Why the Minions were designed as male?

apparently the Minions are all male because the creators wanted them to feel like little childlike sidekicks, not a mixed-gender cast.

“Little childlike sidekicks” is doing a ton of work as an explanation. Did the article say what they were actually trying to avoid if even one Minion read as female—like the jokes shifting, merch/marketing getting weirdly gendered, or the whole group dynamic getting interpreted differently? not sure, might be wrong.
