The Pineal Gland is an endocrine gland and secretes many different hormones durning childhood. In fact it is quite large in children and very active. Melatonin is one of its major hormones it secretes and is believed to slow the process of puberty. Testosterone or Estrogen is believed to signal the reduced secretion of melatonin thus eventually leading to full sexual development.
