What are Normal Testosterone Levels in Men by Age? Rebalance Health

That should give any knowledgeable doctor a red flag that T levels aren’t on par. Testosterone levels begin to decline when you reach your mid-thirties, and drop further as you age. Changes in mood, energy levels, or cognition might signal low testosterone levels. “Many studies [that look at testosterone levels] take an amount of people across these ages and test them for their T levels,” says McDevitt. The researchers don’t factor in pre-existing conditions or peoples’ lifestyles, which can skew the results, she notes. Additionally, testosterone influences mood, energy levels, and overall physical and mental health.

You want to get your testosterone therapy from a facility with a proven track record in understanding the nuances of prescribing hormone replacement for your unique needs and lifestyle. “You don’t need to wait until something feels ‘off’ to check in with a doctor,” says Houman. Instead, you can talk to a healthcare provider if you’re just curious about your hormone health, he says. Foods that are high in polyunsaturated fats (PUFAs) like flaxseed, some vegetable oils, and nuts may also decrease testosterone levels. If you drink herbal teas or other flavored drinks, you might have seen licorice root as an ingredient on the label. Licorice root may significantly decrease testosterone levels in as little as one week if taken in large quantities. Processed foods high in trans fats may also decrease testosterone and may even reduce sperm count.

If your levels come back low and you have symptoms of low testosterone, you may be a candidate for testosterone therapy. It can also help prevent obesity which is detrimental to maintenance of normal testosterone shots cost levels. Body fat causes reduction of testosterone and increases estrogen levels. In other words, men with higher testosterone levels at the start of the study had a lower rate of decrease—or no decrease at all—as they aged. This highlights the importance of maintaining healthy testosterone levels at any age, especially before old age. In general, a man in his twenties without chronic conditions will have higher testosterone levels than a man in his fifties with medical issues.

However, these results are limited because the data are derived from military service members and individuals with pathological conditions such as prostate cancer. Therefore, these retrospective results might lack some degree of generalizability beyond former service members and patients with prostate cancer. The primary aim of our study was to elucidate the relationship between serum testosterone levels and nephrolithiasis. Testosterone has been postulated to be a risk factor for urinary stones since the prevalence of stones is two to three times greater in men than in women [4, 5]. Recent laboratory data from rats also revealed that finasteride interferes with the crystal formation of calcium oxalate, the most common stone component [7]. While you’re with them, a doctor may recommend blood tests to assess hormone levels, says Houman. From there, they might provide guidance on healthy lifestyle changes, such as the tips above.

Generally, total testosterone levels below 300 ng/dL (nanograms per deciliter) may indicate low T, but it’s nuanced. Free testosterone (the active form) also matters, as does the patient’s overall health picture. The following tables outline female and male average testosterone levels by age in chart format. A recent study found that age-related testosterone deficiency was the most important factor of bone loss in elderly men.

In particular, resistance training, high-intensity interval training (HIIT), and walking have been shown to positively affect testosterone levels. Too much testosterone can also cause hypertension, or high blood pressure (8). It’ll cause the red blood cells to overproduce which can, in turn, create a clot in your blood vessels. You want smooth blood flow, so an increase in red blood cells could easily cause stagnation. T levels in men can vary widely, though they generally decline in men after the age of 35 says McDevitt.

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.

According to the American Urological Association (AUA), healthy male testosterone levels range between 450 and 600 ng/dL, and low testosterone is below 300 ng/dL. The prevalence of nephrolithiasis is increasing worldwide [1, 2], and the recurrence rate is close to 50% [3]. Additionally, urinary stones have a negative impact on quality of life and impose a significant economic burden on patients and health care systems. The following charts illustrate the normal testosterone level ranges per age for men and women. One that the older you get, the lower your testosterone levels can drop.
