key term - Adrenal androgens

Definition

Adrenal androgens are hormones produced by the adrenal glands, specifically the zona reticularis of the adrenal cortex. They play a significant role during adolescence and puberty by contributing to the development of secondary sexual characteristics and influencing sexual maturation. These hormones, such as dehydroepiandrosterone (DHEA), are essential for both males and females, affecting not only physical traits but also mood and energy levels.

5 Must Know Facts For Your Next Test

  1. Adrenal androgens peak during late adolescence and play a crucial role in the growth spurt associated with puberty.
  2. These hormones can influence psychological aspects, such as mood swings and increased aggression during adolescence.
  3. In females, adrenal androgens contribute to the development of pubic and axillary hair as well as libido.
  4. DHEA is one of the most significant adrenal androgens, often referred to as a 'parent hormone' because it can be converted into more potent sex hormones like testosterone and estrogen.
  5. An imbalance of adrenal androgens can lead to conditions such as precocious puberty or adrenal hyperplasia.

Review Questions

  • How do adrenal androgens contribute to physical development during puberty?
    • Adrenal androgens are crucial during puberty as they promote the development of secondary sexual characteristics such as body hair growth, increased muscle mass, and changes in fat distribution. They are produced in higher amounts during this time, especially in the late stages of adolescence, contributing significantly to the physical transformation that occurs as individuals transition into adulthood. Both males and females experience these changes, although the effects may differ between genders.
  • Discuss the role of adrenal androgens in both male and female adolescents regarding sexual maturation.
    • In male adolescents, adrenal androgens contribute to early stages of sexual maturation by supporting testosterone production, which drives the development of male sexual characteristics. For females, these hormones are involved in the onset of puberty by stimulating growth of pubic and underarm hair as well as influencing libido. Both genders rely on these hormones for proper sexual development, although their effects manifest differently across sexes.
  • Evaluate how an imbalance in adrenal androgens can impact adolescent health and development.
    • An imbalance in adrenal androgens can lead to various health issues during adolescence. For instance, excess production may result in conditions like precocious puberty or polycystic ovary syndrome (PCOS) in females, while inadequate levels can delay puberty or affect sexual development in both sexes. Such imbalances can also influence psychological health, potentially leading to mood disorders or behavioral issues. Therefore, monitoring adrenal androgen levels is essential for ensuring healthy adolescent growth and development.
