Major sources of androgen in females are all except :
**Core Concept**
In females, androgens play a crucial role in various physiological processes, including the development of secondary sexual characteristics and the maintenance of bone density. The major sources of androgens in females include the adrenal glands, the ovaries, and peripheral tissues.
**Why the Correct Answer is Right**
The adrenal glands produce androgens, such as dehydroepiandrosterone (DHEA) and its sulfate (DHEAS), which are then converted to more potent androgens like testosterone and dihydrotestosterone (DHT) in peripheral tissues. The ovaries, although producing more estrogen, also produce small amounts of androgens, including androstenedione, which is converted to testosterone in peripheral tissues. Peripheral tissues, including the skin and hair follicles, also produce androgens through the conversion of precursor hormones.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is not provided, but it would be incorrect if it listed a source of androgens in females that is not actually a major source.
**Option B:** This option is not provided, but it would be incorrect if it listed a source of androgens in females that is not actually a major source.
**Option C:** This option is not provided, but it would be incorrect if it listed a source of androgens in females that is not actually a major source.
**Option D:** This option is not provided, but it would be incorrect if it listed a source of androgens in females that is not actually a major source.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that androgens play a vital role in the maintenance of bone density in females, and their deficiency can contribute to conditions like osteoporosis. The conversion of androgens in peripheral tissues is mediated by the enzyme 17β-hydroxysteroid dehydrogenase.
**Correct Answer:** None of the above
