Laser zaps endometriosis cysts: could this spare fertility?

This pilot study investigates how well a dual-wavelength diode laser can destroy endometriotic tissue inside ovarian cysts (endometriomas). Researchers will apply the laser to cyst walls removed during surgery and examine the tissue under a microscope to see if all abnormal cells are killed and how deeply the laser penetrates. The goal is to gather data that could lead to a surgical technique that preserves ovarian function better than current methods. About 30 women having laparoscopic surgery for ovarian endometriomas will provide tissue samples for this ex vivo analysis.
