Gonadotropin-Independent Precocious Puberty

|
What is gonadotropin-independent precocious puberty?
Early secretion (also called hypersecretion) of high levels of the body's sex hormones, androgen (male sex hormones) and estrogen (female sex hormones), can lead to the early outward appearance of puberty. Sometimes called pseudoprecocious puberty, this form of early puberty is characterized by the development of most secondary sexual characteristics, although the sexual glands remain undeveloped.
What causes gonadotropin-independent precocious puberty?
The production of high levels of sex hormones in the young child forces the onset of puberty characteristics.
What are the symptoms of gonadotropin-independent precocious puberty?
The following are the most common symptoms of gonadotropin-independent precocious puberty. However, each child may experience symptoms differently. Although the sexual glands themselves remain immature, hypersecretion of androgen and estrogen cause the development of most other secondary sexual characteristics. Symptoms may include:
- girls:
- development of breasts
- underarm and pubic hair growth
- changes in body odor
- boys:
- facial, underarm, and pubic hair growth
- lengthening of penis
- appearance becomes more masculine
- changes in body odor
- acne
The symptoms of gonadotropin-independent precocious puberty may resemble other problems or medical conditions. Always consult your child's physician for a diagnosis.
How is gonadotropin-independent precocious puberty diagnosed?
In addition to a complete medical history and physical examination, diagnosis of gonadotropin-independent precocious puberty may include:
- x-ray - a diagnostic test which uses invisible electromagnetic
energy beams to produce images of internal tissues, bones, and organs
onto film.
- measurement of blood hormone levels
- ultrasound (Also called sonography.) of the adrenal glands and pelvis
a diagnostic imaging technique which uses high-frequency sound waves and
a computer to create images of blood vessels, tissues, and organs. Ultrasounds
are used to view internal organs as they function, and to assess blood
flow through various vessels.
- magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.
Treatment for gonadotropin-independent precocious puberty:
Specific treatment for gonadotropin-independent precocious will be determined by your child's physician based on:
- your child's age, overall health, and medical history
- extent of the condition
- your child's tolerance for specific medications, procedures, or therapies
- expectations for the course of the condition
- your opinion or preference
The goal of treatment for the hypersecretion of androgen and estrogen is to stop, and possibly reverse, the onset of early puberty symptoms. Treatment may include the use of certain medications that inhibit the action of the sex hormones. If a tumor is causing the disorder, surgical removal may be necessary.
