Secondary amenorrhoea due to autoimmune ovarian failure.

A case of spontaneous premature menopause due to autoimmune ovarian failure is described. This report emphasises that this uncommon condition is important to diagnose because of its association with other autoimmune endocrine disorders including Addison's disease. In addition, in the present case, the marked increase in luteinizing hormone with relatively normal follicle stimulating hormone raises the possibility of a non-steroidal inhibitory feedback of follicle stimulating hormone.
