Women with a normal menstrual cycle (n = 21, controls), polycystic ovary syndrome (n = 10) and hypogonadotropic amenorrhea (n = 3) were stimulated with clomiphen‐citrate (4th day to 8th day of the cycle) and with human menopausal gonadotropin (8th day to 11th day). The vascular impedance of the ovary carrying the dominant follicles was monitored by endovaginal pulsed Doppler flow measurement. Simultaneously, serum levels of LH, E 2 and 17‐OHP were assayed. Contrary to controls, women with polycystic ovary syndrome or hypogonadotropic amenorrhea showed decreased hormone levels and no lowering of the vascular impedance. In controls, the lower pulsatility index is caused by neovascularization around the dominant follicle and by E 2 ‐induced vasodilatation in the ovarian artery. © 1993 by John Wiley & Sons.
