Testosterone is the male hormone from the androgen group and is found in humans and other vertebrates. In humans and other mammals, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. Small amounts are also secreted by the adrenal glands. It is the principal male sex hormone. In men, testosterone plays a key role in the development of male reproductive tissues such as the testis and prostate as well as promoting secondary sexual characteristics such as increased muscle, bone mass, and the growth of body hair. In addition, testosterone is essential for health and well-being as well as the prevention of osteoporosis.
The production of testosterone is 20 times greater in men than in women.
Testosterone is necessary for normal sperm development. It activates genes in Sertoli cells, which promote differentiation of spermatogonia. Testosterone Regulates acute HPA (Hypothalamicpituitaryadrenal axis) response under dominance challenge. Other Biological uses are:
- Regulator of cognitive and physical energy
- Maintenance of muscle trophism
- Testosterone regulates the population of thromboxane A2 receptors on megakaryocytes and platelets and hence platelet aggregation in humans.
- High androgen levels are associated with menstrual cycle irregularities in both clinical populations and healthy women.
Cancer prevention and health risks
Testosterone does not cause deleterious effects in prostate cancer. In people who have undergone testosterone deprivation therapy, testosterone increases beyond the castrate level have been shown to increase the rate of spread of an existing prostate cancer.
Recent studies have shown results concerning the importance of testosterone in maintaining cardiovascular health. Maintaining normal testosterone levels in elderly men has been shown to improve many parameters that are thought to reduce cardiovascular disease risk, such as increased lean body mass, decreased visceral fat mass, decreased total cholesterol, and glycemic control.
Men whose testosterone levels are slightly above average are less likely to have high blood pressure, less likely to experience a heart attack, less likely to be obese, and less likely to rate their own health as fair or poor.
Not to long ago I wrote an artcle titled “How to Increase Your Testosterone Levels” which goes into learning how to increase testosterone levels through exercise and diet for men. we are living in a time where many men as young as 22 are suffering from low levels of testosterone. For many, proper exercise and nutrition is not enough. The next step would be to go to your doctor and get some blood word done to see where the problem lies and have your doctor prescribe testtosterone therapy. This process will help in correcting the imbalace that may exist with your hormonal system.
Read my two important articles on “How to lower estrogen levels in men” and “How to Increase Your Testosterone Levels.” These two articles will give you a complete plan of action on what to do to help with testosterone levels for men.
Until Next Time,
God bless you all.
