Keep in mind that I'm primarily a snake guy-but among lizard and snake breeders this is pretty common knowledge. For example, I've bred veiled chameleons for many years, and know from personal experience that if you miss the "mating window" with a female, you're in trouble. She will usually develop an infertile clutch, and half the time be unable to properly pass the eggs-leading to either a dead female or a high vet bill! The same can happen with snakes.

If you do a search of "infertile eggs" you should get quite a few references.
