What Researchers Did
Researchers studied whether daily hyperbaric oxygen therapy (HBOT) sessions could help thicken the uterine lining in women whose embryo transfer cycles kept being cancelled because their lining stayed too thin.
What They Found
A prospective pre-post cohort study of women with resistant thin endometrium found a statistically significant increase in endometrial thickness among patients who received daily HBOT for at least 10 days during the proliferative phase, with endometrial thickness measured at 5.76 ± 1.66 mm as part of that comparison. Propensity score matching was used to make the HBOT group and the concurrent control group more comparable, and both self-control and case-control comparisons were done. The study also tracked intrauterine pregnancy rate, embryo implantation rate, and miscarriage rate as secondary outcomes, but the abstract text available here does not include the numeric results for those outcomes.
Canadian Relevance
No direct Canadian connection identified; the study was conducted at a university-affiliated assisted reproductive medical center, and the author names do not indicate a Canadian institution.
Study Limitations
Patients volunteered for their group instead of being randomly assigned, which can introduce selection bias, and the study relied on propensity score matching rather than randomization at a single center to balance the groups.
