  Precocious puberty is when the signs of puberty start: before age 7 or 8 in girls […] before age 9 in boys. It can be hard for some kids and sometimes is a sign of a health problem. […] In girls, signs of precocious puberty include: breast development before age 7 or 8 […] start of menstruation (her period) before age 10 […] rapid height growth (a growth spurt) before age 7 or 8. […] In boys, the signs of precocious puberty before 9 years of age include: enlargement of the testicles or penis […] rapid height growth (a growth spurt). […] When puberty ends, growth in height stops. Because their skeletons mature and bone growth stops at an earlier age than normal, kids with precocious puberty that’s not treated usually don’t reach their full adult height potential. […] Going through puberty early also can be hard for kids emotionally and socially. Girls with precocious puberty, for example, may be confused or embarrassed about getting their periods or having enlarged breasts well before any of their peers.

  Even emotions and behavior may change in kids with precocious puberty. Girls can become moody and irritable. Boys can become more aggressive and also develop a sex drive inappropriate for their age. […] To diagnose precocious puberty, the doctor may order blood tests to look for high levels of sex hormones. X-rays of your child’s wrist and hand can show whether the bones are maturing too early. […] If your child has precocious puberty, the doctor may refer you to a pediatric endocrinologist for treatment. The treatment goals are to: stop or even reverse sexual development […] stop the rapid growth and bone maturation that can lead to adult short stature or an early start to periods. […] The currently approved hormone treatment is with drugs called LHRH analogs. These synthetic hormones block the body’s production of the sex hormones that cause early puberty. Positive results usually are seen within a year of starting treatment.

• #3 Precocious Puberty – Early Puberty: Symptoms & Causes

  https://my.clevelandclinic.org/health/diseases/21064-precocious-early-puberty

  Precocious puberty, or early puberty, means puberty that begins before age 8 in girls and before age 9 in boys. […] The signs and symptoms of precocious puberty in both sexes include acne, body odor and a growth spurt. Precocious puberty also causes sexual characteristics to develop early. In females, these include: Breast development, Menstruation, Pubic and underarm hair. […] Early puberty in males may cause: A deepening voice, Facial, pubic and underarm hair, Enlargement of the penis and testicles, Muscle development. […] Precocious puberty tends to affect certain groups more often. Children who are at a higher risk of developing the condition include: Females, Children with overweight or obesity, Black children. […] Early puberty may cause a growth spurt in a child, but when puberty ends, the child stops growing. Therefore, they may be shorter than other children of the same age. Precocious puberty may also be embarrassing for children who are developing more quickly than other children.

• #4 Central Precocious Puberty – familydoctor.org

  https://familydoctor.org/condition/central-precocious-puberty/

  Central precocious puberty (CPP) is the more common type. Medically, it is known as gonadotropin-dependent precocious puberty. The other type is peripheral (gonadotropin-independent) precocious puberty. A girl younger than 8 years old or a boy younger than 9 years old who has puberty symptoms may have CPP. […] The symptoms of CPP are the same as normal puberty. The difference is that they occur at a younger age. […] Common puberty symptoms for girls are: Breast development, Pubic or body hair, Growth spurt, Acne, Body odor, First menstrual cycle (period). […] Common puberty symptoms for boys are: Growth of penis and testicles, Pubic, facial, or body hair, Growth spurt, Muscle development, Acne, Body odor, Voice change (deepening). […] Treatment for CPP depends on how early it occurs. If puberty begins slightly before the normal age, your child may not need any treatment. If puberty begins much earlier, the doctor may want to stop it. This can be done with medicines, such as gonadotropin-releasing hormone agonists (GnRHa). They lower your child’s sex hormone levels to stop puberty.

