to search for model of laboratory animal suitable for facilitation of evaluating follicular development and ovulation by tonifying kidney and removing stasis. Method:several parameters were observed and compared between the model of ovulation inhibition induced by pure lutin contraceptive(LNG) or Guixi Decoction and the normal control group, for instance, blood rheology, blood serum E2, P, index of ovaries and hystera, growing follicle of ovaries, vesicula graafianae, corpora atretica, amount of corepus luteum, etc. Result:the model groups presented with a rise in blood viscosity, amount of growing follicle and corpora atretica to varied degrees, a marked decrease in amount of corepus luteum and depression of lutin level. Guixi Decoction group appeared significant change in blood rheology; lutin group was notable in arresting ovulation. Conclusion:animal model of arresting ovulation induced by lutin or Guixi Decoction could be used to study drug action and therapeutic effect for ovulation-facilitating medicine with the nature of tonifying kidney and removing stasis.
