Popping takes practice to get right, and can harm the snake if done incorrectly.

Probing requires sterile instruments (you can buy a set from reptile basics) you insert the probe into the vent to see how far it will go in. Be very gentil as pushing to far/hard can hurt the snake. A female will only let the probe in a very short distance, and a male will go in a much larger amount. Again watching a video online or seeing someone who knows what they are doing is very important.

I just gave an extremely basic overview of both methods, I would advise that you do more research before you attempt either method as they can both end in harm to the snake when done improperly.
Thanks that's the info I was looking for I have started looking at some vids but im afraid to attempt anything myself. I dont know of anybody in the area that can do it. good reptile stores and breeders are scarce up here in washington. I will keep on keepin on though as I hope to be breeding my pastels next year and will have to know how to properly sex the hatchlings.
