Would a ascending urethrogram study has any effect on fertility as radiation is directed towards the genitals ? it's the second one that i'm having

Backward urethrogram: Should not require 2nd retrograde urethrogram provided 1st performed correctly. Study usually performed to diagnose or localize urethral stricture. 2nd study not required to evaluate post-operative correction of stricture. Simple uroflow study gives all information required as location of stricture demonstrated at 1st study! Radiation from couple of urethrograms should not affect fertility
