This is sign of delayed puberty.You should get it investigated through following tests:
Investigations for chronic disease: FBC, ferritin, renal function tests and electrolytes, coeliac screening, urinalysis for blood and protein, etc.Investigations related to disorders of gonadal axis:Chromosomes (eg for Turner's syndrome and Klinefelter's syndrome).Basal FSH and LH and serum estradiol/testosterone.Pelvic ultrasound in girls.Bone age: a delayed bone age may occur in CDGP, growth hormone deficiency and hypothyroidism.GnRH test and tests for prolactin and growth hormone (see separate article Pituitary Function Tests); some cases of central delay are difficult to assess and the GnRH test cannot distinguish between physiological delay and gonadotrophin deficiency.MRI or CT scan of the pituitary and surrounding structures may be indicated.
It can be due to hormonal or genetic factors for which you should be examined and investigated through above tests.
Okay Thanks Doc...
