and brightening his mood, thereby renewing his interest in sex.
