i have been unfortunate enough to have suffered violent incursions to the tender region and i think dismemberment would be less painful :)

as i said i would have thought they still had testicles, and as you said, enhanced, conditioned, drugged supersoldiers, but amongst all the severe genetic reconfiguration a human goes through to become an astartes i imagine withdrawing testicles into the pelvic cavity wouldn't be too much of a chore and would provide considerable security for the jewels.

an analogy could be - a punch in the face will hurt but conditioning can help to move through/ignore the pain. wear a headgaurd and the punch could still hurt but it's mitigated somewhat by the headgaurd. in the theatre of war and in terms of astartes wouldn't it make sense to protect as much as possible?
