I have been looking around trying to find out what the earliest age M Giant Day geckos can be sexed, some sources say 4 months, while the breeder I recieved my gecko from says 10? Anyone have any thoughts?

It' s more of a size thing. usally buy the time there 2-2.5" STV you can pick out wich ones will be males by looking at the peranal pores.

I've read that the larger gecko species don't reach sexual maturity until almost 18 months; however, I have 5 baby P. standingi (14 weeks, 10 weeks and 7 weeks) and I can already see some beginnings of femoral pores and a light yellow hue around the pore area or 2 of them which makes me think that those are males, and they are still pretty young. I'm split, I have 2 that are not showing any of those signs, thinking they may be females. I guess if they are growing fast (the oldest are almost 6 inches already), they may start showing earlier. It's my first time with babies so I don't know if they really are the sexes I think they are.

I am having the same problem. I have a smaller G.Day that is about 6in and 4-6 months, I thought that I could see some pores, and the yellow color is coming out, but I am not for sure if I am looking for the right thing.
