PREMATURE SEXUAL DEVELOPMENT

PREMATURE SEXUAL DEVELOPMENT

Premature sexual development is appearance of the second sexual signs and menstruations for girls under age 8.

1. Isosexual form of premature sexual development - the signs of sexual development, that appear for girls.

2. Heterosexual form of premature sexual development - girls have signs, incident to masculine sexual development.

Isosexual premature sexual development can be true and erroneous.

1.1. Veritable premature sexual development (cerebral form) is the state, when structures which are responsible for adjusting of the reproductive system - hypothalamus and hypophysis are involved in a process.

Veritable premature sexual development for girls can have organic and functional character.

1. Organic cerebral premature sexual development - caused the organic defeat of CNS. At the organic defeat of brain premature sexual development, as a rule, develops after appearance or on a background cerebral and neurological symptomatic. Reasons of cerebral premature sexual development:

1. an asphyxia is in births, maternity trauma, hypotrophy of fruit, gestosis;

2. heavy intoxication and infection during the first year of life;

3. cerebral infections like meningitis, encephalitis;

4. brain tumors.

These reasons result in development of internal hydrocephalia- to the stretch and increase of pressure in the ventricles of cerebrum, pressure on hypothalamus, which forms the bottom of Ш ventricle, is the same carried out.

2. Functional cerebral premature sexual development - caused violations of CNS of functional character after carried in the first years of life (2 - 4 years) of infectious diseases, intoxications.

Cerebral premature sexual development runs across as a complete or incomplete form.

3. The complete form of cerebral premature sexual development is characterized development of the second sexual signs and menstruation.

4. The incomplete form of cerebral premature sexual development is characterized the different degree of development of the second sexual signs in default of menstruations.

An incomplete form of premature sexual development is the first phase of period of the sexual ripening stretched as though in time. Меnarche for girls with the incomplete form of premature sexual development comes in 10 - 11 years.

Constitutional form of veritable premature sexual development.

At this form of premature sexual development it is not succeeded to find out neurological, cerebral pathology. Premature is age the process of the sexual ripening begins in which. A rate and sequence of this process is not violated. The inherited character of constitutional premature sexual development appears.

1.2. Ovarial form of premature sexual development.

Ovarial form of premature sexual development is conditioned the secretion of sexual hormones by tumor tissue of ovaries.

1.2.1. Hormonal active tumors of ovaries.

The first symptom of ovarial premature sexual development usually are menstrual-similar excretions of аcyclic character at the poorly developed second sexual signs. Appearance of menstrual-similar excretions from sexual ways for girls under age 8 induces parents immediately to appeal to the doctor. That is why from the beginning of hormonal secretion to the address to the doctor passes tumor tissue little time and the second sexual signs do not have time to develop.
