Endometriosis affects about 190 million women and girls worldwide, and around 10% of people who menstruate are impacted during reproductive age. Even when symptoms seem clear, the tests can tell very different stories, with laparoscopy confirming endometriosis in 75% of suspected cases while ultrasound finds endometriomas with 90 to 95% sensitivity. This mix of detection rates, symptom burdens, and treatment responses is exactly why the numbers are worth comparing side by side.
