Banana male female maker price and availability?

Has anyone seen or purchased a banana male female maker? Meaning, a male Banana from a clutch from a banana female. I haven't seen any advertised, and was wondering if anyone has seen or purchased one and what the prices might be.

Are they selling for more than females I wonder?

I'm not sure
