However, the majority of testosterone produced in the ovaries is converted to the primary female sex hormone, estradiol. Healthcare providers use synthetic testosterone to treat and manage various medical conditions. If testosterone levels are too high or too low, it can cause certain symptoms. In a study published in the European Journal of Applied Physiology, it elevated testosterone levels in middle-aged men – and prevented it from declining during HIIT workouts.

However, several studies have confirmed that saliva offers only a relatively accurate measurement of testosterone levels. These blood tests can be administered by a medical professional in a lab, or through an at-home testosterone test kit, which requires you to mail your test sample to a lab for analysis. Women with high testosterone levels, due to either disease or drug use, may experience a decrease in breast size and deepening of the voice, in addition to many of the problems men may have. Blood levels of testosterone vary dramatically over time and even during the course of a day. While the specifics are uncertain, it's possible that androgens also play an important role in normal brain function (including mood, sex drive and cognitive function).

However, the optimal amount of testosterone is far from clear. It’s important to note that for people assigned female at birth (AFAB), there’s no exact number for determining high testosterone levels, also known as hyperandrogenism. In comparison, normal testosterone levels for men ages 19 years and older are typically between 240–950 ng/dL. Like other hormone types, there’s a chance that someone can have abnormal testosterone levels. After menopause, typically between the ages of 45 and 55 years, testosterone levels in females decrease significantly. At this time there are no age-specific testosterone reference ranges for males or females. If the levels aren’t within a standard range, you can discuss potential treatment options, including testosterone replacement therapy. In females, testosterone levels also begin to drop more rapidly after age 30 years and are significantly reduced postmenopause.

From the age of 30 onwards, your T-levels start to decline at a rate of 1% each year. The proper balance between testosterone (along with other androgens) and estrogen is important for the ovaries to work normally. For example, the genitals may not enlarge, facial and body hair may be scant, and the voice may not deepen normally. Adolescent boys with too little testosterone may not experience normal masculinization. A "feedback loop" closely regulates the amount of hormone in the blood. They travel from one organ or another place in the body, usually through the bloodstream, and affect many different bodily processes.
