No. I understand if you allow the female adult dragon to brumate over winter, even if she never see's a male, she will likely still produce a clutch of slugs.
My Peppa never laid slugs , nor did Rex.
None of pet skinks or dragon have ever brumated , though they do slow down a little over winter but are awake each day looking for food, (water for the skinks) and basking & wanting out).
I've nearly always had mixed sex pairs who are housed separately and never allowed to physically meet (to do the deed) , they do show an interest in the other lizard (potential mate) and do courting rituals but that's as far as I let It progress.
