Keep introducing them, let them lock, the activity of breeding can definitely stimulate follicles.

In addition, sometimes the female will retain the sperm until she feels like it. I had a female ovulate 6 months after locking up with a male ONCE, she laid a clutch of 9 perfect eggs. I have a girl now who's been locking up with anything with a hemipene (what a hussy) since last SEPTEMBER, no follicles, no nothing, but she'll still breed.

Figure as long as I have a male in good condition to breed her, I'll keep trying. She doesn't ever stop eating, is at an excellent weight, there's no reason she shouldn't breed...except she's my favorite, biggest, dinker female, and I just want her to REALLY bad.

I swear they know...
