Subtitles:

1. Hormonal Changes

Adrenarche is characterized by the initiation of hormonal changes in the adrenal glands. These changes lead to increased production and secretion of androgens.

2. Adrenal Maturation

Adrenarche also signifies the maturation of the adrenal glands, which results in the development of their full functionality. This involves the growth and differentiation of adrenal tissue.

3. Androgen Hormones

With the onset of adrenarche, there is an upsurge in the production of androgen hormones, such as dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS). These hormones play important roles in the development of secondary sexual characteristics.

4. Age of Occurrence

Adrenarche typically begins around the age of 6 to 8 years and continues throughout childhood. It precedes the onset of puberty and is considered an early stage of sexual maturation.

5. Physical and Psychological Effects

The hormonal changes during adrenarche can result in noticeable physical and psychological effects. These may include the development of body odor, increased oiliness of the skin and hair, as well as changes in mood and behavior.
