What Researchers Did
Researchers conducted a randomised controlled trial involving 32 women with unexplained infertility to evaluate the effects of hyperbaric oxygenation on endometrial development, thickness, and perfusion using transvaginal color Doppler sonography.
What They Found
They found that hyperbaric oxygen therapy significantly improved endometrial quality (p<0.001), with an average endometrial thickness of 11.0 +/- 2.6 mm at ovulation in the treated cycle. This indicated an excellent endometrial response to the therapy, although uterine blood vessel resistance was slightly higher than expected.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A key limitation of this study is its small sample size of 32 women, which may limit the generalizability of the findings.
