Outflow Tract - Imperforate hymen, Vaginal atresia, Cervical stenosis, Müllerian agenesis (MRKH syndrome) 2. Uterine - Congenital absent uterus, Asherman syndrome 3. Ovarian (↑FSH) - Turner syndrome (45,XO), Gonadal dysgenesis, POI, 17-hydroxylase deficiency 4. Hypothalamic/Pituitary (↓FSH/LH) - Kallmann syndrome (anosmia), Hypopituitarism, Nutritional/exercise, Constitutional delay SECONDARY AMENORRHEA (5 categories): 1.
