You may have come across various double embryo transfer success stories in the news wherein a woman gives birth to multiple babies. Recently, a news article featured a story of a couple conceiving 9 children at a time, and all of them survived with healthy body weight. Well, modern technology and science have enabled intended parents to consider conceiving multiple children in one attempt but couples and surrogate mother considering gestational surrogacy do not need to worry about this. The surrogate mother won’t have to bear 9 embryos in her womb, IVF specialists do not permit intended parents to choose multiple or double embryo transfer without a screening process.

What are the chances of unplanned and sudden multiple surrogacy pregnancies? What is the double embryo transfer success rate? We will be discussing this further in detail,, but as In- vitro fertilization (IVF) has improved over the years, intended parents won’t experience the sudden shock of conceiving multiple surrogacy babies.

Over the years, scientists and doctors have improvised the IVF treatment, so the procedure won’t have only one embryo implanted but clinicians would recommend multiple embryo transfers only when intended parents are expecting twins.

While conceiving triplets, twins, or quadruplets through surrogacy is safe unless you take precautions and consult top fertility specialists. Furthermore, there is also another alternative that isn’t quite common yet, a single transfer can also produce identical twins as a single embryo can split. Although the chances of SET (single embryo transfer) are rare, the surrogacy split of SET is 0.95%, whereas in natural pregnancy it is 0.45%.

Why should one consider transferring only a single embryo?

As you must be aware of the IVF program procedure, the gamete material of the Intended parents and or donor is mixed in a laboratory to create embryos. Once embryos are healthy and in good condition, it is further transferred to the surrogate’s womb.

Now, the number of embryos to be transferred differs, while intended parents usually assume that in order to increase the chances of a successful pregnancy, they must choose to implant multiple embryos.

Well, if intended parents are pretty sure they want a single child and not twins then transferring one embryo is appropriate. Having more isn’t always beneficial, implanting more than one embryo may result in multiple babies.

Multiple or double embryo transfer

The number of embryos to be transferred comes down to the laws regarding IVF treatment in a particular country you apply for multiple embryos and on intended parents, for whether they wish to conceive twins or triplets in one go.

Usually, intended parents ask to perform at least 2-3 embryos at a time, to save time from facing failure in confirming pregnancy and also to cut the cost of repeating the IVF procedure again. You don’t need to worry, our expert and IVF specialist are there to help you choose the right path that is best suited and safe for you.

Before you commence with IVF treatment, intended parents must determine if they are okay to conceive twins and take responsibility for multiple babies. There is no harm in choosing double embryos transfer, you still can conceive healthy children but every medical process has some risk factors, which we will discuss further in detail. You must have the consent of your surrogate mother to carry multiple babies as well.

How many embryos must be transferred?

As we discussed earlier, factors determining the number of embryos to be transferred are the laws regarding IVF treatment, intended parents willing to conceive twins and recommendation of fertility experts.

Singleton or double embryo transfer, both have their pros and cons. Although you can choose to perform multiple embryo transfers, there are a few risks that the intended parents and the surrogate mother must be aware of before beginning the process.

  • The risk of having a baby with lower body weight i.e less than 5.5 pounds increases to 9% when a woman carries a single child, whereas double embryo transfer twin rates rises to 57% and 96% with triplets or multiple babies.
  • Preterm baby ( born within 37 weeks) is one of the most common conditions in twin newborn twins, double embryo transfer twin rate is around 65% and in triplets, it is around 97%. Whereas with a single baby the risk of preterm birth is only around 14%.
  • The pre-eclampsia risk (pregnancy-induced hypertension) is 3 times higher in surrogate mothers who carry multiple babies.
These risks are common with a single newborn child as well. What should intended parents do if they still want twins via surrogacy? Through precaution, one must take care of their surrogate mother and babies via proper medication.

Consult a renowned surrogacy agency like Global Star Surrogacy and a top fertility clinic that ensures to perform detailed analysis and provide thorough guidance to intended parents.

Perks of choosing for double embryo transfer

We have discussed every factor that leads to double embryo transfer success rate, let’s understand what are the benefits it has to offer to intended parents. While it is safe and probable to conceive multiple children via surrogacy, it surely has some amazing advantages, which include:

Both parents can have a genetic link with their twins

Usually, the gay couple faces massive issues with providing a genetic link. Either one of the partners could only provide their gamete material but with double embryos, both of the partners can provide their sperm sample and it can further be mixed with the same or different egg donor to form multiple embryos. WIthin gay couples, we have witnessed various double embryo transfer success stories to date. Furthermore, it is transferred into the surrogate mother’s womb. Once she confirms her pregnancy, you just need to wait for your little versions of you to arrive!

Saves the intended parent’s time and effort

The overall surrogacy procedure is quite time-consuming and daunting. Intended parents need to be patient, the process is not only about forming embryos but it consumes time as finding a surrogate mother and donors may take quite a while. Also, they need to undergo a screening test, hence the shortlisting procedure may seem like forever to you.

Repeating this entire process may test your patience and efforts, hence a lot of intended parents choose to conceive twins via surrogacy, with seeing the double embryo transfer success rate.

Why do intended parents prefer having double embryo transfer?

