An immunological insight into premature ovarian failure (POF).
Premature ovarian failure (POF), a serious life-changing condition that affects young women, remains an enigma and the researchers' challenge. The term POF generally describes a syndrome of gonadal failure before the age of 40, characterized by amenorrhea, sex steroid deficiency and elevated levels of gonadotropins. Infertility and psychological stress are common consequences of this entity the prevalence of which is 0.9-3%. The known cause of this condition includes: genetic aberrations, autoimmune ovarian damage, iatrogenic and environmental factors, although in majority of cases the underlying cause is not identified. For many women in whom the cause of ovarian failure is unknown, autoimmunity may be the pathogenic mechanism. There is currently evidence that some cases of POF are due to faulty recognition of self in the ovary by the immune system, possibly provoked by genetic or environmental factors initiating such immune response. Numerous evidence, including association with multiple autoimmune endocrine disorders, clinical reversibility, transitory estrogen deficiency, histological and immunological features and the demonstration of circulating ovarian antibodies in serum samples from women with POF, have suggested its immunological origin. We discuss the possible role of such an autoimmune process as a cause or consequence of POF including treatment strategies in POF patients.
