【Abstract】 Objective:To evaluate the effect of letrozole in women with polycystic ovary syndrome by transvaginal ultrasound.Methods:A total of 38 cases with polycystic ovary syndrome were treated with letrozole,uteruses and ovaries were examined by transvaginal ultrasound and the serum reproductive hormone level was measured.Ultrasound parameters included the diameters of former and after cervix,the type and the thickness of endometrium,the number of dominant follicles,peak systolic velocity(PSV),end diastolic velocity(EDV),pulsatility index(PI),resistance index(RI)in uterus artery and ovarian stroma.Serum reproductive hormone included follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E2),progesterone(P),and compared with the control(n=52).Results:The ovulation rate(81.58%)and the pregnancy rate(21.05%)in the women with PCOS treated with letrozole were high.The blood flow of uteruses and ovaries were enhanced and changed periodically as normal women.Conclusion:Letrozole improved the blood flow of uteruses and ovaries in the women with PCOS and was available to pregnancy.更多还原
