Oh yea, that kind of breeding often makes your entire PC full if you're not releasing pokemon constantly.

Yeah, I only tried Masuda breeding once - for Fennekin, as mentioned - and that's why after a while I just started releasing all the males. It became too tedious to wonder trade all of them so I just tossed all the males out outright, firstly to clear up a lot of space and secondly because the females are a bit more valuable, so I'd feel like I was giving out nicer prizes.
