This should really be a no-brainer for me, but I am second guessing myself.

This individual hatched on 7/18/2010 from one of my adult pairs, so is over eight months old. I recently posted an ad for a 1.1 young standingi pair and it included this individual. I have long assumed it is a female, but the pictures are throwing me off. I have another individual produced in 2010 and it is undoubtedly male.

Here is the male:



My first three standingi were female, hence my question. There is some minor yellowing and the pores are confirming of a female, but the tail base looks questionable to me.



By eight months of age, I should be able to tell. Yeah, it has got to be a female.

The femoral pores are there, but with the males, there is a little opening in which secretions come out of. The one in question has tiny pin holes. But be patient, age is not necessarily the deciding factor. I believe that size has more to do with hormones than age does (within the first 2 years).

Thanks for your input. The tiny holes are why I think it is a female. My other hatchlings from last year are either clearly male or female at this point, even those similarly sized.

I have enough females to choose from, I just wanted to be assured of what I was seeing. New contact prescription needed, haha?

I was kindof thinking more towards male. But then again the last time I put in on a photo sex determination question I was wrong. Just felt like sharing my opinion!

I agree, time/size will tell. I can almost make out the begining of hemi penile bulges. Let us know how it turns out.

Female

Wait is that the same gecko from the first pictures? If it is WOW! What a difference. If it is the same gecko that last picture looks female.
