Normal & Average Testosterone Levels By Age Hormone Replacement Therapy

Research finds that normal testosterone levels in men are affected by factors outside of your control such as ethnicity and chronic diseases. Increased body fat may have a negative impact on hormone signaling between the brain and the testes, leading to decreased production of testosterone. Lower testosterone levels in larger men may also be related to the increased risk of other chronic conditions that can impact your hormones.

Some research suggests a potential link between higher exposure to endocrine-disrupting chemicals (EDCs) and lower testosterone levels, says Houman. This is likely because they can disrupt both endocrine function and healthy metabolism. A 2023 study in Environmental Research reports a link between EDCs and a decrease in serum testosterone. And other research has shown that these chemicals, as their name suggests, can negatively impact the endocrine (hormone) center, leading to disruptions in hormone balance. Meanwhile, a 2017 study in Current Obesity Reports found that endocrine-disrupting chemicals can promote the accumulation of adipose (fat) tissue and cause weight gain. In both sexes, testosterone contributes to overall health and well-being.

A careful evaluation of the benefits and risks, personalized to your health status and needs, is the best approach to managing low testosterone levels in men.

As males age, their testosterone levels may decline by up to 2% annually after age 30 years.
