[…] Puberty is the natural physical and hormonal changes that occur as children transition into adulthood. It typically begins between eight and 13 in girls and between nine and 14 in boys, although individual timelines vary. […] Precocious puberty occurs when puberty begins earlier than usual. In girls, this means before age eight, and in boys, before age nine. […] Delayed puberty is when the onset of puberty occurs later than the typical age range. In girls, this means no signs of puberty by age 13, and in boys, no signs by age 14.

  Boys will typically go through puberty as they grow and develop into young adults. Sometimes boys go through puberty later than we expect. Learn about the causes and symptoms of delayed puberty in boys. […] Delayed puberty is when your son does not show the first signs of puberty by the time he is 14 years old. […] Boys usually start to go through puberty between the ages of 9-14 years. When your son starts to go through puberty, his gonads (testes) and adrenal glands (glands that sit on top of the kidneys) release hormones. These hormones cause the first signs of puberty, which are an increase in the size of the testes and length of the penis, body odor, underarm hair, pubic hair and acne (pimples). Over time, boys will develop later signs of puberty, such as increased muscle mass, stronger bones, a deeper voice and a growth spurt.

  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. […] The first and most obvious sign of early puberty is usually breast enlargement, which may initially be unilateral.

[…] Early puberty can be categorised into Central Precocious Puberty (CPP) and Peripheral Precocious Puberty (PPP). […] Children with early puberty mature and stop growing at an earlier age compared to their peers and can be shorter than expected as adults. […] Delayed puberty is more common in boys than girls. […] Puberty can be delayed for several reasons. Most often, it is simply because your child is a late bloomer and it usually does not require any kind of treatment. […] Early puberty is defined as the appearance of any sign of secondary sexual characteristics in boys younger than 9 years and in girls younger than 8 years of age. Delayed puberty is defined by the absence of testicular enlargement in boys by age of 14 years or breast development in girls by age of 13 years.

  Estrogen or testosterone being made too soon causes this type of precocious puberty. […] With this type of precocious puberty, the hormone in the brain (GnRH) that typically causes puberty to start isn’t involved. Instead, the cause is the release of estrogen or testosterone into the body. A problem with the ovaries, testicles, adrenal glands or pituitary gland causes the hormone release. […] Possible complications of precocious puberty include: Short height. Children with precocious puberty might grow quickly at first and be taller than others their ages. But their bones mature too soon. So these children often stop growing earlier than usual. This can cause them to be shorter than average as adults. Social and emotional problems. Children who begin puberty long before others of their age might be upset about the changes in their bodies. For example, dealing with early periods can cause distress.

  Puberty is the process in which children’s bodies change into adult bodies and become capable of reproduction. In girls, the onset of puberty usually happens between the ages of 8 and 13, and in boys, between the ages of 9 and 14. […] Sometimes, puberty starts early (precocious puberty). Other times, it starts late (delayed puberty). Early or late starts do not always require treatment. In some cases, we may use medicines to help control this timing and put kids on track with their peers. […] Puberty timing is also important because it affects a child’s growth. This is because puberty hormones spark a growth spurt, which at first, causes the bones to grow. Then, the growth plates close. […] When children have a puberty growth spurt too early, their growth plates may also close too early. This means children with early puberty seem tall at first, but then stop growing sooner than their friends, and they end up shorter than expected. Treatment can prevent this early growth and early end to growth.

  Puberty is considered delayed when the child has not begun puberty when two standard deviations or about 95% of children from similar backgrounds have. In North American girls, puberty is considered delayed when breast development has not begun by age 13, when they have not started menstruating by age 15, and when there is no increased growth rate. Furthermore, slowed progression through the Tanner scale or lack of menarche within 3 years of breast development may also be considered delayed puberty. […] In North American boys, puberty is considered delayed when the testes remain less than 2.5 cm in diameter or less than 4 mL in volume by the age of 14. Delayed puberty is more common in males. […] Although the absence of pubic and/or axillary hair is common in children with delayed puberty, the presence of sexual hair is due to adrenal sex hormone secretion unrelated to the sex hormones produced by the ovaries or testes.

  While delayed puberty is actually defined by signs (lack of increase in testicle size by age 14 or lack of breast development by age 13), we often see children who come in for an evaluation because they’re concerned that they’re not growing as quickly as their peers. Your child could have pubic hair and body odor but still meet the definition for delayed puberty, so she should be evaluated. This is because while they tend to happen around the same time, development of breasts and development of pubic hair/body odor are two separate processes, each triggered by their own hormones. The diagnosis of delayed puberty only takes into account the process and the hormones that lead to breast development. […] A few different things can cause delayed puberty. Constitutional growth delay (CGD) is a temporary delay in skeletal growth, which keeps a child from being as tall as his peers, at least for a while. Among boys, around 60 percent of the time, delayed puberty is caused by constitutional growth delay. It’s hard to say for sure, but CGD is thought to affect around twice as many boys as girls. CGD is a normal variant of growth, but may still make a child feel distressed. Kids with CGD go through puberty and reach an appropriate adult height, just not as quickly as their peers do.

[…] The hypothalamic-pituitary-gonadal axis can also be affected at the level of the brain. The brain does not send its hormonal signals to the gonads (low gonadotropins), causing the gonads to never be activated in the first place, resulting in hypogonadotropic hypogonadism.

It is the most common cause of delayed puberty in girls and even more so in boys. It is commonly inherited, with as much as 80% of the variation in the age of onset of puberty due to genetic factors. […] When underweight or sickly children are present with pubertal delay, it is warranted to search for illnesses that cause a temporary and reversible delay in puberty. Chronic conditions such as sickle cell disease and thalassemia, cystic fibrosis, HIV/AIDS, hypothyroidism, chronic kidney disease, and chronic gastroenteric disorders cause a delayed activation of the hypothalamic region of the brain to send signals to start puberty.
