A gene's first 'kiss' sets off that affair known as puberty

...productive system in common with the human's. The onset of puberty becomes official when gonadotropin-releasing hormone (GnRH) is secreted and sets off a chain reaction of chemical messages. Inside the hypothalamus, nerve cells release GnRH in a 'round-the-clock,' pulsatile fashion. With each secretion, t...