There could be thousands of reasons one could choose multiple surrogacy pregnancies i.e choosing multiple embryos implantation over singleton pregnancy through surrogacy, one could get influenced by listening to various double embryo transfer success stories as well. Well, multiple births may give an option to intended parents and surrogate mothers or prevent them to undergo the entire surrogacy procedure again. It is like investing all your money, time, and effort in everything at once.

One of the major reasons is cost, not all intended parents have that much money to try the surrogacy method again in the future. As we know surrogacy isn’t inexpensive or free, in terms of surrogacy overseas the cost increases.

In the case of multiple surrogacy pregnancies, it saves intended parents money by reducing the cost of fertility treatments, travelling costs, and surrogate or donor’s compensation in the near future. The reasons can be personal or emotional for each intended parent, as they do not want to miss out on a single opportunity of creating a new life after facing a few failed attempts with other fertility treatments.

When does someone choose double embryo transfer?

In surrogacy, multiple births result when more than one embryo is implanted into the surrogate’s womb. Although, like many intended parents, fear that multiple implanted embryos will guarantee multiple fetuses into the womb of a surrogate, gives an opportunity to conceive more than one child at a time.

Usually, when one fertilized egg splits into various embryos, identical twins or triplets are delivered. Twins have a 1.2% risk of being born from natural pregnancy, whereas triplets have a 0.013% chance of being conceived through natural pregnancy.

However, identical twins or triplets with surrogacy aren’t uncommon, one can conceive twins by using gestational surrogacy. If the intended parents are sure that they want identical twins together, hence multiple embryos are transferred.

When you begin with IVF treatment, usually fertility clinics ensure that they incubate or store eggs prior to the implantation phase so the eggs can develop normally.

What are the essential factors for multiple or double embryo transfer?

First, let’s understand what does transferring a double embryo mean? Identical twins are born when more than one embryos are present in a woman’s womb .Yes, intended parents can conceive multiple babies through surrogacy. Although there are a few factors that determine double embryo transfer success rate and every IPs must be aware of them.


You can fulfill your wish of conceiving twins but you must consider that the cost of surrogacy will increase as the surrogate mother goes through a few health risks and hence will ask for more surrogacy compensation. Also, raising two or more kids together can be difficult and financially challenging as you will need multiple items for your child on a daily basis. But, the moment you see your little munchkin, it is worth giving it a shot!

Surrogate Match

Intended parents who choose to transfer a single embryo are more likely to get a surrogate match faster as surrogate mothers are well familiar with the process and risk factors of carrying multiple kids.

Even if she agrees to carry your twins or triplets, seeing the double embryo transfer twin rate, not every surrogate mother is approved to carry forward with the surrogacy procedure. Physicians will perform certain tests to determine whether she can carry multiple kids and if she is fit and fertile.

Having a surrogate mother, who has experience with carrying twins and is absolutely fit physically and emotionally, you can be relaxed and wait for your child to arrive. At Global Star Surrogacy we ensure there is no hindrance kept between intended parents and surrogate mother.

Health and safety precautions for your children

Although medical science and technology have enabled intended parents to fulfill their impossible dreams with amazing double embryo transfer twin rate, there are few health risks with multiple surrogacy pregnancies. Although, the majority of the health risks are associated with the carrier i.e intended mother or surrogate mother, at times fetuses may be at risk specifically after the delivery. Some of the health conditions with surrogacy newborns include:

  • Low birth weight of the baby
  • Placenta abruption
  • Preterm delivery
Though the chances of getting these issues are very rare, as additional check-ups are scheduled with the obstetrician, and every movement or process of fetus development is monitored. In case of any uncertainty, doctors will educate the intended parents and surrogate mother about precautions, and medications to overcome health risks with the child.

Health and safety measures for your surrogate mother

Taking care of a surrogate mother’s health is our priority. Before an intended parent finds an accurate surrogate match, she needs to undergo a thorough physical as well as psychological screening test to check if she is fit and fertile to physically carry your child. And, surrogacy as a journey can be overwhelming for a gestational carrier, hence determining her emotional awareness of the process is a must.

A surrogate mother who can carry your child successfully is evaluated, although there are always minor chances for complications and with twin surrogacy, surrogate mother can face few health risk, includes:

  • Pre-eclampsia
  • Preterm labor
  • Gestational diabetes
  • Cesarean section
Usually, surrogate mothers are aware of the consequences of multiple embryo transfers leading to surrogacy. Although, all the parties i.e intended parents and the surrogate mother must have an agreement before performing embryo implantation.

Selective reduction

When a surrogate mother carries multiple babies i.e more than twins, usually physicians would recommend performing selective reduction. Well, what is selective reduction? It is a process wherein fetuses are reduced to 1 or 2 from carrying multiple fetuses.

Why is this process essential to perform? In multiple surrogacy pregnancies i.e carrying triplets or more, the risk can increase so in order to have a successful full-term pregnancy and delivery of healthy children, this process is recommended by doctors.

Concluding words

Multiple or double embryo transfer is absolutely safe, although there are a few risks, but doing your own research is a must, approach a trustable agency to experience a hassle-free surrogacy program.
