androgen

Examples of androgen in the following topics:

• Pineal Gland and Gonads

  • The testes produce androgens, which allow for the development of secondary sex characteristics and the production of sperm cells.
  • Testosterone, the most prominent androgen in males, stimulates the development and functioning of the primary sex organs .
  • The testes produce androgens, such as testosterone, which regulate primary sex organ development and function, as well as the development of secondary sex characteristics and the production of sperm cells.
  • Male testes produce androgens, while female ovaries produce estrogen and progesterone.

• Hormonal Regulation of the Reproductive System

  • These processes are controlled by the size and frequency of GnRH pulses, as well as by feedback from androgens and estrogens.
  • FSH also enhances the production of androgen-binding protein by the Sertoli cells of the testes by binding to FSH receptors on their basolateral membranes.
  • LH stimulates production of the sex hormones (androgens) by the Leydig cells of the testes.
  • The most widely-known androgen in males is testosterone, which promotes the production of sperm and masculine characteristics.

• Lipid-Derived, Amino Acid-Derived, and Peptide Hormones

  • Examples of steroid hormones include estradiol, which is an estrogen, or female sex hormone, and testosterone, which is an androgen, or male sex hormone.
  • Other steroid hormones include aldosterone and cortisol, which are released by the adrenal glands along with some other types of androgens.

• Adrenal Glands

  • These layers form three distinct regions: an outer zona glomerulosa that produces mineralocorticoids; a middle zona fasciculata that produces glucocorticoids; and an inner zona reticularis that produces androgens, which are sex hormones that promote masculinity.
  • Androgens are produced in small amounts by the adrenal cortex in both males and females.
