[Research progress on roles of vitamin D in endometriosis]

In addition to regulating calcium and phosphorus metabolism to maintain strong bones, vitamin D also has immune regulating and anti-inflammatory effects. Moreover, it is related to chronic inflammatory diseases, autoimmune diseases and cancer. Many studies indicate the roles of vitamin D in the development and progression of endometriosis including the effects on modulation of immune responses, inflammation reactions, cell proliferation and apoptosis, angiogenesis, adhesion and invasion. Vitamin D supplementation can relieve pain and improve endometrial receptivity associated with endometriosis and play a preventive and therapeutic role. This paper summarizes the roles of vitamin D in endometriosis.
