Anabolic steroids, also known as anabolic-androgenic steroids (AAS), are a class of drugs that are structurally related to testosterone, the main male sex hormone, and produce effects by binding to the androgen receptor (AR). Anabolic steroids have a number of medical uses, [ 1] but are also used by athletes to increase muscle size, strength ...
Hyperandrogenism, especially high levels of testosterone, can cause serious adverse effects if left untreated. High testosterone levels are associated with other health conditions such as obesity, hypertension, amenorrhea (cessation of menstrual cycles), and ovulatory dysfunction, which can lead to infertility.
Selective androgen receptor modulators ( SARMs) are a class of drugs that selectively activate the androgen receptor in specific tissues, promoting muscle and bone growth while having less effect on male reproductive tissues like the prostate gland . Non-selective steroidal drugs, called anabolic androgenic steroids (AAS), have been used for ...
Androstenedione, or 4-androstenedione (abbreviated as A4 or Δ4-dione ), also known as androst-4-ene-3,17-dione, is an endogenous weak androgen steroid hormone and intermediate in the biosynthesis of estrone and of testosterone from dehydroepiandrosterone (DHEA). It is closely related to androstenediol (androst-5-ene-3β,17β-diol).
Behavioral endocrinology. Behavioral endocrinology is a branch of endocrinology that studies the Neuroendocrine system and its effects on behavior. [ 1] Behavioral endocrinology studies the biological mechanisms that produce behaviors, this gives insight into the evolutionary past. [ 2] The field has roots in ethology, endocrinology and psychology.
Examples include the lipid cholesterol, sex hormones estradiol and testosterone, [2]: 10–19 anabolic steroids, and the anti-inflammatory corticosteroid drug dexamethasone. [3] Hundreds of steroids are found in fungi, plants, and animals. All steroids are manufactured in cells from the sterols lanosterol (opisthokonts) or cycloartenol (plants
At its peak, during your adolescent years, a normal range for your testosterone is anywhere between 300 and 1,200 ng/dL. When you're entering your mid-30s, you'll start to see it declining by at ...
