Dear chirag ,this consition is known as primary amenorrhoea.
These are the causes of amenorrhoea
Generalized pubertal delay
Constitutional delay
Hypergonadotropic hypogonadism
Turner syndrome
Gonadal dysgenesis with mosaic karyotype
Pure gonadal dysgenesis (Perrault syndrome, Swyer syndrome)
Gonadotropin-resistant ovary syndrome
Acquired causes (eg, high-dose alkylating chemotherapy, pelvic radiation, autoimmune oophoritis)
Hypogonadotropic hypogonadism
Chronic conditions (eg, starvation, excessive exercise, depression, psychological stress, marijuana use, Crohn disease, cystic fibrosis, sickle cell disease, thalassemia major, human immunodeficiency virus [HIV] infection, renal disease, thyroid disease, diabetes mellitus, anorexia nervosa)
Slow-growing CNS tumors (eg, adenomas, craniopharyngiomas, meningiomas, pituitary microadenomas)
Abnormal hypothalamic development (eg, Kallmann syndrome, Prader-Willi syndrome, and Laurence-Moon-Biedl syndrome)
Acquired miscellaneous disorders (eg, infiltration disorders [sarcoidosis, Langerhans cell histiocytosis, syphilis, tuberculomas], ischemia disorders [caused by trauma, aneurysm, obstruction of the aqueduct of Sylvius] and destruction [concentrated, high-dose exposure to radiation])
Normal puberty with estrogen expressed: Associated with hyperandrogenicity (eg, PCO syndrome, late-onset 21-hydroxylase deficiency [nonclassic congenital adrenal hyperplasia], immaturity of the hypothalamic-pituitary-ovarian axis, Cushing disease, androgen-producing ovarian or adrenal tumors, ovarian stromal hypertrophy)
Normal puberty with prior estrogen expression but no current estrogen expression
Hypergonadotropic hypogonadism (eg, premature ovarian failure, high-dose alkylating chemotherapy or pelvic radiation occurring after puberty, autoimmune oophoritis)
Hypogonadotropic hypogonadism
Chronic conditions that occur after puberty (eg, starvation, excessive exercise, depression, psychological stress, marijuana use, Crohn disease, cystic fibrosis, sickle cell disease, thalassemia major, HIV infection, renal disease, thyroid disease, diabetes mellitus, anorexia nervosa)
Slow-growing CNS tumors (eg, adenomas, craniopharyngiomas, meningiomas, pituitary microadenomas)
Acquired miscellaneous disorders (eg, infiltration disorders [sarcoidosis, Langerhans cell histiocytosis, syphilis, tuberculomas], ischemia disorders [caused by trauma, aneurysm] and destruction [concentrated, high-dose exposure to radiation])
Anomalies of the genital tract
Müllerian agenesis (eg, Mayer-Rokitansky-Kuster-Hauser syndrome5) breast present with rudimentary or absent uterus
Congenital or acquired anatomic obstruction (eg, imperforate hymen, transverse vaginal septum, Asherman syndrome, endometrial destruction due to severe infection or surgery)
Androgen insensitive syndrome (absent uterus with normal breast development)
