Delayed Puberty in Children
Delayed Puberty in Children: Causes, Symptoms, Diagnosis, and Treatment
Is your child entering puberty later than their peers? Delayed puberty can be a normal variation, especially in children who are “late bloomers,” but it can sometimes be linked to hormonal, growth, genetic, nutritional, or chronic medical conditions.
At HGH for Children, we help families understand delayed puberty by considering growth patterns, Bone Age, hormone levels, and pubertal development to determine whether further evaluation may be appropriate.
When Should Parents Seek an Evaluation?
A growth and puberty assessment may be appropriate when:
- A boy has no testicular enlargement by age 14.
- A girl has no breast development by age 13 or no menstrual period by age 15.
- Growth velocity is unusually low.
- Height percentiles are declining.
- Bone Age is delayed.
- Pubertal development has stalled.
- There are symptoms of hormonal imbalance or chronic illness.
- The child is experiencing significant emotional distress.
Regular monitoring helps track the child’s growth progress, assess changes in pubertal development, and ensure that physical growth and hormonal changes are progressing as expected over time.
Why Families Choose HGH for Children.com
At HGHforChildren.com, growth concerns are evaluated in the context of the child’s developmental pattern, including Delayed Puberty, Constitutional Growth Delay, Delayed Bone Age, Growth Hormone Deficiency, Low IGF-1, Poor Growth Velocity, Idiopathic Short Stature, and Pituitary Disorders.
The goal is to help families understand why development may be delayed and determine whether testing, monitoring, or treatment should be considered.
How Is Delayed Puberty Diagnosed?
A comprehensive evaluation considers pubertal development and the child’s growth pattern.
Step 01
Medical History
The clinician may review family history of puberty timing, growth patterns, medical conditions, nutrition, athletic activity, medications, and chronic illness.
Step 02
Physical Examination
The evaluation may include height, weight, growth velocity, growth chart percentiles, pubertal development, and Tanner staging.
Step 03
Bone Age X-Ray
A Bone Age X-ray helps assess delayed puberty. Bone age is often younger in children with Constitutional Delay of Growth and Puberty, but it cannot predict final adult height exactly.
Step 04
Laboratory Testing
Testing may include IGF-1, IGFBP-3, testosterone or estradiol, LH, FSH, thyroid studies, CBC, and a comprehensive metabolic panel to assess growth, hormones, and pubertal development.
Step 05
Advanced Testing
Some children may require Growth Hormone Stimulation Testing, pituitary MRI, or genetic testing. Testing depends on the child's individual findings.
Does Delayed Puberty Affect Height?
Delayed puberty can temporarily make a child appear shorter or less physically developed than classmates. The pubertal growth spurt contributes substantially to adolescent height gain, so when puberty begins later, the associated growth acceleration may also occur later.
Children with Constitutional Delay of Growth and Puberty may continue growing after many peers have completed their growth. However, delayed puberty does not guarantee a specific adult height.
Hormonal disorders, chronic illnesses, and other medical conditions can affect growth potential if untreated. Appropriate evaluation can help determine whether delayed development represents normal variation or an underlying condition.
Signs and Symptoms of Delayed Puberty
Boys
Common signs include no testicular enlargement by age 14, limited facial or body hair, a high-pitched voice, limited muscle development, delayed growth spurt, and shorter stature compared with classmates.
Girls
Possible signs include no breast development by age 13, delayed menstrual periods, slower growth progression, and minimal pubertal development.
What Is Delayed Puberty?
Delayed puberty occurs when physical signs of sexual development begin later than expected or do not progress normally.
In Boys
Puberty is generally considered delayed when testicular enlargement has not begun by age 14 or when pubertal development starts but does not progress appropriately.
In Girls
Evaluation is generally appropriate when breast development has not started by age 13, when menstruation has not occurred by age 15, or when pubertal development significantly slows or stops.
These guidelines help identify children who may benefit from evaluation; they do not automatically indicate a medical disorder.
What Happens During Puberty?
Puberty begins when the brain activates the hypothalamic-pituitary-gonadal (HPG) axis. This hormonal pathway stimulates reproductive development, secondary sexual characteristics, and the adolescent growth spurt.
In Boys
Puberty may include testicular enlargement, penis growth, voice deepening, facial and body hair, increased muscle mass, and a growth spurt.
In Girls
Puberty may include breast development, body hair growth, menstruation, body composition changes, and increased height velocity. When puberty begins later, physical maturation and the associated growth spurt may also occur later.
What Causes Delayed Puberty?
Delayed puberty has several possible causes. Evaluating growth, family history, pubertal development, and overall health helps determine which pattern may apply.
Constitutional Delay of Growth and Puberty
Constitutional Delay of Growth and Puberty (CDGP) is a common explanation for delayed puberty. These children are often described as “late bloomers.” They may have delayed Bone Age, a later growth spurt, later pubertal development, and a family history of delayed puberty.
Many eventually progress through puberty naturally.

