Puberty is said to be delayed when symptoms do not appear by age 13 for girls and age 14 for boys. Delayed puberty can be hereditary; the late onset of puberty may run in families. However, delayed puberty may also be due to chromosomal abnormalities, genetic disorders, chronic illnesses, or tumors that damage the pituitary gland or the hypothalamus, which affect maturation.
A noted lack of symptoms of puberty is the primary indicator that a child may be experiencing delayed puberty. The following are the most common symptoms of delayed puberty. However, each child may experience symptoms differently. Symptoms may include:
lack of breast development by age 13
more than five years between breast growth and menstrual period
lack of pubic hair by age 14
failure to menstruate by age 16
lack of testicular enlargement by age 14
lack of pubic hair by age 15
more than five years to complete genital enlargement
The symptoms of delayed puberty may resemble other problems or medical conditions. Always consult your child's physician for a diagnosis.
In addition to a complete medical history and physical examination, diagnosis of delayed puberty may include:
blood tests (to check for chromosomal abnormalities, measure hormone levels, and test for diabetes, anemia, and other conditions that may delay puberty)
x-ray - a diagnostic test which uses invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs onto film. A bone x-ray of the hand or wrist may be performed to determine bone maturity.
computed tomography scan (Also called a CT or CAT scan.) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.
magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body.
Specific treatment for delayed puberty will be determined by your child's physician based on:
your child's age, overall health, and medical history
extent of the condition
your child's tolerance for specific medications, procedures, or therapies
expectations for the course of the condition
your opinion or preference
Treatment for delayed puberty depends on the cause of the problem. Often, when the underlying cause is treated, puberty proceeds normally. If the delayed puberty is due to heredity, no treatment is usually necessary. In some cases, treatment may involve hormone therapy to stimulate the development of secondary sexual characteristics, or surgery to correct an anatomical problem.
