At a reptile show I was talking about Western Hognoses with a breeder there. We were only discussing males as I was wandering when they reach sexual maturity just from my own self-interest. The breeder told me that he starts using his males males that he raises to breed at 200 grams. He also said some may reach this target quicker and others may take longer. As for females he told me but I put the info in the back of my brain because I don't intend to breed any of my snakes until I graduate college.

Hope this helps somewhat.
