Precocious puberty is a rare disease but is becoming more common in children today. About 1 out of 5000 children is affected by this disease. Precocious puberty can begin as early as three or four for girls and five or six for boys. Also, it is most common in African American girls. Studies show that children who are adopted from overseas are 10-20 times more likely to develop precocious puberty. Not all children diagnosed with precocious puberty need to be treated. This disease can have lifelong health risk for girls and boys. Girls are ten times as likely to have central precocious puberty then boys. These are some interesting facts I found on http://kids.org/ parent/medical/sexual/precocious.html. There are many interesting facts about precocious puberty including: the types, causes, and signs; the clinical and social significance and isosexual and heterosexual; and the treatments and consequences. To begin with, there are two kinds of precocious puberty central and peripheral. Central precocious puberty is the more common of the two. Gonadotropins are hormones that are produced by the pituitary glands; these hormones stimulate the testicles or ovaries to make other hormones. And the changes of puberty, like breast development in girls, are caused by these hormones. Central precocious puberty often causes children’s bones to feel older than usual. Children with this diagnosis can reproduce early making them fertile an able to have children as early as they start puberty. Peripheral precocious puberty is a secondary sexual development induced by sex steroids from other abnormal sources. Peripheral precocious puberty has nothing to do with the brain or pituitary glands; it’s a local problem with the ovaries, testicles, adrenal gland, or a severely underactive thyroid gland. Also these facts stated are found on http://kids.org/parent/medical/sexual/precocious.html. Next, the cause of central precocious puberty are: hereditary, medical problems, damage to the inhibitory system of the brain (from infection), trauma or irradiation, hypothalamic hematoma (produces pulsatile gonadotropin-releasing hormones), Langerhans cells histiocytsis, McCune-Albright syndrome, and environment exogenous hormones. The causes for peripheral precocious puberty include: gonadal tumors, germ cell tumors, congenital adrenal hyperplasia, McCune-Albright syndrome, and environment exogenous hormones. On http://enwikipedia.org/wiki/precocious_puberty I found that exposure to chemicals that mimic estrogen (known as xenoestrogens) is a possible cause of early puberty in girls. Bisphenol A, a xenoestrogen found in hard plastics has been shown to effect sexual development. Girls are starting puberty at an earlier age and boys are starting at a later age. Obese females usually start to develop breasts and tend to start menstruate at an earlier age. Then signs of precocious puberty in females are breast development and menstruation. Signs for males include: growth of the testicles, penis, and scrotum; facial and underarm hair, and a deepening voice. Also growth spurts are another sign for males and females. In addition, there are some clinical and social significance. Also found on http://enwikipedia.org/ wiki/precocious_puberty early sexual development can induce early bone maturation and reduce eventual adult height; indicate the presence of a tumor or other serious problems; and cause the child particularly girls, to become a sexual object. Also, early puberty can put girls at a higher risk for mental health disorders, and teasing or bullying. Breast cancer is another possible risk for children with precocious puberty. Although boys don’t have as many problems as girls they still have some. Aggressiveness is more common in boys because of the surge of hormones that affect them. Studies show boys that have precocious puberty are more likely to be sexually active and put at risk for...
