Overview
The hallmark of delayed puberty is lack of testicular enlargement in boys or breast development in girls at a specific age. Secondary sexual characteristics are checked in 2-2.5 standard deviation more than the average age of puberty onset in standard population, 14years for boys and 13years for girls. A positive family history of delayed puberty is frequently seen in delayed puberty. The most common symptom of delayed puberty is anosmia or hyposmia. Symptoms of underlying comorbidities are less common symptoms in delayed puberty.
History and Symptoms
- The hallmark of delayed puberty is lack of testicular enlargement in boys or breast development in girls at a specific age. Secondary sexual characteristics are checked in 2-2.5 standard deviation more than the average age of puberty onset in standard population, 14years for boys and 13years for girls. A positive family history of delayed puberty is frequently seen in delayed puberty. The most common symptom of delayed puberty is anosmia or hyposmia. [1]

Patients with delayed puberty may have a positive history of one or more of the following:[1]
- Delayed puberty in family

- Sickle cell disease
- Thalassemia
- Obesity

Common Symptoms
Common symptoms of delayed puberty are:
- Lack of testicular enlargement
- Testes volume less than 3 mL.
- Testicular size is determined by measuring its volume using Prader orchidometer or measuring its longest axis length.
- The volume of 4 mL or longest axis of 2.5 cm demonstrates the onset of puberty.[5]
- Lack of breast development
- Lack of pubic and axillary hair
- Pubic and axillary hair, body odor, and also acne are results of adrenal androgens.
- Axillary hairs are grown in the middle of puberty.
- Lack of menarche
- Lack of growth spurt
- By the time of puberty onset, there is a surge in growth hormone (GH) secretion. Sex steroids also have some roles in increasing the growth rate in puberty.[7]
- Growth rate is increased during puberty; because the estrogen, either from the ovary or from aromatization of testosterone, increases the GH response in the body.[8]
- Growth spurt occurred in the middle to late stages of puberty.
- Most of the times, it occurs by the time of thelarche stage 3.
- It is consist of 25 cm growth in girls and 30 cm growth in boys, on average.
- Anosmia/Hyposmia
- Kallmann syndrome is associated with lack of neural tissue migration to olfactory bulbs in central nervous system (CNS).
- Kallmann syndrome is a cause of hypogonadotropic hypogonadism.[9]
Less Common Symptoms
Less common symptoms of delayed puberty are the symptoms related to its underlying diseases, include:
- Turner's syndrome
- Short stature
- Webbed neck
- Low posterior hairline
- Prominent posterior rotated ears[10]
- Klinefelter syndrome
- Tall stature
- Greater lower limbs proportion
- Atrophic testis
- Developmental delay
- Gynecomastia[11]
- Prader-Willi syndrome
- CHARGE syndrome
- Coloboma
- Heart defects (especially, tetralogy of Fallot)
- Atresia of the choanae
- Retardation of growth and development
- Genital underdevelopment
- Ear abnormalities[13]
- Septo-optic dysplasia[14]
- Visual impairment
- Nystagmus
- Recurrent seizures (epilepsy)
- Abnormal movements
