What Researchers Did
Scientists tested whether hyperbaric oxygen treatment could reduce tissue damage in rats after a surgically induced and then untwisted ovary (a model of ovarian torsion).
What They Found
This animal study compared rats that had torsion and detorsion surgery alone to rats that also received hyperbaric oxygen treatment (100% oxygen at 600 kPa for 50 minutes, given 21 times), and found lower markers of oxidative damage in the treated group. Two markers of cell damage, 8-hydroxy-2'-deoxyguanosine and malondialdehyde, were lower in the hyperbaric oxygen group compared to the torsion-detorsion-only group. Anti-Mullerian hormone, a marker of ovarian reserve, was higher in the hyperbaric oxygen group. Tissue samples from the hyperbaric oxygen group also showed less swelling, less blood vessel blockage, less immune cell infiltration, and less damage to egg-containing follicles than the torsion-detorsion-only group.

Study Limitations
This was a small animal study (7 rats per group) using laboratory measurements and tissue analysis rather than human clinical outcomes, so the findings may not translate directly to people.
