if you have another male put him in the tank with her and let him secent up the place for a couple hours. watch to make sure they dont lock up if you dont want him to sire.
dont just put the other males skin in! i tried that didnt work for me. had to put another male in.
his smell will drive the other male crazy jealous and take his lady back.
its gonna take alot more than one or a couple lock ups till she is gravid.
and some lock up all the way till ovulation. keep it a little cooler-hot spot and take out the hides.
and anything else that they can rest behind or under.
just the water bowl.
try not to bother them much, and they'll do the rest.
edit: i forgot, if you know how to pop, pop another male and put his sperm plugs on her back, then introduce the first male back in with her,
that too will get his animal instinct to kick in and say "she's mine!"
oh you can also put some substrate from the 2nd males enclosure into her's to aid in scenting.
the first male will not stand for a female he thinks there's compitition for.
