You no longer need to visit your doctor’s office to get your hands on a testosterone prescription. The barrage of ads and easy access to doctors who prescribe testosterone has convinced many men that they need to take the hormone. Even if a supplement boosts testosterone a bit, that doesn't mean it's addressed any of the issues caused by low testosterone. But a bad test was a problem with a 2019 ashwagandha study. "There are many bad tests out there," says Anawalt, who adds that there is a national effort to standardize testosterone tests. What’s more, testosterone is notoriously tricky to measure. The Saturation Model postulates that the androgen receptors on the prostate are saturated at physiologic and even subphysiologic levels of T, such that there is minimal response of the prostatic tissue to TRT. Only seven men throughout the study were found to have PSA levels above 4.0 ng/ml, six of whom were treated for suspected prostatitis with a resultant interval decrease in PSA. One hundred and sixty-one men completed the 1-year study and 115 entered into a 5-year study extension; 51 men completed the sixth year of the study and reported a statistically significant increase from a mean baseline of 0.50 ng/ml to a mean level of 0.80 ng/ml (95% CI 0.19–0.41). To date, there are no prospective studies that have evaluated the risk of VTE in men receiving exogenous T supplementation. Similarly, a prospective, population-based study of 1350 men aged 50–84 years yielded only 4.5 VTE events per 1000 person-years over 10.4 years of follow up with an insignificant HR of 1.06 (95% CI 0.83–1.35) Svartberg et al. 2009. Additionally, the authors admit that they were unable to explore whether or not the increase in CVD mortality was directly related to serum T levels or baseline TD. A limitation of this study centers on utilization of a healthcare database that did not include information on either serologic or diagnostic criteria for men who received TRT. Despite insufficient scientific data to support claims, manufacturers have suggested their products increase muscle mass, strength and sex drive in men. Methyltestosterone, which is the generic name of Android and other caplets or tablets, is an artificial form of testosterone alone. They were used to treat delayed puberty in men and boys and breast cancer in women. Combined estrogen-methyltestosterone capsules have been discontinued. The active ingredient, testosterone cypionate, is a powder mixed with other ingredients to make a solution. First approved in 1979, Depo-testosterone is one of the older drugs of its kind on the market. This can potentially lead to serious health reactions for the other person. In a 2022 research anaylsis, researchers investigated cardiovascular events and deaths in men with hypogonadism undergoing testosterone therapy. Males who have low testosterone levels can choose to have testosterone replacement therapy to bring their levels back to optimal levels. The effect on your blood pressure may depend on your own health, whether you have any heart disease or high blood pressure, and how much testosterone you take. Men with prostate cancer or elevated prostate-specific antigen (PSA) should probably avoid testosterone treatment. If you have low testosterone levels but no symptoms, low testosterone treatment isn't recommended. In summary, testosterone therapy appears generally safe from an overall cardiovascular standpoint but may come with risks that must be weighed in balance with its potential benefits on an individual patient whose hypogonadism may be affecting their overall quality of life. As of January 2014, the FDA stated they are investigating the potential link but have not concluded ‘FDA-approved testosterone treatment increases the risk of stroke, heart attack, or death’. Testosterone can stimulate prostate cancer to grow. This condition, benign prostatic hypertrophy, can be made worse by testosterone therapy. If you have symptoms of low testosterone and tests show you have an abnormally low testosterone level (below 300 nanograms per deciliter), your doctor may suggest treatment. Talking with your doctor is the only way to know if testosterone therapy is right for you. Testosterone replacement therapy can have side effects, and the long-term risks aren't known. Many men with low testosterone report improved energy levels, sex drive, and mood after testosterone treatment. If you do want to discontinue taking testosterone, don't stop cold turkey. The researchers found that for 92 patients (61%), the effects of TRT did not continue, but they did for the other 59 patients (39%). They will also do a physical exam and ask whether you have the symptoms of low T before prescribing anything. You need a prescription from your doctor to access testosterone. Although there are many supplements claiming to boost testosterone, these over-the-counter products do not contain testosterone and lack any peer-reviewed evidence of effectiveness. Some effects of TRT can be felt within weeks, while others build over the course of months. More than 2 million Americans took testosterone products, including older men using them to improve libido. The rates increase for men in their 70s (28%) and 80s (49%). Hypogonadism is when the body does not produce enough testosterone, and it occurs in 19% of men in their 60s. Lack of this key sex hormone can also cause health issues, including osteoporosis, loss of muscle mass and strength (sarcopenia) and psychological symptoms. The FDA later warned men about the dangerous side effects of these products, including cardiac events. Aside from frequent monitoring of congestive symptoms and peripheral edema in this select population, TRT appears to be safe for patients with chronic kidney disease without dose adjustment. For men who clearly have testosterone deficiency, there is no apparent increased risk of heart attack or stroke or greater chance of developing a new prostate cancer from testosterone replacement therapy. Decades of research have shown that low testosterone levels are linked with an increased risk of cardiovascular disease, including heart attack and stroke. And whether taking additional testosterone when you already have normal levels increases your risk of heart disease, prostate cancer, or anything else is unknown. The possibility of an increased prostate cancer risk steered some patients away from testosterone replacement therapy in the early 2000s. For most cisgender and transmasculine men undergoing testosterone therapy, there doesn’t appear to be any increased risk of cardiovascular events. "There’s no signal that testosterone therapy increases the risk of prostate cancer," says Anawalt. There is conflicting research regarding whether testosterone replacement therapy leads to increased risks of cardiovascular events.
