Can an endometrioma rupture during ovarian stimulation?

Yes—an ovarian endometrioma can rupture during ovarian stimulation, although it’s not the most common outcome. Stimulation can enlarge the ovaries and increase pressure within the pelvis, and an endometrioma is a fluid-filled cyst that can be sensitive to stretching, inflammation, or mechanical stress. If a rupture happens, people often describe a sudden, sharp one-sided pelvic pain that may be very different from their usual “endo pain.”

Because several urgent problems can look similar during stimulation (like ovarian torsion, bleeding, or infection), the key is not to guess the cause based on symptoms alone. Our team can help you sort out what’s most likely in your situation using a careful history and targeted imaging—especially ultrasound and, when helpful, expertly interpreted MRI—so you know whether you’re dealing with an endometrioma complication or something else.

If you’re planning IVF or are already in a cycle and you have a known endometrioma, it’s worth proactively mapping out a plan for monitoring and next steps if pain escalates. We can also walk you through fertility-conscious options that may be appropriate for selected patients, including less invasive approaches when the goal is protecting ovarian tissue while still reducing endometrioma-related risk and symptoms.
