Adrenarche is a lot like puberty; it’s characterized by changes in the body as your child enters her teen years. Premature adrenarche is when these changes begin early, before age 8 for girls and age 9 for boys. It’s usually nothing serious, simply your child’s body maturing in its own time.
What happens during Adrenarche?
Adrenarche refers to the time during puberty when the adrenal glands increase their production and secretion of adrenal androgens.
