Document Summary

Puberty begins years before there are any awkward signs it always starts at night (nobody knows why) Bannatrophins carry signals from the brain to the rest of the body (male in the video) cells begin to divide in his testicles which will one day produce sperm. By the time the boy is 13 he has gained enough testosterone that his body has begun to change into that of a man. Inside the boys brain testosterone seeps from blood vessels into the uid that surrounds his brain it will soon transform his mind. Inside his brain testosterone soaks through the membranes of dormant cells triggering a chemical reaction it brings to life a group of interconnected brain cells which is his reproductive circuit and gives him the desire for sex. Over the past 5 years the girls brain has been just as active as the males. Gonanatrophoins bring to life her ovaries, so that the eggs begin to mature.
