Talk:Krogan

These secondary systems are capable of serving as back-ups in the event of damage to the primary biological structures (and also means krogan males have four testicles).

Is the testicles comment fact or conjecture? Perhaps humans are the only species to possess 2 and more or less is common. Unless I missed something and it is explicitly stated somewhere that 2 is the norm, I move that the parenthetical be erased.