• #5 Precocious Puberty: Practice Essentials, Pathophysiology, Epidemiology

  https://emedicine.medscape.com/article/924002-overview

  Precocious puberty refers to the appearance of physical and hormonal signs of pubertal development at an earlier age than is considered normal. For many years, puberty was designated as precocious in girls younger than 8 years; however, studies have come to indicate that signs of early puberty (breasts and pubic hair) are often present in girls (particularly Black girls) between ages 6-8 years. For boys, onset of puberty before age 9 years is still considered precocious. […] In central precocious puberty (CPP), which is gonadotropin-dependent, early maturation of the entire hypothalamic-pituitary-gonadal (HPG) axis occurs, with the full spectrum of physical and hormonal changes of puberty. […] Precocious puberty in girls is characterized as follows: The first and most obvious sign of early puberty is usually breast enlargement, which may initially be unilateral. Pubic and axillary hair may appear before, at about the same time as, or well after the appearance of breast tissue; axillary odor usually starts about the same time as the appearance of pubic hair. Menarche is a late event and does not usually occur until 2-3 years after onset of breast enlargement. The pubertal growth spurt occurs early in female puberty and usually is evident by the time of initial evaluation.

  Puberty is when a child’s body begins to develop and change transitioning into adulthood. […] Normally, girls start puberty between the ages of 8-13 while boys do between the ages of 9-14. Precocious puberty happens before age 8 in girls, and before age 9 in boys. […] Mostly in girls, the first sign of precocious puberty is the development of breast buds, tender lumps felt in the area under the nipples before they turn 8 years old. […] For boys, the first sign of precocious puberty is the enlargement of testicles before they turn 9 years old. […] Other changes during puberty include the following: Girls: growth spurt, vaginal discharge, pubic and armpit hair growth, body odor, menstruation. […] Boys: growth spurt, pubic and armpit hair growth, growing genitals, acne, body odor, and the crackling of the voice later on.

  Early puberty will cause a child’s body and moods to change much sooner than his or her friends and classmates. This may make a child feel self-conscious and embarrassed, or be teased by other children. […] Signs can include breast growth, pubic hair, and voice changes. […] It may be caused by tumors or growths on the ovaries, adrenal glands, pituitary gland, or brain. In many cases, no cause can be found for the disorder.

  Girls: increasing height/growth spurt, breast development, menstruation or vaginal bleeding. […] Boys: enlarging testicles and penis, pubic and underarm hair, facial hair, spontaneous erections and/or ejaculations, development of acne, deepening of the voice. […] In addition to showing physical signs of early puberty, children with precocious puberty often have low self-esteem linked to the feeling of being different than their peers. […] Early puberty will cause your child’s body to change much sooner than his peers. This sense of being different, coupled with the hormonal change-induced emotional mood swings, may make him feel self-conscious.

  Early puberty, also called precocious puberty, is when a child develops sexual characteristics at a young age. Early means these signs appear before age 8 in females and 9 in males. […] One sign of early development such as acne breakouts before age 8 for females and age 9 for males does not necessarily mean your child has early puberty. Children with early puberty have multiple signs of sexual development at a young age, which may include: Acne, Body odor, Breast development in females, Deepening of the voice in males, Growth of the testes in males, Menstruation (periods) in females, Noticeable growth in height or a growth spurt, Underarm and pubic hair growth.

• #14 Understanding early puberty: A guide for parents | UCLA Health

  https://www.uclahealth.org/news/article/understanding-early-puberty-guide-parents

  CPP is the most common type of early puberty. It occurs when the brain releases hormones called gonadotropins earlier than is developmentally typical. […] Causes of CPP include: Brain growths or tumors, Brain injury, Exposure to certain chemicals, Genetic conditions and syndromes, Family history. […] PPP occurs when the sex organs begin to mature too early. Unlike CPP, it’s not related to the brain or gonadotropin hormones. […] Causes of PPP include: Adrenal gland conditions, Genetic disorders, Hormonal medications, Tumors on the reproductive organs. […] Early puberty is rare, affecting less than 1% of U.S. children. However, research shows it is more common now than 50 years ago, particularly in girls. […] Many children who have early puberty don’t have an underlying health problem. Early puberty with no known cause is called idiopathic precocious puberty. Up to 90% of girls and 50% of boys with early puberty have the idiopathic type.

