Aim: To conduct a systemic review of published data on reference values for both transabdominal and transvaginal ultrasound in gynecology.

Materials And Methods: Literature from 1970 to 2020 of reference values for the female pelvis in healthy subjects was reviewed. According to the determination of reference intervals for laboratory values reference values are generally determined using 95%-reference intervals and their associated 90%-confidence intervals.
