Main conclusion
Low-intensity pulsed ultrasound reprogrammed macrophage responses and reduced fibrosis in a mouse model of endometrial injury. The study identifies an interesting direction for intrauterine-adhesion research, but it does not provide a treatment protocol for women.
What the study did
The authors reported reduced M1 macrophage polarization, increased SOCS3 expression, and attenuation of JAK1/STAT3 and TGF-β/Smad3 signaling. Endometrial remodeling and fertility improved in animals. Human fibrotic endometrial samples showed lower SOCS3 and STAT3 hyperactivation, but women did not receive the intervention.
Key limitations
Reproductive efficacy was demonstrated only in mice. The clinical dose, safety for human endometrium, implantation effect, and live-birth outcomes are unknown. Confirming part of the pathway in human tissue supports biological plausibility, not therapeutic efficacy.
What can be said to patients
LIPUS should currently be described as a promising preclinical technology. It should not be offered as a proven treatment for adhesions or implantation outside a properly designed clinical trial.
