How does multiple pregnancy occur? A twin, triplet, or higher-order pregnancy (four or more babies) is called multiple pregnancy. If more than one egg is released during the menstrual cycle and each is fertilized by a sperm, more than one embryo may implant and grow in your uterus. This type of pregnancy results in fraternal twins (or more). When a single fertilized egg splits, it results in multiple identical embryos. This type of pregnancy results in identical twins (or more). Identical twins are less common than fraternal twins.
