If a person is transitioning, they may increase their testosterone levels to make certain aspects of their body — those that society considers masculine — more apparent. Overall, males tend to have higher testosterone levels than females, and females tend to have higher levels of estrogen. During puberty in males, testosterone is responsible for the deepening of the voice, the growth of the male sexual organs, and the development of pubic hair. A doctor may prescribe testosterone replacement therapy if testosterone levels are low due to a medical condition. The men in the study showed significant increases in salivary testosterone under exam stress, while the women had substantially decreased testosterone levels. Low levels of testosterone also affect sexual function, causing reduced sex drive, fewer erections, and infertility.

The effect on your blood pressure may depend on your own health, whether you have any heart disease or high blood pressure, and how much testosterone you take. Similar challenges face other adolescents with chronic illnesses resulting in hypogonadism 100, 101. Recent DMD guidelines call for assessment of puberty as part of a complete exam and appropriate endocrine referral, despite a lack of relevant clinical trials 51, 100. There is little reported on changes in body composition due to T administration. Hypogonadism is linked to low bone mass and an unfavorable metabolic profile characterized by increased visceral adiposity, insulin resistance, and dyslipidemia . Addressing such questions is likely to improve the outcomes of the multiple physiological processes occurring during puberty, such as growth and bone accrual, and affect the psychosocial well-being of the treated adolescent. Once pubertal maturation is complete, the ideal range of serum T concentrations for TRT continuation in a young hypogonadal male is poorly defined. Although there is encouraging evidence for the efficacy of transdermal T therapy (gels and patches), the data are limited 22, 75-77. You may feel more energetic, less depressed, and have a higher sex drive. If your levels are low because of aging, you don't need TRT. Talk to your doctor so you can be weaned off gradually. Taking the drug is often a lifelong commitment (unless the low T is caused by a medical illness), so you'll need to be continually monitored by a doctor. Also, the steroids are often combined ("stacked") with other substances like stimulants, pain relievers, and growth hormones to boost the overall muscle-building effect. These steroids usually contain testosterone or chemicals that act like testosterone. (The word "anabolic" refers to body-building tissue). Some bodybuilders and athletes illegally take anabolic steroids to build muscle mass or to enhance their athletic abilities. Severe disruption to sleep may affect testosterone levels, which could lead to issues with sexual function. In a 2015 study, researchers gave 80 females ages 20– milligrams of fenugreek seed extract or a placebo every day for 8 weeks. For example, one 2015 study showed that taking vitamin D improved sexual function and mood in females with a deficiency. The Food and Drug Administration (FDA) requires testosterone therapy drugs to carry a warning that they may increase the risk of heart attacks and strokes. A person with a testosterone deficiency can also make lifestyle changes that may help increase their testosterone levels. Testosterone is the primary sex hormone in males but also has important functions in females. Testosterone drives libido, production of sperm, distribution of body fat, muscle strength, and creation of red blood cells in males. A sleep study (polysomnography) may be needed to make the diagnosis. This condition can be worsened by testosterone replacement. Men with prostate cancer or elevated prostate-specific antigen (PSA) should probably avoid testosterone treatment. Most experts recommend screening for prostate cancer before starting testosterone replacement. For many men, their prostates grow larger as they age, squeezing the tube carrying urine (urethra). The prostate grows naturally under the stimulation of testosterone.
