It would eliminate possibility and regulations and developments. Hence, the puberty mechanism should be connected with changes of a condition of the regulator, that is . So it also is. In a number of researches it has been shown that the sensitivity threshold changes during all life. Soon after a birth possesses the maximum sensitivity to braking action of sexual hormones. Therefore the sexual centre during this period is braked by that small amount of sexual hormones which are already developed by an unripe organism.
