Apoptotic mechanism of premature ovarian failure and rescue effect of Traditional Chinese Medicine: a review.

Social and environmental factors render premature ovarian failure (POF) as a major cause of decline or loss of female fertility. The natural pregnancy rate of patients with POF is only 5%-10%. Follicular atresia is the main factor in the pathogenesis of POF. Due to the unique ovarian physiological environment and follicular developmental processes, the apoptosis of ovarian granulosa cells and oocytes together cause follicular atresia, which involves the apoptosis-related internal and external pathways. Furthermore, during POF, apoptosis and oxidative stress forms a ""vicious circle"", which involves a variety of changes between the molecules. The existing pharmaceutical preparations such as gonadal hormones are the basic methods for the treatment of POF, and the curative effect was affirmative; however, it was ineffective after withdrawn, while the long-term application led to adverse reactions. Traditional Chinese Medicine (TCM) has a history of treating gynecological diseases and infertility and has gained increasing attention. Studies have shown that compounds isolated from herbal medicine exerted a positive effect on follicular atresia caused by cell apoptosis that also improved the POF. The present study reviewed the mechanisms underlying the apoptosis in POF and elaborated the internal mechanism of TCM in the treatment of the condition.
