Delayed puberty in girls
Delayed puberty is defined as absence of the start of sexual maturation at the expected time. Sometimes, delayed puberty is caused by chronic medical problems, hormonal disorders, radiation therapy or chemotherapy, disordered eating or excessive exercise, genetic disorders, tumors, and certain infections. Typical symptoms include a lack of testicular enlargement in boys and a lack of breasts and menstrual periods in girls. The diagnosis is based on the results of a physical examination, various laboratory tests, a bone age x-ray, and, if needed, genetic testing and magnetic resonance imaging.
