As the name indicates, in a singleton pregnancy, one child gets born in the womb of the mother during her pregnancy.

When You Get Pregnant

A general practitioner or an obstetrician will confirm your pregnancy. There will be a comprehensive medical history interview, some series of blood tests and an ultrasound. The practitioner will then refer you to the maternity unit where you can book an appointment for the 20th week.

Can A Singleton Pregnancy Turn into Twin Pregnancy?

The best possible way to find out if you are going to have twins instead of a singleton pregnancy is to go for the ultrasound at 10th week. Multiple births are now happening at a more significant rate in the United States. This totals to 3.5 percent of the total pregnancies occurring in the country.

What Is Singleton PregnancyThere are multiple signs that predict you are not going to have a singleton pregnancy. It is, however, important to consider that these symptoms vary from individual to individual. These signs and symptoms are:

High hCG

This is the pregnancy hormone. It can get higher than the normal rate when you are not having a singleton pregnancy.

High Weight Gain

Women who carry twins might gain a lot of pounds in the first trimester in comparison to the women having other pregnancy.

Bump of Bigger Size

Pregnant mothers having twins have a larger bump than mothers carrying a single child.

Fetal Movement and Outcome of Birth

Women that carry twins might see fetal movement a lot earlier in comparison to mothers who carry a single baby.

Abnormal AFP Test

A positive AFP test determines the twin pregnancy case in pregnant mothers. This test also detects different birth defects.

Singleton Pregnancy and In Vitro Fertilization

In-vitro Fertilization or IVF came into a function from 1978. Since 1978, a total of 3 to 4 million babies are born through the help of In Vitro Fertilization. This is just the tip of the iceberg when we are talking about methods of reproduction.

Many scientists have been trying to investigate its outcome since it came into function. Many studies evaluated the effect of the IVF on the mother’s health who is undergoing the regime. Studies have built a lot of evidence and information regarding embryos and newborns through this method.

There are multiple factors that determine the outcome of a pregnancy. These factors include maternal factors, pregnancy factors, prenatal care level, and more. Moreover, body mass index, maternal age, diet, toxic habits, medical problems, already existing medical conditions, all have an impact on the pregnancy outcome. The outcome strongly determines the order of the pregnancy. This is because multiple gestations amplify the risks of pregnancy issues like preterm delivery. That way, there might be a chance of a singleton pregnancy to go wrong.

What Is Singleton PregnancyDuring recent times, singleton pregnancy has sufficiently decreased. This is mostly because there is a delay in childbearing. That is why, women with more reproductive age are more likely to have multiple eggs, and so lesser singleton pregnancies occur. Ovarian hyperstimulation also plays an important role in the decrease in this kind of pregnancy. It induces the simultaneous ovulation of certain eggs. Moreover, some believe that the transfer of multiple embryos during In Vitro Fertilization or IVF plays an important role in this.

How Can Singleton Pregnancy in IVF Contribute to Safer Outcome?

We can say that IVF decreases the chances of a singleton normal pregnancy. A singleton pregnancy is more likely to be safer than multiple pregnancies. It is because the latter increases the risk of adverse perinatal results. It becomes less optimal when there is a transfer of a single embryo. Therefore, we can say if experts keep in consideration the transferral of only one embryo in IVF, the outcome can be safe. It is because a singleton pregnancy comes with lesser chances of adverse antenatal risks in the end.

Possible Complications with Singleton Pregnancy

ART – Assisted Reproductive Technology is getting popular in all types of pregnancies including singleton pregnancies. This technique is responsible for some multiple pregnancies. However, it includes high order multiple pregnancies. These processes might be leading to twins, whereas most other pregnancies lead to other processes.

Singleton pregnancy does not so often place a mother and fetus at risk. However, medical conditions prevailing like gestational diabetes, thrombosis, hypertensive complications, and other conditions increase the need for operative delivery. For normal delivery, it takes 40 weeks for the baby to develop for delivery. On the other side, the span shortens down to 37 weeks and 32 to 34 weeks for twins and triplets respectively. Preterm delivery increases the risk of the baby’s death. It can also cause conditions like cerebrovascular disease, infections, necrotizing enterocolitis, and even retinopathy. That can lead to consequences that go long term in the corresponding time. As a consequence, the price in association with it also gets high.

Ovarian Hyperstimulation – An Important Thing to Consider

There are certain applications one can apply when the ovarian hyperstimulation is taking place for alleviating different risks. These risks evolve multiple gestations. However, there are better tools and equipment for use in conditions for these pregnancies. Some important examples include In Vitro Fertilization techniques.

There are also applications for different measures that take place for ovarian hyperstimulation. These goals are for minimizing the risks of getting multiple pregnancies. IVF in this regard is safer to use. Transferring a single embryo at a time lowers this risk and singleton pregnancy occurs that way. Many statistical data and reports have put better data on the front line. These suggest that singleton pregnancy is coming with risks of different sorts on its combination with IN VITRO Fertilization. However, the singleton pregnancy that takes place naturally has much lesser risks when in comparison to the former.

What Is Singleton PregnancyRole of Technology in the Outcome of Pregnancy

Technology has identified the consequences of both ways. Stimulation has a direct effect on implantation and placentation. Stimulation is a consequence of both of these as it affects the mass accumulation in the endometrium. This can lead to an influence on the developing embryo which will later convert to the fetus. This can cause some complications in the matter. For example, it can lead to operational delivery at the time of the birth of the baby. The mother could be at risk of some medical condition. Hence, the process has some different complications with it.

What Are the Possible Consequences of the Advancements?

Iatrogenic and preterm deliveries are possible consequences of these effects that can come from certain advancements. In addition, there are certain maternal factors that can obviously have a greater risk of all kinds of pregnancies.


There is moderate research on singleton pregnancy. However, the information coming out from the singleton pregnancy can help us see the complications occurring in multiple pregnancies. With more research that contrasts and compares all possibilities, it can help females. In most cases, women get a singleton pregnancy and it appears to be normal. The important factor here is to keep in mind the impacts of unnatural methods of reproduction that can hinder this. Therefore, before seeing the type of pregnancy, the method through which pregnancy takes place also plays a significant role.
