Sex steroids – ELEOS

The ELEOS Medical Center is a multidisciplinary center based on a well-known diagnostic laboratory in St. Petersburg "RIAT", which for more than 10 years has provided services to residents of the city in the field of early detection and prevention of a number of diseases deca steroids for sale.

Sex steroids are divided into three main groups:

1. C18 – estrogens with the main representatives – estradiol, estrone, estriol;

2. С19 – androgens with the main representative – testosterone;

3. C21 – gestagens with the main representative – progesterone.

In the female body, the most important sex steroids (i.e., estrogens, gestagens, and androgens) are synthesized in the ovaries and adrenal cortex, and during pregnancy, the placenta. The principal sex steroids for the male body are androgens, which are synthesized in the testes, and in small quantities in the adrenal cortex. All sex steroids and adrenal hormones are cholesterol derivatives.

Estrogens

The most active estrogen in the human body is estradiol, followed by estrone and estriol. Estrogens are produced mainly by ovarian granulosa cells. The secretion of estrogen increases in response to the release of FSH from the pituitary gland.

Serum estradiol

The main representative of estrogens is estradiol, which has the highest biological activity. In the female body, estradiol is synthesized in the ovaries, membrane and granulosa cells of the follicles. At the onset of pregnancy, the massive production of estrogen is carried out by the placenta. Other sites of estrogen synthesis, primarily postmenopausal estrone, include the adrenal cortex and peripheral adipose tissue

Serum estradiol is normal

Children under 11 years old 5-21

Women:

follicular phase 5-53

ovulation phase 90-299 anabolic steroids order online

luteal phase 11-116

changes Increased concentration

Men 19-51

The target organs for estrogen in women are the uterus, vagina, vulva, fallopian (fallopian) tubes, and mammary glands. buy testobolin ampoules online The hormones of this group are responsible for the development of secondary sexual characteristics and determine the characteristic physical and mental characteristics of women. Estrogens cause the epiphyseal growth points to close.

Medications: stilbene, estrogens

Gestagens

Gestagens (progestational steroids) are produced in the ovaries, testes, adrenal cortex, and during pregnancy by the placenta. The action of gestagens is aimed at the implementation of the normal reproductive function of the body. The main representative of this group of hormones is progesterone.

For progesterone to manifest its physiological effect in the female body, preliminary exposure to estrogens is required. The main target organ for progesterone is the uterus.

Androgens

The main representatives of androgens in the female body are testosterone, androstenedione and dehydroepiandrosterone sulfate (DHEA-S). In the body of men, the main representatives of androgens are testosterone and dehydrotestosterone (DHT). In target organs (prostate, seminal vesicles and skin) testosterone acts as a prohormone; this means that testosterone, having best injectable steroids for sale reached the target organ, is converted into DHT, and only after that does DHT exert its biological effect.

Serum testosterone

The content of testosterone in serum is normal: children before puberty – 0.06-0.2 μg / l; women – 0.1-1.1 mcg / l; men 20-39 years old – 2.6-11 μg / l, 40-55 years old – 2.0-6.0 μg / l, over 55 years old – 1.7-5.2 μg / l.

Testosterone is an androgenic hormone responsible for secondary sexual characteristics in men.