Growth Hormone Deficiency
Growth Hormone Deficiency (GHD) can contribute to poor growth, short stature, delayed Bone Age, and delayed pubertal development. Children with GHD may have reduced growth velocity and other findings that distinguish their pattern from constitutional delay.
Hypogonadism
Hypogonadism occurs when the body does not produce sufficient sex hormones or when the normal hormonal pathway controlling puberty is impaired. In boys, low testosterone may be associated with testicular dysfunction or disorders affecting the hypothalamus or pituitary gland. In girls, low estrogen production may be related to ovarian, hypothalamic, pituitary, or genetic conditions.
Chronic Medical Conditions, Nutrition, and Thyroid Disorders
Celiac disease, inflammatory bowel disease, chronic kidney disease, autoimmune disorders, inadequate nutrition, and eating disorders can interfere with pubertal development.
Hypothyroidism
Hypothyroidism can cause slow growth, delayed puberty, delayed bone age, fatigue, and weight changes due to low thyroid hormone levels.
Genetic Conditions
Klinefelter Syndrome in boys and Turner Syndrome in girls can affect pubertal development. Genetic testing may be considered when clinical findings suggest a genetic cause.
Growth Hormone Therapy
Growth hormone therapy may be appropriate when Growth Hormone Deficiency is confirmed or when another recognized indication for treatment is present. HGH is not automatically indicated simply because a child has delayed puberty or delayed Bone Age.
Observation
Children with constitutional delay may need regular monitoring, growth tracking, pubertal assessments, and periodic reassessment. Many eventually enter puberty naturally without medical intervention.
Can Delayed Puberty Be Treated?
Treatment depends on the underlying cause.
Hormonal Therapy
For selected children and adolescents, a pediatric endocrinologist may consider hormonal treatment.
In boys, a short course of testosterone therapy may sometimes be used to initiate pubertal development. In girls, estrogen therapy may be considered when clinically indicated.
Treatment depends on diagnosis, age, pubertal stage, laboratory findings, Bone Age, and overall health.
Insights From Dr. Devin Stone, ND

Not every short child has a deficiency. The key is identifying abnormal growth velocity—not just height.

Frequently Asked Questions
Is delayed puberty always a medical problem?
No. Constitutional Delay of Growth and Puberty is a common cause, and many children eventually progress through puberty normally.
Can delayed puberty affect my child's height?
It can affect the timing of the growth spurt. Some late-maturing children continue growing later than their peers, but final height depends on multiple factors.
Does delayed puberty mean my child has Growth Hormone Deficiency?
No. Growth Hormone Deficiency is one possible cause of poor growth but is different from constitutional delay. Evaluation can help distinguish between these conditions.
Can delayed puberty be treated?
Treatment depends on the cause. Some children need only monitoring, while selected children may benefit from hormonal therapy or treatment of an underlying medical condition.
Schedule a Growth Consultation
If your child’s puberty appears significantly later than expected, an evaluation can help clarify whether they are simply a late bloomer or whether an underlying condition needs attention.
HGHforChildren.com can help families review growth patterns, pubertal development, Bone Age, and relevant laboratory findings to determine appropriate next steps.
A consultation does not automatically mean treatment is necessary.
