What are the odds that BP males lock?

What I mean is when you pop and it comes out a male then you know for sure 10% it is a male. But if it pops a female then it could just be a stubborn male not popping out so you see no hemipenes so you say it is a female.

On the flip side, it's very possible to injure a female when probing. That female will then always probe "male." The only guarantee is eggs, but I personally find popping to be a safer method for sexing, even adults. If the OP is successfully popping his other males, then it's probably fair to assume he is doing it properly.

I think you meant if you pop a male and see his hemipenes it is 100% male. From what I hear some males and females probe deeper and some shallower so it cant be 100% accurate, plus even an attempt at a stubborn male will more than likely still pop out the hemepene cast even if you cant pop his hemepenes all the way out.
