Hormone Steroids Androstenedione is a steroid hormone. It is used for pharmaceuticals.
Hormone Steroids Androstenedione is used to increase hormone testosterone production to enhance exercise capacity and increase energy. Maintain red blood cell health, enhance the movement of recovery and growth, increase sexual desire and performance.
4-androstenedioic acid is described as "hormone" because it itself is very small. On the contrary, it is important because the ability of different parts of the body to convert it into hormones, testosterone and estrogen, which have a lot of impact on the body.
In females, adrenal (called the cortex) and the outer part of the ovaries release 4-androstenedione into the blood, where they are converted to provide about half of the testosterone and almost all the body's estrone, an estrogen form. Although testes produce large amounts of 4-androstenedic acid in men, they are hardly secreted into the bloodstream, but are rapidly converted into testosterone within the testes. The adrenal gland also produces 4-androstenedic acid in males, but this contribution is overwhelmed by testosterone other testosterone testosterone that is repaired by the testes.

|Effect||4-Androstenedione has been shown to increase serum testosterone levels over an eight-hour period in men when taken as a single oral dose of 300 mg per day, but a dose of 100 mg had no significant effect on serum testosterone. However, serum levels of estradiol increased following both the 100 mg and 300 mg doses. The study also reported that the serum level of estrogens and testosterone produced varied widely between individuals.
Because androstenedione can be converted to estrogenic steroids, people taking this supplement may have estrogenic side-effects.
In child development, higher levels of androstenedione in boys have been associated with higher levels of acting out behaviors.
|Usage||4-Androstenedione is further converted to either testosterone or estrogen.
In males, conversion of androstenedione to testosterone requires the enzyme 17-hydroxysteroid dehydrogenase.
In females, androstenedione is released into the blood by theca cells. Conversion of androstenedione to estrogen (e.g., estrone and estradiol) requires the enzyme aromatase. Androstenedione is a substrate for estrogen production in granulosa cells which produce aromatase. Thus, theca cells and granulosa cells work together to form estrogens.
Used for simplified hormone drugs, from the testis or urine extracted with the role of a male hormone steroid, norethisterone, testosterone propionate in the middle body, is widely used in small rheumatoid arthritis, diuretic, and a variety of contraceptive to control infectious inflammation.
4-androstenedione is a common precursor of male and female sex hormones. Some 4-androstenedione is also secreted into the plasma and can be converted into testosterone and estrogen in peripheral tissues.
4-androstenedione can be synthesized in one of two ways. The main pathway involves the conversion of 17-hydroxypregnenolone to dehydroepiandrosterone by 17,20-lyase, followed by conversion of dehydroepiandrosterone to 4-male by enzyme 3-beta-hydroxy steroid dehydrogenase Ene. The secondary pathway involves the direct conversion of 17-hydroxyprogesterone (the most common precursor of cortisol) to the 4-androstenedione by the 17,20-lyase. Thus, the synthesis of 4-androstenedione requires 17,20-cleavage enzymes, either immediately or in one step.
The production of adrenal 4-androstenedione is controlled by ACTH, whereas the production of gonadotropin androstenedione is controlled by gonadotropin. In premenopausal women, the adrenal gland and ovaries each account for about one quarter of androstenedione (about 3 mg / day). After menopause, the production of 4-androstenedione is reduced by about half, mainly due to reduced ovarian secretion of steroids. However, 4-androstenedione is the major steroid produced by postmenopausal ovaries.
How to use it?
4-androstenedioic acid is used to assess the function of the adrenal and ovarian or testis and the production of hormones associated with male sexual organ development and body characteristics (androgen). The most commonly used to determine the level of testosterone levels in women with excessive androgen symptoms, as well as for this purpose of some other laboratory tests.
4-androstenediate levels can be used
Assessment of adrenal function, and to distinguish from ovarian or testicular adrenal gland-induced androgen secretion conditions, if DHEAS and testosterone test results abnormal
Diagnosis of congenital adrenal hyperplasia (CAH) and monitoring of CAH treatment, in addition to testosterone and 17-hydroxyprogesterone test, such as:
Investigation and diagnosis of young girls' male physical characteristics (masculine) and early (early maturing) causes of adolescence
How to control the four male?
Because of its secretion of multiple different glands, and its often quickly converted to other hormones, so the body of the four male male dienone control is very complex. However, it is important to know that the two key components of the brain (hypothalamus and pituitary gland) are important in controlling the secretion of 4-androstenedione in testes, ovaries and adrenal cortex. Is thought to be associated with pituitary gland secretion by specialized hormones that promote adrenocorticotropic hormone - associated adrenal cortex release of 4 - androstenedione. However, it is unclear exactly how corticotropin and other hormones control the production of 4-androstenedione in the adrenal gland. Stimulates testis and ovarian release of 4-androstenedic acid through luteinizing hormone and follicle stimulating hormone. These are released from the anterior pituitary to respond to the hypothalamic hormone signal.
What if I have too much 4-Androstenediones to happen?
The effect of excessive 4-androstenedione may be due to its conversion to estrogen or testosterone in vivo.
