Summary

This study looked at 160 men with azoospermia (no sperm in semen) to see if a special PET scan (FDG PET-CT) could tell which men would have sperm found during testicular extraction. The scan measures how active the testicles are. The goal was to compare scan results between men who had sperm retrieved and those who did not. This could help avoid unnecessary surgery in the future.
