Men were excluded if they were started on TRT prior to angiography or prior to obtaining serum T levels, as ‘time 0’ was defined as time of angiography, not time of commencement of T therapy. The authors reported that only two trials provided a comprehensive list of cardiovascular-related events while eight trials did provide a summary table of cardiovascular-related events, yet cardiovascular events reported in the remaining 17 trials were inferred but not explicitly stated, leading to some modest speculation. Second, it is difficult to make firm conclusions from these figures as there were no consistent methods of reporting or quantifying adverse cardiovascular events. First, it is reasonable to assume pharmaceutical industry funded studies may be more robustly funded overall and should in theory report adverse events more diligently. 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. Older observational studies suggested that long term testosterone use could increase their risk of cardiovascular disease. The Cleveland Clinic adds that TRT is also unsafe if you have certain existing health conditions like prostate cancer, breast cancer or heart failure. Before testosterone therapy is recommended, a doctor may test levels multiple times to determine the best treatment option. But the researchers found no consistent evidence showing an increase in cardiovascular disease risk in trans men taking testosterone. According to the research, testosterone therapy does appear to have an effect on blood pressure and lipid levels in transgender men. 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. General fatigue and malaise has so many other causes, and when most men get a blood test, the result is a normal testosterone level. "One of the problems is that there are a lot of people, guys out there who are taking testosterone because they want to feel younger — they want the muscle, they want to get jacked up. But there are problems with it." While the treatment may have an impact on muscle strength and how people feel, LaPook said there is limited evidence on the extent of potential benefits and potential dangers. "This is something where you don't want to be going online and just getting it and taking it at home and not following the levels. You need somebody who's professional." "For adult females, testosterone enhances libido. However, the majority of testosterone produced in the ovaries is converted to the primary female sex hormone, estradiol," the clinic's website reads. Testosterone is a hormone produced primarily in the testicles that helps develop or maintain bone, muscle and fat, as well as facial and body hair, red blood cells, sex drive and sperm production. Prescriptions for the treatment rose from 7.3 million in 2019 to more than 11 million last year.
