Will egg retrieval worsen endometriosis?

For many patients, egg retrieval and the IVF stimulation that comes with it do not appear to dramatically “accelerate” endometriosis in the short term—even though estrogen levels can rise significantly during stimulation. That said, it’s common to feel worse temporarily: ovarian enlargement, inflammation, and pelvic pressure can trigger pain flares, and symptoms may feel more noticeable once you’ve been off hormonal suppression to pursue pregnancy.

The main caveat we take seriously is deep infiltrating endometriosis and patients with significant baseline symptoms, where limited data suggest stimulation may contribute to progression in some cases. In real life, the decision is often a balance: IVF may help you move toward pregnancy sooner and reduce the total time you’re off symptom-controlling therapy, but the plan should be individualized around your disease pattern, endometriomas, prior surgeries, and quality-of-life goals. If you’re weighing egg retrieval and worried about symptom escalation, our team can help you think through timing, coordination with fertility care, and whether treating endometriosis surgically first (or after retrieval) makes the most sense for your body and timeline.
