Our Find a Provider tool makes it easy to search Cleveland Clinic’s trusted network. Together, you and your healthcare provider will weigh the risks and benefits of TRT to see if it could help. Testosterone replacement therapy may be an option for you. But there aren’t many studies on the long-term effects of TRT (for example, over decades). Your body will take some time to restart production of testosterone naturally. But it’s important to remember that TRT comes with potential risks and side effects. If you stop taking testosterone, your body will have to recover its ability to make testosterone again. In second pass, an additional 419 studies were excluded. The original guideline search strategy was updated and used to systematically search PubMed for new evidence published between the previous search end date and February 2022. An updated evidence search was subsequently performed in 2022. Controlled vocabulary supplemented with keywords was used to search for studies according to each defined question. For some people, such as those who have hypogonadism or are transitioning, these risks may be worth the benefits. Another meta-analysis by Calof et al.190 (2005) pooled data from 19 RCTs to determine the number of all-cause prostate events in men who were on exogenous testosterone treatment as compared to men who were on placebo. Since Huggins' work, subsequent research has failed to definitively link testosterone therapy to a progression of prostate cancer in the untreated patient or recurrence in the treated patient. The controversy surrounding prostate cancer and testosterone stems from the work of Dr. Charles Huggins who discovered that treating metastatic prostate cancer patients with ADT resulted in cancer remission,341 suggesting that the presence of testosterone would lead to an increased likelihood of prostate cancer development. The relationship between testosterone therapy and the development of prostate cancer has been debated. Overall, seven studies reported no benefits on QoL in men using testosterone therapy compared to placebo,199, 205, 212, 225, 226, 230, 303, 318 while five studies demonstrated improvements.203, 317, 319, 328, 329 The impact of testosterone therapy on QoL in men with testosterone deficiency is challenging to quantify due to variable study methodology and inherent limitations with standardized questionnaires. Testing intervals are the expert opinion of the Panel and are provided as a guide to aid clinicians in the follow-up of such patients. Patients who are on long-acting SQ pellets require two separate assessments of testosterone to determine the dose and frequency required. As with short-acting IM testosterone injections, the general recommendation is mid-cycle testing, after equilibration, and halfway between the first two 10-week injections. While no data exist on the optimal timing of the blood draw within a cycle, it has historically been recommended that blood draws be conducted mid-cycle. Given the mechanisms of action of anastrozole, clomiphene citrate, and hCG, patients using these medications should wait a longer period before follow-up blood work is performed. In the IM testosterone group, there were no new cases of gynecomastia, and one patient with pre-existing gynecomastia had gynecomastia resolution.181 An evaluation for a prolactinoma in such patients is imperative because these benign tumors can be effectively managed using medications, such as bromocriptine or carbergoline. However, the literature at this time fails to define the LH level below which such adjunctive testing is warranted. The validated instruments include ADAM, Quantitative ADAM, Aging Male Survey (AMS), MMAS, and the ANDROTEST.10, 166, 167 Specificities and sensitivities vary greatly amongst these tests making them ill-suited for screening or for use as a surrogate for testosterone laboratory testing. Due to the performance-enhancing properties (e.g., increased strength and power, shortened recovery time) of this class of drugs, use of any anabolic agent including testosterone and other anabolic steroids in NCAA athletics participation is banned. Because the regulation of nutritional/dietary supplements is limited, any nutritional/dietary supplement or other product that may unknowingly contain a banned ingredient is taken at the student-athlete’s own risk. A total of 10.1% contained components with data to demonstrating a negative effect on T. In addition, only the first and most frequently appearing 50 supplements were included in the study, acknowledging that other products and supplements may be available that were not studied here. Relatively low levels of zinc over-supplementation have been shown to interfere with the utilization of copper and iron and to adversely affect high-density lipoprotein cholesterol concentrations. The FDA does not issue RDA and upper tolerable limit data for herbal supplements. However, a 2016 article suggests there was little evidence for its effectiveness. Dehydroepiandrosterone (DHEA) is a hormone that occurs in the body, and people can purchase it as a testosterone supplement. However, studies examining its effects on humans are inconclusive and mainly of poor quality. Tuna is rich in vitamin D, which has been linked to longer life and testosterone production. Certain foods help boost your testosterone naturally such as egg yolks and tuna. Your body naturally makes a hormone called DHEA that it can convert to testosterone. This, in turn, can have a harmful impact on your testosterone. In addition, testosterone is essential for health and well-being, as well as the prevention of osteoporosis. McGill, J. Cleveland Clinic Journal of Medicine, November 2012. Within 1 to 2 years of TRT, your doctor will measure your bone density if you had osteoporosis when treatment began. The individual can then make a better decision about the potential benefits they would have and weigh them against the risks. People may wish to supplement their testosterone to counteract these natural effects of aging. A person can only purchase testosterone with a valid prescription from a healthcare professional. There are various ways a person can take testosterone, such as subdermally, by injecting the hormone, or orally. Anabolic steroids contain testosterone that is either natural or synthetic.
