Technically it is not. As stated above a sperm plug is a waxy deposit that a male leaves after mating with a female to prevent another males sperm from reaching the females oviducts. Garter Snakes use sperm plugs.

What we see in Ball Pythons should be called a hemipenial "cast". It is dried up hemipenial shed,dried mucus with probably a dash of the reptilian equivilant to smegma.
Ok, so you're saying that this hemipenal shed is still an indicator for letting us know the male is producing sperm and can properly breed?
