When we grow up, we all look fairly similar. The human body grows and changes during our whole life, but at a certain age a lot of things happen in only a few years, usually between 10 and 13 years of age, during puberty. In this humorous, animated film we will learn more about what happens when you hit puberty: the pituitary gland, body changes, ovulation and ejaculation, pubic and body hair, acne, sweat, erections, masturbation, voice changes, the reproductive system, menstruation, hormones, and social and emotional changes.
