These terms were coined (long ago) by engineers to explain the subtle difference in system relationships to the non IT-literate, just as Male plugs & Female sockets were identifed thus for the actual illiterate a few centuries ago.
PC engineering started a long time ago, making me feel old. So BT, back in the late '80s informed engineering staff that we must not refer to M/F connectors as such, and under no circumstances call M/F convertors 'gender benders'. Being older and wiser, I see the issue with the last one, and convertor/adaptor generally works fine, but M/F is still widely used. It just ends up less ambiguous than trying to use alternatives like plug/socket, especially for cabling.
