Input: Question: Does raloxifene therapy affect uterine blood flow in postmenopausal women : a transvaginal Doppler study?
Answer: In the group studied here, raloxifene treatment at the dose of 60 mg per day for 6 months did not induce significant changes in endometrial thickness, uterine volume or uterine artery perfusion, confirming that short-term raloxifene treatment does not affect the uterus of postmenopausal women.
Output:
no
