Precocious puberty in a child less than 3 years of age is usually gonadotropin dependent and is often associated with extrasellar central nervous system disorders. By definition, puberty is "precocious" when sexual maturity begins before the age of 8 years in girls and 9 years in boys. Precocious puberty often can be treated effectively or controlled with medications that decrease the overproduction of sex hormones or that block their effects on the body. In many cases, no cause can be found for the disorder. A synthetic hormone called histrelin acetate was recently approved to treat central, or unexplained, precocious puberty, in which young children develop the sexual characteristics of adolescents. com/greenglob. The Pituitary Gland: The "Master Gland" The pituitary gland, which is often referred to as the "master gland", regulates the release of most of the body's hormones (chemical messengers that send information to different parts of the body).

In children, the most common symptom (when present) is precocious puberty. The article presents the case of 7½-year-old African American girl, who was diagnosed for rapidly progressing precocious puberty in the U. Medically, it is known as gonadotropin-dependent precocious puberty. In very few cases, if the girl is extremely young or puberty rapidly progresses, it may make sense to consider medicating with GnRH analogs, which block GnRH and halt the progress, as very early development can prevent a full growth spurt from occurring and leave the child with a short stature.

Although precocious puberty has standard clinical definitions and diagnostic tests are improving, the management of children who have signs of early puberty has become more complex in some ways during the last decade than ever before.

Any child entering puberty before the age of 8 in girls or 9 in boys, should be seen by. The child — who was assigned male at birth — identifies as female; has an affirming mother, and a non-affirming father. Because of trends towards earlier pubertal development, some healthy girls will have breast or pubic hair development before this age, and extensive evaluation and treatment may not be required. Girls who develop precocious puberty need to be continually monitored for low levels of thyroid hormones.

A secular trend toward earlier puberty has now been confirmed by recent studies in both the United States and Europe. Screening for mutations of MKRN3 in sporadic cases of central precocious puberty, which affects primarily girls, will add information about the role of this gene in pubertal timing. Causes Sometimes a tumor or other abnormality in the pituitary or hypothalamus can cause the condition, but this only accounts for about 20 percent of the cases of precocious puberty in girls over the age of six.

Non-cancerous adrenal gland tumors can lead to rare cases of Cushing's syndrome in young children and puberty starting years before it should, a case study of a 5-year-old boy shows. Since the LH receptor is a member of the family of G protein-coupled receptors, they hypothesized that male-limited precocious puberty might be due to a mutant receptor that is activated in the presence of little or no agonist.

In some cases, the pituitary gland, which regulates the release of most of the body's hormones, signals the ovaries and testicles to begin hormone production prematurely.
