I feel that a male may not always be there at the correct moment in the wild. So the females can control ovulation once she has copulated. I have had great results this year minus a few hiccups, but soon realized that the infertile clutches that I had were where the females only had access to a hot spot of 80. (Also, my gentilis pair was together and the male and female both had access to 86)(Plus my aberrant knob that just seems to want to shoot blanks)

Interesting take. The general consensus, which I'm not married to, is that males are more fertile if allowed to cool which was basically modeled after broad observations of what is largely perceived to be seasonal breeding in wild snakes (at least NA colubrids). Frank's take is that if you allow access to cool the males will opt to use it without some outside cycling factor and be ready to breed if all other conditions right. My problem is getting the other conditions right so that this happens without outside influence on my part (short of putting them in a cage). I'm thinking that a single male environment is certainly a factor in male behavior but my enclosures just aren't big enough to accommodate more than a pair or trio so I'm opting for some form of cycling to get them in sync.
