Growth rate determines gender?

[GrifTheGreat]

Hey guys. Just wondering if the growth rate determining gender thing is legit? I weighed my pyxie last week and he was 60 grams and today (exactly a week later) he is 77 grams. I weighed him before I fed him and have been feeding him between 5 and 8 crickets a day. I'm just wondering if this is a fast growth rate or not. Is that a typical rate for males? Or is it too early to decide. I posted pictures of him in my last post titled "My Pyxie Murphy" if any keen eyes wanna check them out and let me know what you think. Anything helps. Thanks guys.

Had the frog urinated prior to being weighed?

Not that I saw. Does that matter? I doubt he had 17 grams of pee in him.
