Twin Pregnancy
Twin pregnancy is a special type of pregnancy in which two fetuses develop simultaneously in the uterus. It is usually detected during an ultrasound examination in the early stages of pregnancy, and apart from joy, it may also cause concern for the expectant mother, as it is by definition a high-risk pregnancy. This is precisely why it requires more systematic and specialized monitoring. With proper information and specialized management, a twin pregnancy almost always progresses smoothly and safely for both the mother and the fetuses.
What Is Twin Pregnancy and What Are Its Types?
It is important to understand the type of twin pregnancy, as this affects both the monitoring and the likelihood of complications. Twin pregnancy is classified into two main categories, depending on the mode of fertilization. More specifically:
- Dizygotic (non-identical) twins: These occur when two different eggs are fertilized by two different sperm cells. The embryos have different genetic material, may be of the same or different sex, and each has a separate placenta and amniotic sac.
- Monozygotic (identical) twins: These result from the division of a single fertilized egg. The embryos have identical genetic material and the same sex. Depending on the stage at which the division occurs, they may share the same placenta or even the same amniotic sac.
This distinction is crucial for the monitoring approach and the prognosis of the pregnancy.
Twin Pregnancy: Incidence Rates
Twin pregnancy does not occur with the same frequency in all women. There are certain factors that appear to increase the likelihood of its occurrence, without however guaranteeing it. These include:
- Heredity, mainly from the maternal side
- The woman’s age, particularly after 35 years
- Assisted reproduction treatments, such as in vitro fertilization (IVF)
- Number of previous pregnancies
At the same time, many twin pregnancies occur without a clear predisposition.
Monitoring and Specific Considerations in Twin Pregnancy
Twin pregnancy is classified as a high-risk pregnancy due to the increased likelihood of complications during gestation. In this context, the expectant mother should visit her gynecologist more frequently compared to a singleton pregnancy, as ultrasound monitoring plays a crucial role in the early detection of pathologies and their safe management.
Particular importance is placed on close monitoring of the growth of each fetus individually, placental function, and the volume of amniotic fluid. Screening for structural abnormalities and syndromes is also of special significance, as well as the early recognition of clinical signs that increase the risk of preterm birth. Equally important is the careful monitoring of the pregnant woman, particularly regarding signs of hypertension, metabolic imbalance, and during the perinatal period.
Potential Risks and Complications
It is important to be aware of the potential risks that occur more frequently in a twin pregnancy:
For the fetuses:
- Preterm birth
- Low birth weight
- Intrauterine growth restriction (IUGR)
- Growth discordance between the twins
- Congenital anomalies
- Perinatal morbidity
For the pregnant woman:
- Anemia
- Hypertension / preeclampsia
- Gestational diabetes mellitus
- Bleeding during pregnancy
- Increased rate of cesarean section
- Uterine atony
Despite the increased risks, most twin pregnancies progress smoothly when there is specialized and regular medical monitoring.

Mode and Timing of Delivery
The mode of delivery depends on whether the fetuses share the same placenta and/or the same sac, the position of the fetuses, any complications during pregnancy, and the overall condition of the mother.
In general, when the fetuses have separate sacs and separate placentas, the first fetus is in cephalic presentation, there is no significant size discordance, and the pregnancy has progressed smoothly, vaginal delivery is possible.
The timing of delivery in twin pregnancy differs from that of a singleton pregnancy.
Indicatively, in uncomplicated dichorionic (two placentas), diamniotic (two sacs) twin pregnancies, planned delivery is recommended between 37+0 and 37+6 weeks. Continuation of pregnancy beyond this point has been associated with increased perinatal complications.
In uncomplicated monochorionic (one placenta), diamniotic (two sacs) twin pregnancies, planned delivery is recommended between 36+0 and 36+6 weeks for the same reason.
The couple should discuss with their gynecologist and prepare appropriately for the upcoming delivery. With proper medical care, twin pregnancy results in the birth of two healthy children and an entirely positive experience for the whole family.
