I get why Nidoqueen won't be able to breed due to menopause and because she's past her age of breeding but why the fuck nidoran loses her breeding capabilities when evolving into nidorina? what's the logical explanation for that? many times we see nidorino and nidorina being paired just like nidoking and nidoqueen but apparently it's not possible for either pair to breed and it's not something gamefreak even bothered to fix or retcon? it seems so farfetch'd that they simply came up with this description and stick with it without any further explanation
