The age of menarche, for example, varies among countries and even among different cultures within one country.
" Concrete-operational children may be able to solve an analogous problem (e.g., one using sticks of various lengths, with the sticks actually present). *** enlargement patches are one of the latest methods to hit the market. In males, there is a continuing enlargement of the testicles, an enlargement and reddening of the scrotal sac, and an increase in the length and circumference of the ***. In females the vulva and clitoris enlarge; in males the testes continue to enlarge, the scrotum grows and becomes pigmented, and the *** becomes longer and increases in circumference. In regard to secondary sexual characteristics, in females there is increased breast development, with the breast buds enlarging to form the primary breast; in males, the voice deepens and pigmented axillary and facial hair appear, usually about two years after the emergence of pubic hair. Secondary sexual characteristics are those that emerge during the prepubescent through postpubescent phases (e.g., *** in females and pigmented facial hair in males). This so-called growth spurt occurs about two years earlier in females than in males. Another key change of pubescence in females is menarche, or the onset of menstruation, which occurs about 18 months after the maximum height increase of the growth spurt and typically is not accompanied initially by ovulation.
