Heats: Difference between revisions

Eggs can still release and be fertilized outside of heat, but will usually stay in the fallopian tubes/uterine horn until sex during heat allows them to soak up enough hormones to jumpstart development. (This means that a litter with multiple different sires is possible, though fertilized eggs may have decreased receptivity to seminal hormones from a different sire. Research is still ambiguous.) Pregnancy outside of heat is unlikely, but possible. Fertilized eggs are usually lost if the next heat doesn't include sex. But singleton (one child, like our world, with the same possibilities for twins, etc) eggs may develop without seminal hormones. This usually begins immediately after conception, when the eggs continue to the uterus rather than staying put.
