I don't see any reason they need to be asked in the same article actually. Was there ever a time when 40% of primary school teachers were male? It's not clear to me that there's any strong parallel between the two professions at all.
It is a good question to ask though, as there are societal pressures against men going into any profession related to children (e.g. the pedophile scare). But asking it _here_ is just cheap whataboutery to silence the discussion.
