Premature Ovarian Failure (POF)
Premature ovarian insufficiency; Primary ovarian insufficiency
Premature ovarian failure (POF), also known as premature ovarian insufficiency (POI), or primary ovarian insufficiency is the loss of function of the ovaries before age 40. A commonly cited triad for the diagnosis is amenorrhea, hypergonadotropism, and hypoestrogenism. If it has a genetic cause, it may be called gonadal dysgenesis.The cause of POF is usually idiopathic. Some cases of POF are attributed to autoimmune disorders, others to genetic disorders such as Turner syndrome and Fragile X syndrome. An Indian study showed a strong correlation between incidence of POF and certain variants in the inhibin alpha gene.
