Testosterone - primary male hormone and anabolic steroid Like 0 Twitter Charlesa Gibson Follow Aug. 7, 2018, 3:24 a.m. in Life and Styles Views: 1013 Like us on facebook Today I would like to introduce you basic steroid hormone testosterone Testosterone is the primary male sex hormone and an anabolic steroid. In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair. In addition, testosterone is involved in health and well-being, and the prevention of osteoporosis. Insufficient levels of testosterone in men may lead to abnormalities including frailty and bone loss. The Effects of Testosterone on the Body Testosterone is an important male hormone. A male begins to produce testosterone as early as seven weeks after conception. Testosterone levels rise during puberty, peak during the late teen years, and then level off. After age 30 or so, it’s normal for a man’s testosterone levels to decrease slightly every year. Endocrine System The body’s endocrine system consists of glands that manufacture hormones. The hypothalamus, located in the brain, tells the pituitary gland how much testosterone the body needs. The pituitary gland then sends the message to the testicles. Most testosterone is produced in the testicles, but small amounts come from the adrenal glands, which are located just above the kidneys. In women, the adrenal glands and ovaries produce small amounts of testosterone. Sexuality During puberty, rising levels of testosterone encourage the growth of the testicles, penis, and pubic hair. The voice begins to deepen, and muscles and body hair grow. Along with these changes comes growing sexual desire. There’s a bit of truth to the “use it or lose it” theory. A man with low levels of testosterone may lose his desire for sex. Sexual stimulation and sexual activity cause testosterone levels to rise. Testosterone levels can drop during a long period of sexual inactivity. Low testosterone can also result in erectile dysfunction (ED). Central nervous system Testosterone influences the brain via organizational and activational effects. Numerous relevant studies on rodents and a few on humans focusing on specific behavioral and cognitive parameters have been published. The results are, unfortunately, controversial and puzzling. Dosing, timing, even the application route seem to considerably affect the outcomes. In addition, the methods used for the assessment of psychometric parameters are a bit less than ideal regarding their validity and reproducibility. Metabolism of testosterone contributes to the complexity of its actions. Reduction to dihydrotestosterone by 5-alpha reductase increases the androgen activity; conversion to estradiol by aromatase converts the androgen to estrogen activity. Recently, the non-genomic effects of testosterone on behavior bypassing the nuclear receptors have attracted the interest of researchers. This review tries to summarize the current understanding of the complexity of the effects of testosterone on brain with special focus on their role in the known sex differences. Reproductive system Currently, there is little evidence to suggest that the development of low resting testosterone levels in men doing endurance training has any major detrimental effect on the testosterone-dependent physiological processes of the body. There is the potential for disruption in any of the processes influenced by testosterone, and obviously reproductive capacity is of key concern. Few studies have systematically studied this issue and currently only a few reports of decreased spermatogenesis or oligospermatic conditions existing in endurance trained males have been published. Additionally, some investigators have reported endurance trained men may have a lowered sex drive; but a direct cause-and-effect linkage between a lower sex drive and testosterone did not exist in these data.
