Twin Pregnancy

While multiple pregnancy accounts for only 3 percent of all live births, they account for 17 percent of all preterm births, 23 percent of all early preterm births (less than 32 weeks), and over a quarter of all low birth weight infants. While preterm delivery is clearly the most common consequence of multiple gestation, there is also significantly increased risk for foetal growth restriction, congenital malformation, cerebral palsy, and other long-term handicaps related to preterm birth.

Women who are pregnant as a result of either ovulation induction or in-vitro fertilization are at much higher incidence of monochorionic twins, or twins which share a single placenta. Though our Fertility team in motherhood take due care to avoid such complications and ensure single embryo growth during the cycle.

If you are pregnant with twins or triplets, it is strongly advised you deliver in a hospital. Motherhood Hospital will take take care of the extra risks involved. If you are in a hospital setting, if there is a problem, it can be more rapidly diagnosed and dealt with. This way you are more likely to have a safe delivery, and your babies have the best chance of being healthy.

Whether you have a vaginal or delivery by an operation (a caesarean section) will depend on several factors. This includes:


·         Preference of patient.

·         Triplets and more are almost always delivered by caesarean section.

·         Which way around your babies are. If the first baby is ‘head down’ near the time of delivery, you may usually choose to have a vaginal delivery; however, if both babies are ‘breech’ you may be advised against it.

·         If the babies share a placenta, you are most often advised to have a caesarean section.

·         Whether you have had a caesarean section in the past or not.

·         Associated complications in your pregnancy (for example, high blood pressure, pre-eclampsia, HELLP syndrome, eclampsia).

·         Whether the babies become stressed during labour. If the heart rate of either baby slows down, it may become vital to get the babies out quickly.


Identical twins (Dizygotic twins) : Early in the development phase, egg split into two or more baby-generating zygote, so they will be the same sex.

Non-Identical Twins (Polyzygotic Twins) : Egg is fertilized by different sperm, basically genetically different sibling growing in the same womb.

Multiple pregnancy is usually first recognised at your first ultrasound. For most women, this is when you are 11-13 weeks pregnant the number and frequency of your scans will depend on your individual circumstances. Scans allow Motherhood’s antenatal team to check your babies are growing as they should, and early detection of some of the problems twin babies can experience
