• In women, therapy should stay within the female physiologic range and is supported for much narrower indications. In general, guidelines aim for symptom improvement within the normal physiologic male range rather than supraphysiologic levels (Bhasin et al., Journal of Clinical Endocrinology & Metabolism, 2018). If testosterone rises above the female physiologic range, the risk of androgenic adverse effects increases and the treatment logic starts to break down (Parish et al., Climacteric, 2021; Parish and Kling, Menopause, 2023). Testosterone therapy in women has a much narrower evidence-based indication, with the strongest support in postmenopausal women with hypoactive sexual desire disorder (Davis et al., Journal of Sexual Medicine, 2019; Parish et al., Climacteric, 2021). In healthy nonobese men aged 19 to 39, harmonized reference work identified an approximate normal range of 264 to 916 ng/dL, with a median near 531 ng/dL. For men, the goal is usually to bring testosterone into the normal range for healthy men and match that to clinical response.

If your results show high testosterone levels, it might be worth meeting with your doctor to confirm the results through a physician-ordered blood test and to discuss your next steps. Keep in mind that average testosterone levels decrease with age. In adult males, the average testosterone range will depend on a person’s age. For males under age 45 years, a testosterone test is usually performed in the morning when T levels are highest.
However, according to the American Urology Association, men with levels below 300 ng/dL should be classified as having low T, or hypogonadism. A saliva test may be an alternative if you experience difficulties with needles or blood samples. Sometimes, the test needs to be retaken to confirm the measurements. While these tests can be good for initial screening, a physician-ordered blood test will offer the most accurate results. There are several companies offering simple, at-home testosterone tests that can deliver results in just a few days.

Women may have a testosterone deficiency due to diseases of the pituitary, hypothalamus or adrenal glands, in addition to removal of the ovaries.
Researchers from the Shanghai University of Sport monitored 15 male boxers during three weeks of high-intensity training and three weeks of high-volume training sessions, separated by four weeks of rest.
