Product Information

In very rare cases, twins can be born physically joined together in different ways. These twins, called conjoined twins (previously called Siamese twins), can happen if the fertilised egg splits quite late after fertilisation.

Other reasonswhy twins and parents of twins might want to know whether they’re fraternal or identical include: Although identical twins have the same genes, they don’t always look the same. This is because children’s health and development are shaped not only by genes but also by experiences in the womb and after birth. For example, a twin who gets less blood from a shared placenta might weigh less at birth. Sharing a placenta or inner sac: why it’s important to know trying to work out the chance of having more twins in future pregnancies (only fraternal twins run in families) Triplets (1 in 5000 births) and quadruplets (less than 1 in 100 000 births) can develop as a result of combinations of fraternal and identical twinning. There are no reliable figures for quintuplets (5 babies) and sextuplets (6 babies). More about twinsThe birth rate of identical twins is the same around the world and doesn’t vary with the mother’s age. Very rarely, fraternal twins share a placenta. These types of twins are called chimaeric twins. Identical twins

Sometimes a woman’s ovaries release 2 eggs, and a separate sperm fertilises each egg. This forms twins. These twins are called fraternal twins, dizygotic twins (meaning two zygotes) or non-identical twins. During pregnancy, the developing babies get oxygen and food from their mother through the placentas and umbilical cords. Fraternal twins have separate placentas and umbilical cords. The technical name for this is dichorionic.

Fraternal twins

We would like to take this opportunity to thank you all for being so patient and understanding the past 7 months and for your continued support throughout these testing times, your the best 🤍 About one-third of identical twins split soon after fertilisation and form completely separate twins. Like fraternal twins, these twins have separate placentas. Sharing a placenta means that twins share a blood supplyduring pregnancy. Sometimes the blood supply is shared unequally, which can cause health problems for both twins.
