I’m from the US, but here it’s mostly fraternal lodges that still ban women, and certain religious groups(which I don’t think those technically count due to separation of church and state). But the Order of Oddfellows, Fraternal Order of Eagles, Freemasons, and the Botherhood of St Andrew don’t initiate women. Im sure theres more but i dont know about them.
Granted those have some religious influence, but aren’t churches directly as far as I understand. Also the skull and bones, but they’re very secretive and that could have changed and no one would be the wiser.

I’m not sure about other countries laws, but in the US private institutions are more or less allowed to segregate by gender, but often there’s backlash and they lose money so most won’t go there. That’s why it’s mostly these secretive fraternal orders that still do it.
