Studies conducted in rats have indicated that their degree of sexual arousal is sensitive to reductions in testosterone. Regular monitoring during treatment typically includes hematocrit levels every 3-6 months to prevent polycythemia, along with PSA monitoring in men over 40. Current clinical guidelines recommend comprehensive baseline evaluation including complete blood count, lipid panel, prostate-specific antigen, and cardiovascular risk assessment before initiating testosterone replacement therapy. It can be administered as a cream or transdermal patch that is applied to the skin, by injection into a muscle, as a tablet that is placed in the cheek, or by ingestion. Testosterone is used as a medication for the treatment of male hypogonadism, gender dysphoria, and certain types of breast cancer. As demonstrated by a meta-analysis, substitution therapy with testosterone results in a significant reduction of inflammatory markers. Attention, memory, and spatial ability are key cognitive functions affected by testosterone in humans.
Time under tension and contraction types (eccentric versus concentric) affect hypertrophy as well.A gradual increase in all of these training variables will yield muscular hypertrophy. Taking additional testosterone, as in anabolic steroids, will increase results.It is considered a performance-enhancing drug, the use of which can cause competitors to be suspended or banned from competitions.Testosterone is also a medically regulated substance in most countries, making it illegal to possess without a medical prescription.Anabolic steroid use can cause testicular atrophy, cardiac arrest, and gynecomastia. that consistent anaerobic strength training will produce hypertrophy over the long term, in addition to its effects on muscular strength and endurance. This method has been shown to induce hypertrophy comparable to traditional high-load training, likely due to mechanical tension and muscle fiber recruitment.|However men with high testosterone were significantly 27% less generous in an ultimatum game. Test subjects with an artificially enhanced testosterone level generally made better, fairer offers than those who received placebos, thus reducing the risk of a rejection of their offer to a minimum. In humans, testosterone appears more to promote status-seeking and social dominance than simply increasing physical aggression. Thus the link between testosterone and aggression and violence is due to these being rewarded with social status. This could explain why some studies find a link between testosterone and pro-social behaviour, if pro-social behaviour is rewarded with social status. One study proposed that natural selection may have caused men to be more sensitive to situations in which their status is challenged, and that testosterone is the key factor that causes these situations to spark into aggression. Studies have found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression.|In fact, testosterone has been shown to effect adipose tissue in humans and in rats, with age being an important co-factor that modulates the effects 30–32. Moreover, both body weight and perirenal fat-mass significantly decreased in 12-month old animals following testosterone depletion. Castration resulted in a significant increase in perirenal fat-pad mass at the same age.

The ATP dependent, 26S subunit, decreased with age in the tibialis anterior, gastrocnemius, and quadriceps muscles, with the age-effect being significant in all muscles (Fig 4A–4C). As protein degradation plays an important role in muscle proteostasis we measured the activity of the 20S and 26S β5 proteasome subunits.}
The levels remain in a pubertal range for a few months, but usually reach the barely detectable levels of childhood by 4–7 months of age. Prenatal androgens apparently influence interests and engagement in gendered activities and have moderate effects on spatial abilities. Specifically, testosterone, along with anti-Müllerian hormone (AMH) promote growth of the Wolffian duct and degeneration of the Müllerian duct respectively. 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.
