Primary ovarian insufficiency (POI), also called premature ovarian insufficiency and premature ovarian failure, is the partial or total loss of reproductive and hormonal function of the ovaries before age 40 because of follicular (egg producing area) dysfunction or early loss of eggs.
In 2015 a research was done on the role of autoimmunity in premature ovarian failure. [11] In 2014 there was an ovarian autoimmune disease research that revealed at least two mechanisms that protect the ovary from an autoimmune attack. [12] Research showed that Theca cells were targeting the autoimmune deficiency within the ovary.
Fragile X-associated primary ovarian insufficiency (FXPOI) is the most common genetic cause of premature ovarian failure in women with a normal karyotype 46,XX. [1] The expansion of a CGG repeat in the 5' untranslated region of the FMR1 gene from the normal range of 5-45 repeats to the premutation range of 55-199 CGGs leads to risk of FXPOI for ovary-bearing individuals.

Primary ovarian insufficiency (POI), which used to be called premature ovarian failure, is when the ovaries don’t make the typical amounts of estrogen or release eggs regularly before the age of ...
Smoking has also been found to increase follicular atresia and lead to premature ovarian failure. [27] Some of the short term effects of POF are hot flashes, irregular heart beat/heart palpitations , night sweats, urogenital symptoms, and headaches; some of the more long-term consequences of POF are osteoporosis , infertility, cardiovascular ...
Premature ovarian insufficiency (POI) is impairment of the ovaries and how they work before the age of 40 years. It can be caused by multiple factors, one being genetic. Genes and their influence determine the initial number of the primordial follicles, impact on the rate of follicular atresia, and are impactful on the age of menopause.
Premature menopause: An outdated synonym for premature ovarian failure. The term encompasses premature menopause due to any cause, including surgical removal of the ovaries for any reason. Early menopause and premature ovarian failure are no longer considered to be the same condition. [citation needed]
Primary ovarian insufficiency, also known as premature ovarian failure, can develop in women before the age of forty as a consequence of hypergonadotropic hypogonadism. [19] POI can present as amenorrhea and has similar symptoms to menopause, but measuring FSH levels is used for diagnosis. [21]
