Mice used to have a mechanical ball in the bottom. You needed to remove it periodically to clean out the gunk that formed on the rollers. When optical mice appeared, they steadily replaced the old style. It became an IT joke. Mice with balls were male. Optical mice were female.
Old stock, or is someone still making them?
We are talking about their ports right? All mice I have used had male ports or bluetooth dongles.
