NCT06042348

Brief Summary

Ultrasonography will be used to determine the total blood flow to and from the uterus. This is done by measuring the blood vessels coming from and going to the uterus. This wil hopefully prove viable and open the possibility to further research in the clinical relevance of these measurements.
