the same thing happended to me. a year of so ago I bought an 08 "male" mojave. well last season I tried pairing "him" up with several females and was not interrested whatsoever. I tried popping and no hemipenes or sperm plugs came out but when I probed it seemed to probe male. so a month or so ago a friend of mine came over and confirmed what I suspected. female!...she's been a sporatic eater is in the 800 g range but should be ready for next year. and to think I almost traded her for a few normal breeder females..
