As men get older, their testosterone levels naturally decrease. This can lead to a range of side effects, including decreased energy levels, reduced libido, and difficulty sleeping. Many aging men are turning to Testosterone Replacement Therapy (TRT) to combat these effects.

According to the American Urological Association (AUA), testosterone therapy can be considered if serum levels of testosterone are under 300 ng/dl and clinical symptoms are present. These symptoms include decreased sex drive, erectile dysfunction, depression, and fatigue.
Testosterone replacement therapy is available in several forms, including topical gels, patches, pellets implanted under the skin, and injections. There are also lifestyle factors that can come into play that may affect testosterone levels. For example, sleep deprivation and obesity can contribute to lower testosterone levels.
With functional medicine, men can optimize their testosterone levels naturally through lifestyle changes such as improving sleep quality, incorporating regular exercise, reducing stress levels, and managing underlying health conditions. In addition, specific vitamins, minerals, and herbs have been found to support healthy hormone production.
So, what is the optimal range for healthy aging men’s circulating testosterone target levels? And how can you know if TRT is right for you? Read on to learn a bit more about testosterone levels and aging.
What is Testosterone?
Testosterone is the primary male sex hormone responsible for a range of physical and psychological functions. It’s produced in the testicles and helps maintain muscle mass, bone density, and sex drive.
What Are The Symptoms Of Low Testosterone Levels?
Low testosterone levels can lead to a variety of symptoms, such as:
Decreased energy and muscle strength
Loss of libido
Erectile dysfunction
Depression
Difficulty sleeping.
When these symptoms are present, they can lead to a decrease in self-esteem, an inability to concentrate, and can lead to poor productivity. Men who wish to improve their overall health and well-being should consider having their testosterone levels checked.
Understanding How Low Testosterone Impacts Healthy Aging
As we age, our testosterone levels naturally decrease. Low serum total testosterone concentrations may indicate an underlying physiological imbalance that functional medicine practitioners assess when creating personalized treatment plans for their patients’ diagnoses.
Researchers analyzed survey data from the National Health and Nutrition Examination Surveys (NHANES) to determine optimal ranges for healthy aging men’s circulating testosterone target levels. Their studies found that an optimal range for healthy aging males was between 300-1,000 ng/d – which began to drop after age 50.
In addition to TRT, there are various other ways to increase testosterone levels naturally. Lifestyle interventions such as high-intensity interval training and reducing alcohol intake can help raise free testosterone levels. Certain foods and herbs may also have positive effects on.
In addition to TRT, there are also lifestyle interventions that can help increase free testosterone levels naturally. High-intensity interval training and reduced alcohol intake have boosted testosterone levels in men. Certain foods and herbs may also positively affect increasing hormone concentrations, such as garlic, ginseng, and maca root. Combining a healthy diet with exercise is key to maintaining healthy testosterone levels.
Potential Side Effects of TRT
It’s important to note that testosterone therapy has been linked to side effects such as reduced fertility, fluid retention, and obstructive sleep apnea; there is conflicting evidence regarding cardiovascular risks associated with supplementation. Before beginning TRT, it’s best to consult with a physician to determine if it’s the right option for you and discuss other potential health risks.
However, TRT can be an effective option for many men when implemented as part of a functional medicine approach for low serum total testosterone and healthy aging. Working with a functional medicine practitioner to create a personalized treatment plan is the best way to ensure you get the safest and most effective care possible.
