Introduction
Girls and boys who suffer from idiopathic sexual precocity, also known as central precocious puberty, experience early sexual development. While boys and girls typically begin puberty between the ages of nine and fourteen and between the ages of eight and thirteen, central precocious puberty affects both genders before the age of nine. Puberty symptoms include the growth of pubic and underarm hair, a sudden increase in height (known as a "growth spurt"), acne, and stench beneath the arms. In addition to getting breasts, girls also start having periods. Boys' penis, testicles, and voice depth develop as they age.
Children who experience central precocious puberty may grow taller than their peers as a result of the early growth spurt, but they may also stop growing unusually early. Some affected people grow to maturity shorter than other family members if they do not receive the right treatment. For those affected, growing emotionally faster than their peers can be challenging and might even result in behavioral and psychological issues.
What Causes Idiopathic Sexual Precocity?
Precocious central puberty frequently has no known reason. MKRN3 gene mutations are the most frequent genetic factor implicated in central precocious puberty. The disorder can occasionally be caused by abnormalities in other genes, and scientists believe that central precocious puberty may also be caused by changes in unidentified genes. In addition to genetics, dietary habits, socioeconomic position, and exposure to specific environmental toxins all have an impact on when a person reaches puberty.
The MKRN3 gene produces a protein that is involved in controlling the beginning of puberty. Puberty begins when the hypothalamus, a brain gland, is triggered to release bursts of the hormone known as a gonadotropin-releasing hormone (GnRH). Other hormones that control sexual development are released due to this hormone. According to studies, the MKRN3 protein prevents (inhibits) the release of gonadotropin-releasing hormone from the hypothalamus, delaying the start of puberty.
It is believed that the MKRN3 gene mutations responsible for central precocious puberty result in the synthesis of an inactive MKRN3 protein. Researchers hypothesize that, even if the exact mechanism is unknown, the absence of the MKRN3 protein, which normally prevents gonadotropin-releasing hormone release from the hypothalamus, causes the onset of puberty to occur earlier than usual.
Additional Factors Include
-
An inheritance of central precocious puberty.
-
An uncommon genetic issue.
-
A benign tumor of the pituitary gland or brain.
-
Brain damage.
-
A brain infection, such as meningitis.
-
Chemotherapy or radiation for the treatment of cancer.
What Are the Symptoms Associated With Idiopathic Sexual Precocity?
The following can appear before the age of eight in girls and before the age of nine in boys, which are premature puberty symptoms.
-
For boys, facial hair as well as hair in the genitals and underarms.
-
Breast growth and first period in girls.
-
Acne.
-
Adults' odor.
-
The growth of the testicles or the development of breast buds.
-
A change in emotions.
-
Mood changes.
-
Children occasionally develop hair on their genitalia and beneath their arms, but this does not necessarily indicate that they are fully mature adolescents.
How Is Idiopathic Sexual Precocity Diagnosed?
It is believed that using the age cutoffs for evaluation will reduce the possibility of overlooking a serious medical issue:
1. Male breast development occurs before pubic hair or testicular growth in boys.
2. In boys, gonadarche, or pubic hair, appears before age nine.
3. The appearance of pubic hair (pubarche) before the age of eight or the beginning of breast growth (the larche) in girls before the age of seven.
4. Girls' menstruation (menarche) before the age of ten.
Sometimes a medical evaluation is required to distinguish the few children with serious issues from the majority of kids who have already reached puberty but are still healthy physiologically. Early sexual development needs to be examined because it could:
1. Promote early bone development and decrease final adult height.
2. Reveal the existence of a tumor or another critical issue.
3. Turn the children, especially a female, into a sexual object for an adult.
In addition to watching for puberty symptoms, they might also:
1. Hormone amounts.
2. Blood testing for bone aging measures hormone levels.
3. If your child's bones are maturing too quickly, X-rays can detect this.
4. Tumors can be ruled out using magnetic resonance imaging or computed tomography scans.
What Are the Treatments Associated With Idiopathic Sexual Precocity?
1. Anastrozole is one therapy option.
2. Other viable treatments include gonadotropin-releasing hormone agonists like Histrelin, Triptorelin, or Leuprorelin. A histrelin implant, which can last up to a year, is another option for treating central precocious puberty. Although it necessitates a minor surgical procedure, this treatment is helpful for central precocious puberty without the discomfort and inconvenience of frequent injections. The implant is inserted beneath your child's skin through a cut on the inside of the upper arm. The implant is removed after a year and, if necessary, replaced with a fresh one.
3. Gonadotropin-releasing hormone agonists stimulate the pituitary gland to release follicle-stimulating hormone (FSH) and luteinizing hormone when used intermittently.
4. Most children with central precocious puberty can be successfully treated with medication if there is no underlying medical issue. This therapy, known as gonadotropin-releasing hormone analog therapy, often entails a monthly injection of a drug that prevents further development, such as Leuprolide acetate or Triptorelin. Longer intervals can be used with some newer formulations. The child continues to take this medicine up until the time that they typically enter puberty. The process of puberty recurs around 16 months after the patient stops taking medicine.
Conclusion
Central precocious puberty. It occurs when the body matures earlier than anticipated, possibly years earlier. Puberty typically begins in girls around the age of eight and in boys around the age of nine. Normal puberty may begin in some kids as early as age six for girls and eight for boys, especially if they are African-American or Hispanic. The onset of puberty symptoms, such as developing breast tissue and body hair, occurs substantially earlier with central precocious puberty. Girls experience it more often.
