Is Low Testosterone Genetic?

Low testosterone means a man does not have enough of the hormone that is very important for many body functions. Research shows that genetics can contribute to this condition. In some cases, men inherit specific genes or variations that affect how well their bodies make testosterone. For example, Klinefelter syndrome is a well-known genetic condition where a man has an extra X chromosome, which often leads to lower testosterone levels. Studies using large groups of people have found markers in the genes that seem to be connected with low testosterone. This means that if your family has a history of low testosterone or related conditions, you might be at a higher risk. However, it’s important to know that while genetics is a key factor, many other things like age, weight, and overall health also influence testosterone levels. If you’re worried about low testosterone, discussing your concerns with a doctor can help determine if genetic factors may be playing a role and what steps you can take next.
