ABSTRACT

Objective　To observe the relationship among the degree of maturation of development of ovarian follicle and endometrial thickness and resistance index of uterine helicine arteries.Methods　Fifty six cases of normal menstrual cycle were studied by transvaginal color Doppler flow imaging.Results　Diameter of ovarian follicle increased and moved to the surface of ovary before ovulation,endometrium thickened and resistance index of uterine helicine arteries decreased.Conclusions　Observation of the development of ovarian follicle by transvaginal color Doppler flow imaging is helpful to improve regnancy rate.
