Could my male be a female?

I know weight can vary a lot depending on how well they eat. I have a male that's 16 months and 752 grams as of 7/18. He's in shed right now and I expect once I weigh him when he's done he'll have broken 800 grams. I see about 100 grams of weight gain or more a month and he's a good eater.
