No vascular changes perceived in uterine blood flow of women with dysmenorrhea

Novel research into mild primary dysmenorrhea or menstrual cramps has displayed surprising outcomes. Koray Özbay and Altuğ Semiz evaluated blood flow in the uterine and arcuate arteries in 55 women with dysmenorrhea and those without. They utilized transvaginal ultrasound to take Doppler measurements on days 1 and 2 and; at the 21st to 24th days (mid-luteal phase) of the menstrual cycle and compared the results between the two groups.

Contrary to expectations that ischemia (reduced blood flow) and vasoconstriction (narrowing of blood vessels) might be causing the pain, Doppler measurements showed no important differences between the two groups. The study, which hunted measurements during the early menstrual phase and mid-luteal phase, found that while the severity of dysmenorrhea was assessed using visual analogue scales, there were no notable variations in blood flow between those with and without mild primary dysmenorrhea.

As revealed mild dysmenorrhea may not be linked to decreased tissue perfusion, suggesting the need to explore alternative causes.
