Real-time intrauterine dissolved oxygen dynamics across the luteal phase: a potential non-invasive functional biomarker of endometrial status
Listen to this summary
The authors investigate whether real-time measurements of intrauterine dissolved oxygen (pO₂) during the luteal phase could serve as a non-invasive biomarker for assessing endometrial readiness in women undergoing assisted reproduction. Their pilot study identifies distinct oxygenation patterns, with some participants exhibiting a mid-luteal peak in pO₂, which may correlate with endometrial function. The findings suggest that further research is needed to validate the predictive value of intrauterine oxygen profiling for implantation success and live birth outcomes.
