Amenorrhoea is nearly always endocrine in origin, and associated with anovulation and infertility.
Common causes include polycystic ovary syndrome, hypothalamic amenorrhoea, ovarian failure and hyperprolactinaemia (1). Anatomical defects account for about 1% of cases. Some of these patients may be ovulating normally, but the bleeding is concealed.
