Identical Twins occur when a single egg is fertilized by a single sperm to form one zygote (monozygotic) but the zygote then divides into two separate embryos. The biological mechanisms that prompt the single fertilized egg to split in two remain a mystery. The two embryos develop into foetuses sharing the same womb.
Multiple eggs are released or there is more than one ovulation. Both (or more) eggs are fertilized and this is how fraternal twins are made. This can happen with or without fertility drugs. One egg is released but splits in two. This is how identical twins are made. This can happen with or without fertility drugs.
