Delayed Puberty in Children: Causes, Symptoms, Diagnosis, and Treatment

Medically Reviewed by Dr Devin Stone ND Updated: 05/30/2026

Is your child entering puberty later than their peers?
Delayed puberty is a common reason families seek evaluation from a pediatric growth specialist. While many children who develop later than average are simply "late bloomers," delayed puberty can sometimes signal an underlying hormonal, growth, genetic, or medical condition that requires further evaluation.

Puberty plays a critical role in physical development, emotional health, bone growth, and final adult height. Understanding why puberty is delayed can help families make informed decisions and ensure children receive appropriate care when needed.

At HGHforChildren.com, we help families identify whether delayed puberty is part of a normal developmental pattern or a sign of an underlying growth disorder.

What Is Delayed Puberty?

Delayed puberty occurs when physical signs of sexual development begin later than expected.

Boys

Puberty is generally considered delayed if:

  • Testicular enlargement has not begun by age 14
  • There is little or no pubertal progression after puberty starts

Girls

Puberty is generally considered delayed if:

  • Breast development has not started by age 13
  • Menstruation has not occurred by age 15
  • Pubertal development has significantly slowed or stalled

Although these age ranges serve as general guidelines, every child develops at a different pace.

What Happens During Puberty?

Puberty begins when the brain activates the hypothalamic-pituitary-gonadal (HPG) axis.

This process triggers the release of hormones that stimulate growth and sexual development.

In Boys

Puberty causes:

  • Testicular enlargement
  • Growth of the penis
  • Voice deepening
  • Facial and body hair growth
  • Increased muscle mass
  • Growth spurts

In Girls

Puberty causes:

  • Breast development
  • Menstruation
  • Wider hips
  • Body hair growth
  • Increased height velocity
  • Changes in body composition

When this hormonal process is delayed, physical development occurs later than expected.

Signs and Symptoms of Delayed Puberty

Boys

Common signs include:

  • No testicular enlargement by age 14
  • Minimal facial hair
  • High-pitched voice
  • Limited muscle development
  • Delayed growth spurt
  • Shortest in class

Girls

Common signs include:

  • No breast development by age 13
  • Delayed menstrual periods
  • Slower growth progression
  • Minimal pubertal development

Emotional Symptoms

Many children experience:

  • Low self-confidence
  • Social anxiety
  • Embarrassment
  • Poor body image
  • Increased stress around peers

The emotional impact of delayed puberty can be significant, particularly during middle school and high school years.

What Causes Delayed Puberty?

Several conditions can delay the normal onset of puberty.

Constitutional Delay of Growth and Puberty (CDGP)

The most common cause of delayed puberty is Constitutional Delay of Growth and Puberty (CDGP).

These children are often referred to as:

  • Late bloomers
  • Late developers

Characteristics include:

  • Delayed bone age
  • Delayed growth spurt
  • Family history of delayed puberty
  • Normal eventual adult height

Many parents report:

"I didn't hit puberty until high school."

Constitutional delay often runs in families.

Growth Hormone Deficiency

Children with growth hormone deficiency may experience:

  • Poor growth velocity
  • Delayed bone age
  • Delayed pubertal development
  • Short stature

Growth hormone plays an important role in normal growth and maturation.

Hypogonadism

Hypogonadism occurs when the body produces insufficient sex hormones.

Boys

Low testosterone production may result from:

  • Pituitary disorders
  • Hypothalamic disorders
  • Testicular dysfunction

Girls

Low estrogen production may result from:

  • Ovarian dysfunction
  • Pituitary abnormalities
  • Genetic disorders

Chronic Medical Conditions

Puberty can be delayed by:

  • Celiac disease
  • Inflammatory bowel disease
  • Chronic kidney disease
  • Autoimmune disorders
  • Poor nutrition
  • Eating disorders

The body may delay reproductive development when energy reserves are inadequate.

Thyroid Disorders

Hypothyroidism can contribute to:

  • Slowed growth
  • Delayed puberty
  • Delayed bone age
  • Fatigue
  • Weight gain

Thyroid testing is a routine part of delayed puberty evaluations.

Genetic Conditions

Certain genetic syndromes can affect puberty.

Examples include:

Boys

  • Klinefelter Syndrome

Girls

  • Turner Syndrome

Genetic testing may be recommended in select cases.

How Is Delayed Puberty Diagnosed?

A comprehensive growth and hormone evaluation typically includes:

Medical History

Your provider may review:

  • Family history of puberty timing
  • Growth patterns
  • Medical history
  • Nutrition
  • Athletic activity
  • Chronic illnesses

Physical Examination

The physician evaluates:

Bone Age X-Ray

Bone age assessment is one of the most important tests.

Children with constitutional delay frequently have:

  • Bone age younger than chronological age
  • Additional growth potential remaining

A delayed bone age often supports a diagnosis of constitutional growth delay.

Laboratory Testing

Common laboratory studies include:

  • IGF-1
  • IGFBP-3
  • Testosterone (boys)
  • Estradiol (girls)
  • LH
  • FSH
  • Thyroid panel
  • CBC
  • Comprehensive metabolic panel

These tests help determine whether puberty hormones are appropriately developing.

Advanced Testing

Some children may require:

  • Growth hormone stimulation testing
  • Pituitary MRI
  • Genetic testing

depending on clinical findings.

Does Delayed Puberty Affect Height?

Yes.

Puberty is responsible for the largest growth spurt of childhood.

If puberty begins late:

  • Growth may temporarily lag behind peers
  • Children often appear younger than classmates
  • Final adult height may still be normal if growth plates remain open

However, certain hormonal disorders can reduce adult height potential if left untreated.

This is why evaluation is important when puberty is significantly delayed.

Can Delayed Puberty Be Treated?

Treatment depends entirely on the cause.

Observation

Children with constitutional delay often require only:

  • Monitoring
  • Growth tracking
  • Repeat evaluations

Many eventually progress through puberty naturally.

Hormonal Therapy

In selected cases, pediatric endocrinologists may recommend:

Boys

  • Short-term testosterone therapy

Girls

  • Estrogen therapy when indicated

These therapies may help initiate pubertal development while further evaluation continues.

Growth Hormone Therapy

Growth hormone therapy may be appropriate when:

  • Growth hormone deficiency is confirmed
  • Other qualifying growth disorders are present

Treatment decisions should always be individualized and supervised by a qualified specialist.

When Should Parents Seek Evaluation?

A growth and puberty assessment may be appropriate if:

Boys

Girls

  • No breast development by age 13
  • No menstrual period by age 15

Both

  • Delayed bone age
  • Falling off growth curves
  • Family concern about development
  • Signs of hormonal imbalance

Early evaluation can help identify treatable causes and provide reassurance when development is simply delayed.

Frequently Asked Questions

Is delayed puberty common?

Yes. Constitutional Delay of Growth and Puberty is one of the most common causes of delayed puberty.

Is delayed puberty genetic?

Often. Many children with delayed puberty have parents or siblings who also developed later than average.

Can delayed puberty affect adult height?

It can. Some children continue growing longer and ultimately reach normal adult height, while others may have underlying conditions that affect growth potential.

Can a child have delayed puberty and growth hormone deficiency?

Yes. Growth hormone deficiency can contribute to both delayed growth and delayed puberty.

Will my child eventually catch up?

Many children with constitutional delay eventually experience a normal pubertal progression and achieve a height consistent with their genetic potential.
