Blood biomarkers may help avoid unnecessary surgery in boys with testicle issues

This study looked at tiny molecules in the blood called miRNAs to see if they could help doctors tell apart two similar conditions in boys: undescended testicles (which need surgery) and retractile testicles (which usually get better on their own). Researchers took blood samples from 28 boys and measured three specific miRNAs. The goal was to find a simple test that could reduce unnecessary surgeries and improve care.
