The ratio of estradiol to androgens is the key factor in the development of gynecomastia rather than absolute increases in androgens themselves. Exogenous testosterone is known to cause an imbalance in the hypothalamic-pituitary axis. Case reports regarding testosterone supplementation leading to changes in hair patterns have been documented; however no randomized, placebo-controlled trials exist. While polycythemia may be an adverse side-effect, this is a potential benefit in patients with chronic renal failure and anemia. In patients with end-stage renal disease (ESRD) on dialysis, fluid shifts are less of a concern in patients on TRT since the fluid retention can be handled with dialysis. It has also been shown that TRT may improve hepatic function in patients with end-stage liver disease.
More research is needed, as other studies, such as one from 2023, yield conflicting results. Vitamin D is a micronutrient that plays a key role in many aspects of health. Stress and high cortisol can also increase food intake, weight gain, and the storage of harmful body fat around your organs. Sudden elevations in cortisol can quickly reduce testosterone. Testosterone is a steroid hormone that the body mainly produces in the testicles and ovaries. WebMD does not provide medical advice, diagnosis or treatment.
It can also be attributed to prior chemotherapy or prior radiation to the pelvic area. Though not common, low testosterone can be attributed in some people to a serious brain condition, such as a mass, so your doctor will want to rule that out. "Hormone production follows what’s called a diurnal rhythm, where your levels are lowest around midnight and they peak in the early morning," Dr. Pantalone says. Attempting to treat low testosterone without the help of a medical professional means you’re not addressing the underlying cause, which can be harmful. The market is booming with "natural" testosterone boosters, but Dr. Pantalone warns against buying into them.
One peer-reviewed study found that average T levels in men today are substantially lower than in the 1980s, even after accounting for aging and other health factors. "It’s about bringing your hormones back into a healthy, balanced range—so you can feel like yourself again." A 2020 meta-analysis found that TRT significantly improved depressive symptoms in men with low testosterone.
We also discuss how to adjust the dose of testosterone replacement depending on the method used for testosterone replacement, goals of testosterone replacement, and patient preferences. This chapter focuses on the different formulations and routes of administration of testosterone used to achieve physiological testosterone concentration and alleviate symptoms of testosterone insufficiency.

Here is how to take a cautious approach to testosterone therapy. Although this new information is somewhat reassuring, men and their doctors should still weigh these issues before committing to long term testosterone therapy. If a man's testosterone is below the normal range, it's best to repeat it once more to be sure before starting testosterone therapy - often staying on it indefinitely. Just being tired isn't enough to seek testosterone replacement therapy. Data on the safety of TRT specific to our aging population is not currently available; however TRT has been linked to prostate cancer, BPH, polycythemia and OSA. Until date, no longitudinal studies examine the impact of TRT on the cardiovascular system, however some studies suggest that TRT may serve as an adjunct rehabilitative therapy in patients with congestive heart failure (CHF).50,51,52
As with the other self-administered medications, non-compliance and patients self-adjusting the dose are important factors that affect treatment and require patient education. Once hypogonadism is diagnosed and TRT is decided as the treatment option, the different options for TRT must be discussed. Although these may be non-specific findings, recognizing them in the context of low testosterone suggests clinically significant hypogonadism (7).
One downside is that these pills are expensive and may not be covered by insurance, unless you've tried other methods of treatment and had no success or bad side effects. Be careful about letting children or female loved ones touch the treated area or touch unwashed clothes that were in contact with the gel, as testosterone may get transferred to them. Most testosterone is attached to proteins; the proteins control the amount of active testosterone in your body and prevent your tissues from using the hormone right away. The symptoms of low testosterone are sometimes obvious, but they also can be subtle. Women who've taken testosterone usually report an increase in sexual desire. Women and people assigned female at birth do produce testosterone as well as estrogen, though the amounts of testosterone are much smaller than those produced by men.
But there aren’t many studies on the long-term effects of TRT (for example, over decades). If you stop taking testosterone, your levels will return to baseline. This is because if your symptoms don’t improve, your testosterone level may not be the cause of your symptom. But it’s important to remember that TRT comes with potential risks and side effects.
