Early and delayed puberty means that the signs of puberty appeared before or after the expected age. Normal puberty usually begins at any time between the ages of 8 and 14. Signs appearing before age 8 may indicate early puberty, while puberty not starting by age 15 may indicate delayed puberty [1]. Often this is not a cause for concern, but a medical evaluation can determine whether there is an underlying cause that needs treatment.
Many parents in Jordan notice that their child differs from classmates: a girl whose breast development starts early, or a teenager whose voice has not changed while his classmates' voices have. This guide explains what is normal, when a consultation becomes necessary, and what to expect at a pediatric or endocrinology clinic.
What Is Normal Puberty and When Does It Start in Children?
Puberty is the stage in which a boy or girl reaches sexual maturity. It usually occurs between the ages of 8 and 13 in girls, and between 9 and 14 in boys [2]. It is a gradual process controlled by hormones, and its timing varies from child to child, even within the same family.
Signs of Puberty in Girls
- The first sign is usually breast development.
- Then hair appears in the pubic area and underarms.
- Menstruation (menarche) usually comes in the later stages [2].
Signs of Puberty in Boys
- Puberty usually begins with enlargement of the testicles and penis.
- Then hair grows in the pubic area and underarms.
- As puberty progresses, muscles develop, the voice deepens, and facial hair appears [2].
Acne may appear in both sexes, and a growth spurt (rapid increase in height) usually occurs, lasting about 2 to 3 years and bringing the child close to their final adult height, which is reached after puberty ends [2]. For a detailed look at the physical and emotional changes, you can read our comprehensive guide to puberty in teenagers.
What Are Early and Delayed Puberty? What Are the Reference Ages?
Doctors rely on the age at which the first signs of puberty appear to distinguish the normal course from cases that need evaluation. According to the UK National Health Service, puberty normally begins at any time between the ages of 8 and 14 [1].
| Situation | Reference Age | What Does It Mean? |
|---|---|---|
| Puberty at the expected time | Signs begin between ages 8 and 14 | Usually a normal course |
| Possible early puberty | Signs appear before age 8 | Medical evaluation is recommended |
| Possible delayed puberty | Puberty has not started by age 15 | Medical evaluation is recommended |
The ages in the table are taken from the source [1]. Your doctor may use more precise criteria depending on the child's sex and medical history.
Early Puberty (Precocious Puberty)
This refers to the appearance of signs of puberty before age 8 [1], such as breast development, pubic hair, or testicular enlargement. Among its types covered in medical references are central precocious puberty, as well as a rare hereditary form affecting boys known as male-limited familial precocious puberty [2]. You can learn more on our page about precocious puberty, and in our answer to the question early puberty signs to watch for.
Delayed Puberty
This refers to the absence of puberty signs by age 15 [1]. Many of these teenagers start puberty later on naturally, especially if a delay runs in the family, but evaluation remains important to rule out underlying medical causes. You may also read our page on delayed puberty.
What Causes Early and Delayed Puberty?
It is not always clear what causes early or delayed puberty, and sometimes it is hereditary, recurring in the family [1]. Conditions that may be behind it include:
- Problems with the ovaries, testicles, or hormones.
- Chronic diseases such as cystic fibrosis or diabetes.
- Brain injury resulting from surgery, radiation therapy, infection, or severe head trauma.
- Malnutrition and not getting enough nutrients, which may result from conditions such as coeliac disease or eating disorders.
- Differences in sex development (DSD), which are rare conditions affecting genes, hormones, and reproductive organs [1].
Since diabetes is among the conditions listed as causes, parents may find it helpful to know the early symptoms of type 1 diabetes in children and teenagers. A child's weight and nutrition are also part of the full picture that the doctor evaluates. You can read our page on obesity in adolescents to understand how weight relates to teenage health in general.
How Are Early or Delayed Puberty Diagnosed? What Tests to Expect
The evaluation usually begins with detailed questions about when the signs appeared, the timing of puberty in the parents and siblings, and past illnesses, followed by a clinical examination that includes measuring height, weight, and stages of development. Doctors usually order tests only if they believe a medical condition may be the cause [1].
Hormone Blood Tests
Blood tests are used to measure hormone levels [1], including testosterone and estradiol or estrogen levels [2]. This helps determine whether puberty has actually started hormonally and from which source.
X-ray of the Hand and Wrist (Bone Age)
An X-ray of the wrist may be taken and used to estimate the child's expected height at adulthood [1]. The doctor compares the maturity of the bones in the image with the child's actual age, known as bone age.
Ultrasound or MRI Imaging
Ultrasound or magnetic resonance imaging (MRI) may be requested to check for problems inside the body [1], such as examining the ovaries, glands, or brain, depending on what the doctor suspects.
Growth delay is sometimes linked to other hormonal problems, so the doctor may consider possibilities such as growth hormone deficiency if a noticeably short stature accompanies the delay.
Does Every Child Need Treatment? What Are the Treatment Options?
Not every child with early or delayed puberty needs treatment. Treatment is usually required only if the condition causes physical or psychological problems [1]. In many cases the doctor simply follows up periodically, measuring height and monitoring the development of signs.
