Precocious puberty why does it occur?

Early puberty is defined as the occurrence of secondary sexual characters before 8 years of age in girls and 9 years in boys. This definition is somewhat arbitrary because of the large variation in the age at which puberty begins in healthy children, especially in different ethnic groups.

Precocious puberty

In early some secondary sexual characters appear, but there is no activation of the normal hypothalamic-pituitary-gonadal axis. In the latter group, sex characters can be iso sexualize or heterosexual contract sexual early pseudo puberty can induce maturation of hypothalamic – pituitary-gonadal axis and may end up triggering the onset of true sexual precocity.

Dependent Precocious Puberty

The disorder occurs with a frequency of at least 5-10 times higher in girls than in boys and is usually sporadic, although some cases are familial. About 90% of sexual precocity in girls is idiopathic. An abnormality of the central nervous system (CNS) can be demonstrated in 25-75% of children and in 8-10% of girls with central precocious puberty. A high prevalence of idiopathic sexual precocity has been found in adopted girls from developing countries, with the limitations that in some cases the date of birth may be uncertain.

Signs and symptoms

Sexual development can begin at any age and usually follows the sequence observed at normal puberty. In girls, the first sign is breast development pubic hair may appear simultaneously, but usually afterwards.

Precocious puberty consequences

The maturation of the external genitalia, the appearance of maxillary hair and the onset of menstruation follow. Initial menstrual cycles are usually, but a 5.5-year-old pregnancy has been reported. In children, the enlargement of the testicles is followed by enlargement of the penis, appearance of pubic hair and acne. Erections are frequent and nighttime pollution can occur. The voice becomes more serious and linear growth accelerates. Testicular biopsies have shown stimulation of all elements of the testicles, and parthenogenesis has been observed at only 5-6 years of age.

The high rate of bone maturation produces an early closure of the epiphyses and the final size is smaller than it would otherwise have been. Untreated, about one-third of girls and a larger percentage of children reach a lower-than-5th percentile in adulthood. Mental development is generally consistent with chronological age. Emotional behavior and mood swings are common, but serious psychological problems are rare.
