:I have a leopard gecko and its a juvenile i've had it for about a month. Is there anyway to determine the sex right now?
It really depends what your definition of a juvenile is. Leopard Geckos are sexable with certainty around 6 + months of age, though some sources say 1 year. You can sorta distinguish sexes at a much younger age, but it's not 100% definite.
Here's a couple good links with info on sexing Leopards. The one below you'll have to copy and paste as you can only give one link per post. Take care.
