We can only speculate what caused the kink. Is it male or female?
Probing rarely causes reproductive compromise, even when perforation takes place (there are references to it, I just don't have them on hand).
If the kink is directly above the cloaca, it can (but may not) compromise the mating mechanics, particularly in males.
It is a girl. Well a probe count of 5 anywayMate, I wouldn't worry about it too much.
You still didn't tell us whether it's a male or a female, but it's probably not that important. The kink is not huge, in fact, I have a theory about thin but ..... next time.
