Premature ovarian failure: Immunological aspects and therapeutic strategies

Genetic Aspects of Premature Ovarian Failure

[Genetic aspects of premature ovarian failure].

Among the causes of premature ovarian failure (POF) two groups of factors are reported: factors which lead to decrease of follicular number and factors which stimulate follicular atresia. In the first group genetic factors are the most important whereas in the second: enzymatic autoimmunological, iatrogenic, toxins and infections are reported. In 1986 familiar POF on the background of long arm ...

Ovarian aging and premature ovarian failure.

Physiological reproductive aging occurs as a result of a decrease in the number and quality of oocytes in ovarian cortex follicles. Although the reason for the decrease in the quality of the pool and follicular oocytes is not fully understood, endocrine, paracrine, genetic, and metabolic factors are thought to be effective. Nowadays, in order to understand the mechanisms of ovarian aging, genom...

Autoimmune premature ovarian failure

Premature ovarian failure (POF), also termed as primary ovarian insufficiency (POI), is a highly heterogenous condition affecting 0.5-3.0% of women in childbearing age. These young women comprise quite a formidable group with unique physical and psychological needs that require special attention. Premature ovarian senescence (POS) in all of its forms evolves insidiously as a basically asymptoma...

Premature ovarian failure

Premature ovarian failure is defined as a primary ovarian defect characterized by absent menarche (primary amenorrhea) or premature depletion of ovarian follicles/arrested folliculogenesis before the age of 40 years (secondary amenorrhea). Hormonally, POF is defined by abnormally low levels of estrogen and high levels of FSH, which demonstrate that the ovaries are no longer responding to circul...
