Reptiles go dormant for many reasons, temperature change, lack of food, or safety.
Every reptile Ive ever seen, had, or cared for that reproduced did so because conditions allowed for it, in other words it was conditions. I can get my big albig to go dormant a few times a year by doing nothing different, but there are times I must add or subtract litebulbs to her cage or she will do so. Once that process starts it is too late to prevent it, but they stay dormant for a short time (days to a week) and come back up to the new more suitable condtions, then readjust to eating normal again.
As far as bigger clutches, not a chance. Ive seen snakes and lizards that were brumated that lost entire periods of time recovering. They always produced less eggs per clutch and less clutches, and were of a smaller body weight consitantly.
