Testosterone is one of the important androgenic hormones secreted in both men and women. What is its role? What are its effects? How can it be increased? Here’s how it works.
Testosterone is a male hormone secreted in part by the adrenal glands (located above the two kidneys) and the sex organs. Often considered the sex hormone, it actually has many roles in the body. It circulates in the blood in two forms: total and bioavailable. The first is bound to the SHBG protein and has little effect on the body, while the second is free and usable by the body.
Pri ženskah: This hormone, synthesised partly by the adrenal glands and in small quantities by the ovaries, plays a role in sexual desire.
Pri moških: Testosterone is produced by both the adrenal glands and the Leydig cells in the testicles. It is involved in the development of male physical characteristics such as the maturation of the genitals, hair growth and voice development. It plays a role in spermatogenesis (maturation of spermatozoa), libido, muscle mass and bone development. Finally, it is involved in mood.
In men, a blood test may be prescribed to look for testicular or pituitary dysfunction, particularly in the presence of signs such as libido problems and sexual problems such as erectile dysfunction.
In women, it can be prescribed when there are symptoms suggesting an excess of this hormone: acne, oily skin and hair. But also when there is excessive hair growth in areas that are not usually hairy, such as the moustache, chin or breasts (hirsutism).
Normal testosterone levels depend on gender and age.
- Between the ages of 1 and 10: < than 0.7 nmol/l,
- Between the ages of 10 and 20: between 1.7 and 17.5 nmol/l,
- Between the ages of 20 and 45: between 10 and 30 nmol/l,
- Between the ages of 40 and 60: between 7 and 28 nmol/l,
- Between the ages of 60 and 75: between 3.5 and 17.5 nmol/l.
- After 75 years of age, the levels drop to between 0.4 and 9 nmol/l.
In women, normal testosterone blood levels are ten times lower. Thus:
- Between the ages of 1 and 10: < than 0.5 nmol/l,
- Between the ages of 10 and 20: between 0.5 and 3.4 nmol/l,
- Between the ages of 20 and 45: between 0.5 and 3.1 nmol/l,
- Between the ages of 45 and 60: between 0.5 and 2.8 nmol/L,
- After 60, it drops to between 0.3 and 1.70 nmol/l.
Too low a level
In men, this is called hypogonadism. This occurs in cases of testicular insufficiency, andropause, Cushing’s syndrome, chemotherapy or radiation as part of cancer treatment, or when taking synthetic androgens, oestrogens or anti-androgens. In women, it may decrease in the case of Feminizing Testicular Syndrome (androgen insensitivity).
Too high a level
In men, this may be indicative of the intake of synthetic testosterone, which is generally used by some men, often sportsmen, to benefit from its anabolic role and to increase their muscle mass. But hyperthyroidism can also be involved. In women, it can increase in the case of hirsutism, polycystic ovaries, ovarian or adrenal tumours.
Lack of testosterone: how to increase it
When testosterone levels are too low, supplementation can be considered in order to compensate the level and thus correct the symptoms that led to the testosterone level being measured.
Hormonal stimulants based on natural nutrients such as certain amino acids or exotic ingredients (Maca, Ginseng, Ginkgo Biloba, …) can help. The best known is TestoUltra. This product has no side effects and influence the existing hormone levels, making them more available for muscles and strength. They even stimulate endogenous secretion. So, to safely increase your testosterone levels, you can rely on this natural testosterone booster: Kupite TestoUltra.