When treatment is necessary, the main options include:
- Treating the underlying condition, if one is found, such as controlling a chronic disease or addressing a nutritional or hormonal problem.
- Medications that delay puberty or stimulate its onset, depending on the type of problem [1].
These medications are hormonal and are dispensed only with a prescription. The specialist determines their type, dose, and duration according to each child's condition. In Jordan, medications and their prices are regulated by the Jordan Food and Drug Administration (JFDA). Do not start, stop, or change any hormonal treatment or dietary supplement for your child without consulting the doctor.
Important reminder: In most cases, early or delayed puberty is not a cause for alarm. The goal of the evaluation is reassurance and the early detection of any treatable cause [1].
How Do We Support the Child and Teenager Emotionally?
The emotional side can be harder for a child than the physical side. A girl whose breast development appears before her classmates may feel embarrassed or be subjected to comments, and a teenager who looks younger than his peers may feel anxious about how he appears to them. For this reason, the psychological impact is one of the factors that may warrant treatment [1].
- Talk calmly and openly in language suited to the child's age, and explain that bodies change at different speeds.
- Avoid comparisons with siblings or relatives, and avoid commenting on body shape in front of others.
- Protect their privacy, and ask their permission before discussing their condition with anyone.
- Contact the school if you notice bullying or withdrawal.
- Seek specialized psychological support if signs of persistent sadness, social withdrawal, or changes in eating and sleep appear.
It is also helpful to involve the teenager in medical visits and give them the opportunity to ask their own questions, as this builds their confidence and eases their anxiety.
When Should You See a Doctor About Early or Delayed Puberty? When Should You Go to the Emergency Room?
It is advisable to see a doctor if you think your child has early or delayed puberty. In most cases it is not a cause for concern, but tests can reveal whether there is an underlying condition [1].
See a pediatrician or endocrinologist soon if:
- Signs of puberty (breast development, pubic or underarm hair, testicular enlargement) appear before age 8.
- No sign of puberty has appeared by age 15 [1].
- Signs of puberty have accelerated noticeably or stopped after they began.
- The child is clearly shorter than peers, or has stopped growing in height.
- The child has a chronic illness, has previously undergone surgery or radiation therapy to the brain, or has suffered a severe head injury.
- Signs of malnutrition, weight loss, or an eating disorder have appeared.
Call 911 or go to the nearest emergency department if:
- The child has a sudden severe headache with repeated vomiting or vision problems.
- A seizure, loss of consciousness, or sudden change in level of consciousness occurs.
- The child has suffered a severe head injury.
- Signs of severe dehydration, rapid breathing, or extreme lethargy appear, especially with thirst and frequent urination. See what requires emergency care in diabetes in children.

- Working hours and the booking or contact methods available in the profile.
- The services listed, such as growth monitoring and hormonal disorder management.
Useful Questions to Ask at the Visit
- Is what my child is experiencing within the normal range, or do they need tests?
- What tests are required, and why? Do we need a bone age X-ray?
- Does my child need treatment now, or is monitoring enough?
- How often do we need follow-up? What signs should prompt a return before the scheduled date?
- How do I talk with my child about their condition?
Bring with you the height and weight record if available, any previous tests or scans, a list of the medications the child takes, and information about the age at which the parents went through puberty. These simple details help the doctor understand the condition considerably.
Summary for Parents
The timing of puberty varies from child to child, and the normal range is wide. However, signs appearing before age 8, or their absence by age 15, deserve medical review [1]. Early evaluation reassures the family in most cases and uncovers treatable causes in others, while emotional support and calm conversation with the child remain an essential part of care.
Frequently asked questions
What is the normal age for puberty to begin in children?
Puberty normally begins at any time between the ages of 8 and 14. It usually occurs in girls between 8 and 13, and in boys between 9 and 14. The timing varies from child to child, even among siblings, so comparison with peers alone does not indicate a problem.
When is puberty considered early?
If signs of puberty appear before age 8, such as breast development in a girl, testicular enlargement in a boy, or pubic and underarm hair, this may be early puberty. In that case, it is advisable to see a pediatrician to evaluate the situation and determine whether tests are needed.
My son is 15 and has not shown any signs of puberty. Should I worry?
Puberty not starting by age 15 may indicate delayed puberty. It is often not a cause for concern, especially if a delay runs in the family. However, it is advisable to see a doctor, because tests can help rule out causes such as hormonal problems, chronic diseases, or malnutrition.
What is a bone age test, and why does the doctor order it?
It is an X-ray of the hand and wrist in which the doctor compares the maturity of the bones with the child's actual age. This image helps estimate the child's expected adult height and gives an idea of whether growth is advanced or delayed. It is a simple and quick test.
Does every child with early or delayed puberty need hormonal treatment?
No. Treatment is usually required only if the condition causes physical or psychological problems. In many cases follow-up is enough. When treatment is needed, the doctor may treat the underlying cause or prescribe medications that delay or stimulate puberty. Hormonal treatment must never be started without a prescription.
Should I see a pediatrician or an endocrinologist directly?
You can start with a pediatrician, who evaluates the case and refers the child to a pediatric endocrinologist if necessary. You can also see an endocrinologist directly when the problem is clear. Search by specialty and governorate, and check the clinic's location, working hours, and contact method.
