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.
Generally, diseases outlined within the ICD-10 codes N70-N98 within Chapter XIV: Diseases of the genitourinary system should be included in this category. Wikimedia Commons has media related to Diseases and disorders of the female reproductive system .
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.
Treatment varies based on the 4 most common causes of anovulation: polycystic ovarian syndrome (PCOS), hypogonadotropic hypogonadism (HA), primary ovarian insufficiency (POI), and hyperprolactinemia. [10] Importantly, semen analysis should be carried out of the XY partner to exclude severe XY factors before managing anovulatory subfertility. [10]
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 ...
In some cases (more so in younger women) ovarian function and ovulation can spontaneously resume. With POF up to 50% of women may ovulate once in any given year and 5–10% may become pregnant. POF is often associated with autoimmune diseases. [citation needed] Premature menopause: An outdated synonym for premature ovarian failure. The term ...
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]
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.
