Title: Which do You Think is the Best Treatment Choice in Primary Dysmenorrhea?
Brief Summary: Our aim is to evaluate and compare the pain relief of estradiol valerate/dienogest and ethinylestradiol/ drospirenone by using doppler indices.

100 nullipara patients with symptoms of severe primary dysmenorrhea (PD) requesting contraception aged from 18 to 35 were included to the study. Visual analog scale (VAS), the uterine artery doppler indices including systole/diastole rates ( S/D), pulsatility index (PI) and resistance index (RI) values were evaluated and recorded in both uterine vessels before treatment. The 66 PD patients who met the inclusion criteria were divided into 2 groups and 33 healthy controls created Group 1. Group 2 were administered estradiol valerate/dienogest while Group 3 were administered 0.03 mg ethinylestradiol and 3 mg drospirenone. Both VAS scores and doppler indices were repeated after 3 months treatment. The changes in values were recorded.
