Triplets are a type of multiple birth where three offspring are born at the same time. They can occur naturally or through assisted reproductive technologies. Triplets can be identical, fraternal, or a combination of both. Identical triplets come from a single fertilized egg that splits into three, while fraternal triplets result from three separate eggs being fertilized. The chances of having triplets are relatively low, but factors such as maternal age, genetics, and fertility treatments can increase the likelihood. Triplet pregnancies often require special medical care due to the higher risks involved for both the mother and the babies.
