Testosterone Levels by Age: Normal Levels for Males and Females

Normal Testosterone Levels and Symptoms of an Imbalance

Symptoms of low testosterone include fatigue, reduced libido, weight gain, and emotional changes. If you notice these symptoms, it is advisable to consult a healthcare provider. Leptin, a hormone found in fat cells, is thought to inhibit testosterone production, says. Excess fat cells can also increase estrogen levels, which lowers testosterone. Healthy levels are typically between 264 nanograms per deciliter (ng/dL) and 1,000 ng/dL, according to some doctors. Anything below 264 ng/dL is low, and high testosterone is above 1,000 ng/dL. It may be noted that the normal levels of testosterone in men tend to decrease naturally at a rate of 1 percent per year after they are 30 years old.

If you have questions or concerns about your health, please talk to your doctor. Testosterone replacement therapy can reduce the unwanted effects of low testosterone and give you your life back. It’s not unusual for men to experience these symptoms even at 400 ng/dL, 600 ng/dL, or higher—depending on their free testosterone, SHBG, thyroid function, and overall hormone balance.

Lower than normal testosterone levels can cause weaker or diminished orgasms, reduced sexual wants, and reduced muscle mass and bone density which may then lead to a decrease in overall strength. For males, testosterone therapy may help treat lower-than-normal testosterone levels. However, there’s inconsistent evidence on the benefits of testosterone therapy for aging-related declines in testosterone. Some evidence also shows testosterone therapy may increase your risk of cardiovascular issues. If lifestyle changes don’t relieve low testosterone symptoms, testosterone replacement therapy may be an option under the care of a healthcare provider. Potential benefits include increases in energy, libido, sexual function, muscle mass and bone density. Testosterone levels in men typically decline by about 1% per year after age 30.

A doctor could also recommend hormonal contraception and fertility treatment. People of all sexes may also experience hair growth on the face and body, greasy skin, and a range of other symptoms. Generally, males have much higher levels of testosterone in their bodies than females. Upon receiving the results of your blood test, your T levels may be close or under the bottom of the range. If your doctor refuses treatment, a gentle reminder of what “optimal health” entails may be in order.

A healthy testosterone level will vary between people based on factors such as age and sex. If people are not experiencing problems with puberty, growth, development, fertility issues, or metabolic disorders, they will likely have a suitable level of testosterone. A retrospective cohort study from the U.S. showed that testosterone replacement in men with hypogonadism significantly increased the risk of urolithiasis [25]. In another retrospective case‒control study from Taiwan, androgen deprivation in prostate cancer patients reduced the subsequent development of kidney stones [26]. These two retrospective studies suggest that testosterone might induce urinary stones.

Consulting with our specialists can guide you to the best treatment options. Such findings underscore the importance of a tailored approach to health assessment, where both the numbers and individual experiences are steroids testosterone boosters considered. As research in this field progresses, our understanding of testosterone’s impact on men’s health will continue to evolve, potentially leading to more personalized healthcare strategies. These results establish a conservative guideline for what’s considered normal, focusing strictly on the middle values. However, as more data is gathered and analyzed, these ranges may be adjusted to better reflect the natural variations in testosterone as men age. Doctors might also recommend lifestyle adjustments, such as exercising more, losing weight, getting more sleep, reducing stress, and eating a healthy diet, Gittens says.

Additionally, high protein intake, which in turn increases serum albumin [23], is related to the development of nephrolithiasis [24]. Hence, the serum albumin level was adjusted as a parameter of high protein intake to elucidate the association between testosterone and nephrolithiasis. In 2025, clinics like AlphaMan, a men’s health center specializing in hormone optimization, are rethinking how testosterone therapy fits into modern masculinity.

Assess total and free testosterone, SHBG and albumin levels to evaluate male hormone health. Unfortunately, many medical professionals haven’t had the necessary training to understand hormones and what it means to have optimal levels. While they may be aware of the need for hormone replacement, they focus on baseline test numbers that don’t even come close to telling the whole story.
