Cortisol

Cortisol (cortisol; not to be confused with cortisone (cortisone), the inactivated form of cortisol) is a hormone synthesized in the zona fasciculata of the adrenal cortex and belongs to the glucocorticoid group. It is regulated by higher-level hormones such as ACTH (adrenocorticotropic hormone). It has its function mainly effects on carbohydrate balance (promotion of gluconeogenesis … Cortisol

Dehydroepiandrosterone (DHEA Hormone)

Dehydroepiandrosterone (DHEA; more specifically 5,6-didehydroepiandrosterone, also known as androstenolone or androst-5-en-3β-ol-17-one, as well as prasterone) is a weak male sex hormone (steroid hormone) produced in the adrenal cortex (zona reticularis). The formation of DHEA is stimulated here by adrenocorticotropic hormone (ACTH), which is secreted by the pituitary gland. In women, DHEA is additionally synthesized (20-30%) … Dehydroepiandrosterone (DHEA Hormone)

Dehydroepiandrosterone Sulfate (DHEAS)

Dehydroepiandrosterone sulfate (DHEAS) is a male sex hormone produced in the adrenal cortex and belongs to the group of androgenic 17-ketosteroids.In women, DHEA is additionally synthesized 20-30% in the ovaries and 10% by peripheral conversion.DHEA, like the other sex hormones, is synthesized from cholesterol and metabolized (metabolized) to DHEA-S in the liver. It is not … Dehydroepiandrosterone Sulfate (DHEAS)

Dexamethasone Long Test

Dexamethasone is an active substance from the glucocorticoid group.Dexamethasone has a small amount of mineralocorticoid properties. It is among the potent glucocorticoids. The dexamethasone long test(high-dose test) describes a test procedure (dexamethasone inhibition test;dexamethasone suppression test) to determine whether there is a decrease in endogenous cortisol concentration after glucocorticoid ingestion. Procedure Material Needed Blood serum … Dexamethasone Long Test

Dihydrotestosterone

Dihydrotestosterone (DHT; more precisely 5α-dihydrotestosterone (5α-DHT), also called androstanolone (INN)) is a hormone from the group of androgens (male sex hormones). It is an active metabolite (intermediate or breakdown product) of testosterone and is actually a more potent androgen because it binds more strongly to the androgen receptor than testosterone. Dihydrotestosterone is formed in the … Dihydrotestosterone

Free Testosterone

Testosterone is the male sex hormone, which in men is produced in about 95% in the Leydig cells of the testis and 5% in the adrenal cortex.In women, the production occurs predominantly in the adrenal cortex.Testosterone is synthesized from cholesterol. It is one of the fat-soluble hormones. More than 40 percent of it is bound … Free Testosterone

Insulin-like Growth factor-I (IGF-I, SM-C)

Insulin-like-growth-factor-I (IGF1; IGF-I; also called somatomedin C (SM-C)) is a laboratory parameter that shows high similarity to insulin. It is one of the differentiation and growth factors. The majority of IGF-1 is synthesized in the liver. IGF-1 is bound to special binding proteins (insulin-like-growth-factor-binding-protein – IGFBP) that circulate in the blood. In this process, the … Insulin-like Growth factor-I (IGF-I, SM-C)

Insulin-like Growth Factor-Binding Protein-3 (IGFBP-3)

Insulin-like-growth-factor-binding-protein-3 (IGFBP-3) binds insulin-like-growth-factor (IGF-1) circulating in the blood. In this process, the action of IGF-1 is regulated by IGFBP-3. IGF-1 (somatomedin C) is one of the differentiation and growth factors. The synthesis of IGFBP-3 takes place STH-dependently in the liver. Serum IGFBP-3 levels indicate the release of growth hormone over several days: Serum IGFBP-3 … Insulin-like Growth Factor-Binding Protein-3 (IGFBP-3)

Leptin

Leptin (Lept; Greek: leptos = thin) is a satiety hormone synthesized (produced) mainly by adipocytes (“fat cells”). Serum leptin levels correlate positively with body fat mass (KFM) and BMI (body mass index – also called body mass index (BMI)). It is also produced in small amounts in the placenta (placenta) the mammary epithelium, bone marrow, … Leptin

Melatonin: Uses, Effects, Side Effects, Dosage, Interactions, Risks

Melatonin (N-acetyl-5-methoxytryptamine) is a hormone synthesized in the pineal (pineal) gland in the brain from tryptophan via the intermediate serotonin. Melatonin controls the day-night rhythm. It is only synthesized at night. The maximum production is between two and four o’clock. Daylight inhibits production, so it is released in a pulsatile manner. Melatonin is metabolized in … Melatonin: Uses, Effects, Side Effects, Dosage, Interactions, Risks

Estriol (E3)

Estriol (E3; estriol) is the natural form of the female sex hormone. It is formed from estradiol. Unlike estradiol, estriol dissociates quickly from the receptor, which means it is only weakly effective and has a short half-life. It is used primarily to assess the fetoplacental unit in pregnancy. The procedure Material needed Blood serum Preparation … Estriol (E3)

HCG Test

The HCG test (synonyms: HCG stimulation test; Leydig cell function test) is a procedure that determines the function of Leydig cells. Leydig cells are localized in the testis (interstitial cells of the testis/testicular interstitial cells) and produce the gonadal hormones androstenedione and testosterone. In this test, HCG (human chorionic gonadotropin) is stimulated to check the … HCG Test