  Precocious puberty is an early onset of puberty and secondary sexual characteristics in children. […] The traditional definition of precocious puberty is the development of secondary sexual characteristics before 8 years of age in girls and 9 years in boys. […] The initial clinical signs are breast development in females and increased testicular volume (greater than 4 ml) in males. The other signs and symptoms include increased linear growth, acne, muscular changes, body odor, and pubic and axillary hair development. […] Linear growth acceleration is one of the important features of early puberty. […] The decision to treat depends on the age of the child and the progression of puberty. If the child has rapidly progressing symptoms or if bone age is significantly advanced, consider treatment.

  Abnormally early puberty is called precocious puberty and is characterized by the early development of sexual characteristics in girls before the age of 8 and in boys before the age of 9. Most children with the disorder grow fast at first, but also finish growing before reaching their full genetic height potential. […] The following are the most common symptoms of precocious puberty. However, each child may experience symptoms differently. As in typical puberty, symptoms of precocious puberty include the onset of secondary sexual characteristics, including: […] Importantly, not everyone who shows these signs has true precocious puberty. Some patients may experience only one of the symptoms of early puberty. Premature thelarche is the early development of breast tissue that does not progress to full puberty and menstruation. With premature adrenarche, the body grows underarm and pubic hair earlier than is typical. Your provider will look at the whole picture for your child and may recommend a watchful approach in these cases.

• #17 Precocious puberty – Symptoms, diagnosis and treatment | BMJ Best Practice

  https://bestpractice.bmj.com/topics/en-gb/1127

  Precocious puberty should be considered when secondary sexual characteristics appear before 8 years of age in girls and 9 years in boys. […] It results in accelerated bone development and sometimes a reduced adult height, and may have a psychosocial impact, especially due to early menses in girls. […] Two forms exist: gonadotrophin-dependent precocious puberty (known as central precocious puberty [CPP]; due to premature activation of the hypothalamo-pituitary-gonadal axis) and gonadotrophin-independent precocious puberty (GIPP; due to autonomous secretion of sex steroids). […] It also results in accelerated skeletal development with a reduced adult height. […] Treatment of CPP is usually straightforward with gonadotrophin-releasing hormone agonists. […] GIPP is more difficult to treat, and may require medications to block production or action of sex steroids. […] Treatment should be stopped once an acceptable age of puberty is reached.

  When used to determine bone age, radiography of the hand and wrist is a quick and helpful means of estimating the likelihood of precocious puberty and its speed of progression. A bone age advanced by 2 years relative to chronologic age is considered significant. […] Early onset of puberty can cause several problems. The early growth spurt initially can result in tall stature, but rapid bone maturation can cause linear growth to cease too early and may result in short adult stature. The early appearance of breasts or menses in girls and increased libido in boys can cause emotional distress for some children. […] Most girls who are aged 6-8 years at the onset of puberty achieve an adult height within the normal range or appropriate for their genetic potential. […] Most studies show significant improvement in adult height compared with height predicted at the start of therapy, but the extent of this improvement depends to some extent on the age of onset of CPP.

  Diagnosing precocious puberty involves: […] X-rays of children’s hands and wrists also are helpful in diagnosing precocious puberty. These X-rays can show if the bones are growing too quickly. […] In children with central precocious puberty, the GnRH hormone causes other hormone levels to rise. In children with peripheral precocious puberty, other hormone levels stay the same. […] Children with peripheral precocious puberty need more testing to find the cause of their condition. This might include more blood tests to check hormone levels or, in girls, an ultrasound to check for an ovarian cyst or tumor. […] Treatment for precocious puberty depends on the cause. However, when no cause can be found, treatment may not be needed, depending on the child’s age and how fast puberty is moving. Watching the child for several months might be an option.

