The sperm plug is associated with the male's hemipenal sac. They start to produce them after they have reached sexual maturity. I believe my first male started producing them at a weight of 500 and age of 1 years old. My other snake did not start producing them until a weight of 900 and almost 2 years old. There again I only saw them on sheds. I do not "pop" the hemipenis, so I have not seen them in this way, only in sheds. In short the sperm plug is simply a brownish, dry string-like accumulation of dead sperm.
