In plain language
In a small case-control study of 60 men, radiology workers with occupational radiation exposure had lower sperm concentration, more abnormal sperm, higher NK cell levels and reduced TNP1 expression than controls. These are associations, and radiation doses were not reported.

What it found
Radiology workers with occupational radiation exposure had significantly lower sperm concentration and more sperm morphological abnormalities than controls.
Key figures: p < 0.05
NK cell concentration was significantly higher in the exposed group.
Key figures: p < 0.001
TNP1 expression was significantly decreased in exposed men.
Key figures: p < 0.001
TNP2 expression was reduced in exposed men, but the reduction was not statistically significant.
Gene expression profiles showed only weak to moderate correlations with selected sperm parameters.
Limits to keep in mind
Small case-control study (30 exposed, 30 controls) with no reported radiation dose data, specific job roles, country or confounder adjustment in the abstract, so findings show association, not causation. Participants are radiology workers broadly, not specifically interventional fluoroscopy teams.
