Meaning of Testosterone

What is Testosterone:

Testosterone is the main male sex hormone. Its function is the development of the male genitalia, as well as the formation and maintenance of male secondary sexual characteristics.

For more information, see the Hormone article.

The word, as such, comes from the German Testosteron, and is composed with the Latin voice testis, which means 'testicle', and the German -steron, which stands for 'steroid hormone'.

Testosterone is a hormone present in mammals, reptiles, birds, as well as other vertebrates. In the group of mammals, which is the case of humans, this hormone is produced mainly in the testicles of males, but also in the ovaries of females.

The physiological effects of testosterone gradually manifest themselves throughout growth. During the formation of the fetus, testosterone is essential for the development of the male sexual glands, and, later, in puberty and adolescence, until reaching adulthood, it is responsible for the appearance of male secondary sexual characteristics such as, for example, hair growth on the face, pubic and axillary region, increased bone and muscle mass, deepening of the voice, among other things.

In adult men the presence and production of testosterone is considerably higher than in adult women, although it is important to emphasize that they also produce it naturally, since testosterone is an essential hormone for health and well-being.

Testosterone, estrogen and progesterone

Testosterone, estrogen and progesterone have in common, among other things, being sex hormones produced by humans. Testosterone is produced in greater quantity by men and less by women. She is responsible for issues related to male appearance and features, such as underarm, facial and public hair, deepening of the voice or increased muscle mass.

Estrogen, on the other hand, is a hormone produced in greater quantity by women. It is responsible for the appearance of secondary female sexual characteristics, such as the appearance of public and armpit hair, the distribution of body fat that determines the female silhouette, among other things.

Progesterone, for its part, is also a hormone involved in female physiological processes, such as the menstrual cycle, pregnancy or gestation. It develops from puberty and adolescence.

Testosterone and its therapeutic use

Testosterone also has a therapeutic use in men whose testosterone production levels are low or null (hypogonadism), in hormone replacement treatments in order to maintain testosterone levels within the normal range. It is also used for other conditions, such as infertility, lack of libido, erectile dysfunction, osteoporosis, height growth, among other things.
