About You

There’s very little risk to getting a testosterone blood test. Low levels may indicate a delay in sexual development. High levels may point to precocious (early) puberty.
We source research from peer-reviewed medical journals, top government agencies, leading academic institutions, and respected advocacy groups. The Edge upholds the highest standards of health journalism. Focus on eating a high-protein diet, and consider adding these 14 testosterone-boosting foods to your grocery list. Research shows that men who exercise regularly have higher testosterone than those who don’t (10). Be sure to speak with your doctor or clinician on which method is best for you and your health needs. However, when you’re undergoing TRT, some people test to determine the peak amount of testosterone, and some people try to grab the trough, says McDevitt. Your testosterone is higher in the morning, so that’s the best time to test.
It is not currently possible to establish a universal reference range for premenopausal women — but that's not an excuse for not treating. Most practitioners don't even consider testosterone in women, and there's a significant research gap around androgens in postmenopausal women. Clinical trial data typically uses a baseline around 300 ng/dL — but lab reference ranges alone can't be the sole determinant of treatment. Bioidentical hormone replacement therapy addresses these imbalances directly.
Although the absolute risks of POME and anaphylaxis require ongoing study, data from 342 patients undergoing 3,022 injections (1,000 mg in 4 mL) over a period of 3.5 years demonstrated that POME occurred after 1.9% of injections (12% of patients experienced at least one POME), with coughing episodes lasting 1-10 minutes in duration.443 All episodes were managed conservatively in the clinic, with no supplemental oxygen required. Further individualization may be considered based on trough testosterone levels at the end of a 10-week injection cycle. Historically, testosterone levels have been measured mid-cycle (day three to four); however, such a measurement protocol misses the ability to define peak and trough levels. Removal of the system results in a rapid drop in testosterone levels.433
Both testosterone and DHT bind to an androgen receptor; however, DHT has a stronger binding affinity than testosterone and may have more androgenic effect in certain tissues at lower levels. In humans, testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. Or, for a more comprehensive check of your hormones, a Male Hormone Test looks at a broader range of male hormones. But perhaps what’s more important is the overall trend of your testosterone level and whether you have symptoms. As more data becomes available, it’s likely that the reference ranges for testosterone will improve to include age-specific values.
TRT can have significant benefits but also comes with potential risks. Testosterone plays a key role in libido and sexual function for both men and women. For this reason, the AUA does not regard technologies or management which are too new to be addressed by this guideline as necessarily experimental or investigational. Guidelines cannot include evaluation of all data on emerging technologies or management, including those that are FDA-approved, which may immediately come to represent accepted clinical practices. Although guidelines are intended to encourage best practices and potentially encompass available technologies with sufficient data as of close of the literature review, they are necessarily time-limited. The physician is encouraged to carefully follow all available prescribing information about indications, contraindications, precautions and warnings.