• #24 Precocious puberty – Wikipedia

  https://en.wikipedia.org/wiki/Precocious_puberty

  Studies indicate that breast development in girls and the appearance of pubic hair in both girls and boys are starting earlier than in previous generations. […] Medical evaluation is sometimes necessary to recognize the few children with serious conditions from the majority who have entered puberty early but are still medically normal. Early sexual development warrants evaluation because it may: induce early bone maturation and reduce eventual adult height; indicate the presence of a tumour or other serious problem; cause the child, particularly a girl, to become an object of adult sexual interest. […] Overall, puberty blockers have demonstrated an excellent safety and efficacy profile in the treatment of precocious puberty. […] Early puberty is posited to put girls at higher risk of sexual abuse; however, a causal relationship is, as yet, inconclusive. Early puberty also puts girls at a higher risk for teasing or bullying, mental health disorders and short stature as adults. […] Though boys face fewer problems from early puberty than girls do, early puberty is not always positive for boys. Early sexual maturation in boys can be accompanied by increased aggressiveness due to the surge of pubertal hormones.

• #25 Precocious and Early Puberty | Resilient Sisterhood Project

  https://rsphealth.org/early-puberty/

  According to the Mayo Clinic, girls with precocious puberty tend to grow quickly at first and are often tall compared to other girls their age, but they are often shorter as adults because their bones mature faster than normal and stop growing earlier. In another interview with Dr. James-Todd about early onset puberty, she said that for each year earlier a girl starts puberty, there is about a 20% increased risk of certain diseases associated with an earlier pubertal onset. These diseases include, but are not limited to, breast and ovarian cancers, diabetes, and heart disease. […] A 2007 study led by Jane Mendel, Ph.D., et al. found that girls who experience puberty earlier can also suffer from psychological issues. The study found that they may feel anxious, self-conscious, and a sense of emotional distance from other girls their age. Girls with precocious puberty can often look three or four years older than their actual age in height and physical development, and this can create social difficulties as well because they may be seen and treated differently.

  Precocious puberty in boys is characterized as follows: The earliest evidence of puberty is testicular enlargement, a subtle finding that often goes unnoticed by patients and parents. Growth of the penis and scrotum typically occurs at least a year after testicular enlargement. Accelerated linear growth (the pubertal growth spurt) occurs later in the course of male puberty than in female puberty but often takes place by the time other physical changes are noted. […] Because of the development of more sensitive third-generation assays for luteinizing hormone (LH), which can detect levels as low as 0.1 IU/L or lower, random LH is now considered a good screening test for CPP, with levels of 0.3 IU/L or above considered diagnostic. […] Measurement of serum testosterone is useful in boys with suspected precocious puberty. Testosterone levels less than 30 ng/dL are in most cases prepubertal, while testosterone levels of 30-100 ng/dL are usually seen in cases where puberty is progressive and levels of greater than 100 ng/dL need further evaluation.

  https://www.reddit.com/r/Parenting/comments/1ff4qx0/my_son_was_diagnosed_with_central_precocious/

  My son was diagnosed with CPP at 22 months old. Likely the process started around his first birthday, although the physical symptoms did not become obvious until much later. This is a condition where the brain begins to send signals to the body that its time for puberty and hormone production begins at an inappropriately early age (girls before the age of 8, boys before 9). It is 10x more common in girls around ages 5-7, and is generally idiopathic (meaning no cause can be found), but in boys and in younger children the cause is generally a tumor in the brain or body. The treatment for CPP is hormone blockers until they reach a certain age. Without treatment, my son would achieve complete sexual maturity by the age of 4. […] Every possible cause for my son was ruled out (no tumors or abnormalities of the brain, no genetic conditions, etc) so it is idiopathic. His doctors are flabbergasted – idiopathic CPP is unheard of in a boy so young. While I am relieved that he does not have a tumor or other condition, it leaves a lot of unanswered questions.
