Overview of prevalence, etiology, clinical features, diagnosis, and management of primary ovarian insufficiency

Abstract

Primary ovarian insufficiency (POI) is the development of primary hypogonadism before the age of 40 years in women with normal karyotypes. Patients present with symptoms that are similar to those of menopause, including irregular periods, reduced fertility, and climacteric symptoms due to hypoestrogenism, such as hot flashes, vaginal dryness, dyspareunia, irritability, and night sweats. The incidence of spontaneous POI is approximately 1 in 250 by 35 years of age and 1 in 100 by 40 years of age. Genetic, inflammatory, metabolic, autoimmune, and idiopathic factors contribute to POI. POI pathophysiology is explained by the presence of fewer primordial follicles and their rapid degeneration. Detailed history and examination are important for diagnosis. Diagnosis requires biochemical evidence and laboratory testing, including measurements of follicle-stimulating hormone, thyroid-stimulating hormone, prolactin, and estradiol (E2) levels. In addition, transvaginal ultrasound is preferred to evaluate ovarian reserve. POI should be managed through a multidisciplinary approach involving gynecologists, endocrinologists, and psychologists. Hormonal replacement therapy is the mainstay treatment for all women with POI. Lifestyle modifications such as weight-bearing exercises, smoking cessation, and Vitamin D and calcium supplementation are highly recommended to improve bone density and reduce fractures. Psychological care has been suggested to improve self-esteem and social support, along with family planning guidance. Despite recent discoveries, additional screening techniques are needed.
