The role of autoimmunity in premature ovarian failure

چکیده
Premature ovarian failure (POF) is a heterogeneous syndrome with several causative factors. Autoimmune mechanisms are involved in pathogenesis of 4-30 % of POF cases. The present review focuses on the role of autoimmunity in the pathophysiology of POF. The evidences for an autoimmune etiology are: demonstration of ovarian autoantibodies, the presence of lymphocytic oophoritis, and association with other autoimmune disorders. Several ovarian antigenic targets have been identified in POF patients. The oocyte seems to be the most often targeted cell. Lymphocytic oophoritis is widely present in POF associated adrenal insufficiency. Addison's disease is one of the most common autoimmune disorders associated with POF. Early detection of this potentially life threatening disease was recommended in several studies. The gold standard for detecting autoimmune POF is ovarian biopsy. This procedure is not recommended due to unknown clinical value, expense, and risks. Several immunoassays have been proposed as substitute diagnostic tools. Nevertheless, there is no clinically proven sensitive and specific serum test to confirm the diagnosis of autoimmune POF or to anticipate the patient's chance of developing POF or associated diseases. Some authors suggested the possible effects of immuno-modulating therapy on the resumption of ovarian function and fertility in a selected group of autoimmune POF patients. However, in most instances, this treatment fails to reverse the course of the disease. Numerous studies illustrated that standard treatment outcome for infertility is less effective in the presence of ovarian autoimmunity. The antibody-induced damage could be a pathogenic factor. Nevertheless, the precise cause remains obscure.

The Presence of Anti Thyroid and Anti Ovarian Auto-Antibodies in Familial Premature Ovarian Failure
Background Premature ovarian failure (POF) is a disorder of multi causal etiology. Autoimmunity has been proposed as a mechanism for some cases of ovarian follicle dysfunction which is evident in POF. The aim of this study was to identify the level of auto-antibodies in POF and familial POF patients. MaterialsAndMethods In this study, auto-antibodies including anti-ovarian antibody (AOA), anti ...

Primary ovarian insufficiency (POI), commonly referred to premature ovarian failure, is defined as ovarian failure before the age of 40 years. It is the loss of ovarian function caused by a process directly affecting ovaries. Cancer therapy which includes surgery, radiotherapy, and chemotherapy influence ovarian function, leading to premature menopause and loss of fertility. POI is idiopathic i...

Background: Premature ovarian failure (POF) is defined by the association of amenorrhea, hypoestrogenism and elevated (menopausal) levels of serum gonadotropins before age of 40 years-old. This condition affects approximately %1 of women under 40 years of age. Physiologic replacement of ovarian steroid hormones seems rational until the age of normal menopause. Temporary return of ovarian functi...

Background: Immaturity of the ovarian follicles results in an infertility citation called Premature Ovarian Failure (POF), affecting approximately 1% of women under the age of 40. Women with this disorder go through early menopause and have high levels of gonadotropin hormones (FSH & LH). Diminished Ovarian Reserve (DOR) is another infertility disorder in which women’s ovaries have the ability ...
