Early pairings and year round breeding

Hi all! I've been reading up on ball python breeding, and I'm unclear about a couple concepts...

On the typical ball python breeding schedule, what is the purpose of early pairings in fall/winter? Does it stimulate ovulation and spermatogenesis, or is it just part of the mating ritual leading into spring, or is there another reason?

On the subject of breeding year round, "out of season", if you will: is it still necessary to have these initial pairings for a few months before actual fertilization occurs?

Thanks all...:)

The short answer is yes. You need initial pairings regardless of what time of year because it can drive the process of follicle development and ultimately ovulation. If there is no pairings, the female may still develop follicles but it will likely be just on her own natural schedule. Most people try and keep it around the regular season in the wild, but they can breed anytime of year.
