OBJECTIVE: To investigate the effects of Er Xian Decoction (EXD) and its three subdivisions "warming Shen" ,"nourshing Yin" and "adjusting Chong and Ren" in regulating the level of estradiol (E2) on the primary cultured granulosa cells. METHODS: Effect of EXD and its three subdivisions, also part of the effective components of this formula, icariin and curculigoside, on level of E2 were carried out using primary cultural granulose cell as the experimental model. RESULT: EXD and its three subdivisions could stimulate the secretion of E2, especially the "warming Shen" group (P <0.05). All the composing of Chinese herbs of this formula could promote the level of E2 in different degree, and the Rhizoma Curculiginis, Radix Moromade Officinalis, and Herba Epimedii have the best effects (P <0. 01). CONCLUSION: The regulation of EXD on the hypothalamus-pituitary-gonad (HPG) axis may be related to promoting the secreting of E2 at the site of granulosa cell. The "warming Shen" subdivision has the better effect in promoting the secretion of E2.
