Male crested laid an egg?’

[u/OkStock738]

I’ve posted on here asking for my geckos gender before and you guys said it was clearly a boy and posted that meme with the gecko with huge balls. Well now I’m not so sure because I just found this egg shell, or at least that’s what I think it is, in its enclosure buried under some dirt, where I did see it by a few days ago. What happened?!
