What is “the Transfer day”

Embryo transfer is a procedure in which a thin catheter is passed through your cervix and one or two embryos from your IVF or ICSI therapy are placed into your uterus to enable for implantation.

What is “the Transfer day”

We’ll have chosen the highest-quality embryo(s) with the best probability of resulting in a healthy pregnancy. If any excellent quality embryos remain, we will store them so that you can use them in the future if desired.

We will discuss the following topics with you during your fertility therapy and before we do your embryo transfer:

Is it safe to transfer after an extended embryo culture on Day 5?

Would you benefit from an elective embryo transfer (eSET)?

Every situation is unique. As a result, we will tailor our approach to your unique circumstances in order to make the best decision possible for your embryo transfer. We are dedicated to giving you the best opportunity of conceiving a child.

Is it better to transfer on Day 3 or Day 5?

  • We strive to cultivate embryos for longer periods of time and transfer them on Day 5 whenever possible in our lab. The following are the key reasons:
  • It is safe to maintain embryos in culture for that long. To allow blastocyst formation, currently existing embryo culture techniques are well established and imitate the natural environment.
  • More information regarding the development can be found under extended culture. We can identify embryos that, although being of good quality on Day 3, do not develop properly or are arrested later. As a result, we may be able to improve embryo selection and increase live rates per embryo transfer. Our success rates can be found here.
  • Because they have experienced critical gene activation, cell specialisation, and differentiation, embryos that grow into blastocysts on Day 5 are more likely to result in a pregnancy.
  • The embryo would normally enter the uterus on day 5 of the pregnancy. The embryo must be in the blastocyst stage to be implanted.
  • It’s vital to remember that not all embryos will develop into blastocysts. Approximately 30-50 percent of embryos will make it to this stage of development. As a result, an extended culture and transfer on Day 5 may not be appropriate for everyone.
  • If your IVF or ICSI cycle produced a small number of embryos, it’s possible that only a few or none will make it to Day 5, in which case we’ll explore a Day 3 transfer. During your treatment cycle, we will always address this with you.

Single Embryo Transfer is an optional procedure (eSET)

When there are numerous good quality embryos available for transfer in an IVF or ICSI cycle, an elective single embryo transfer (eSET) is performed. Don’t worry, eSETs don’t lower your chances of success. The goal is to increase the chances of a pregnancy while lowering the possibilities of multiple pregnancies.

You should keep in mind that even if we only transfer one embryo, there is a slight chance of multiple pregnancy. This is due to the extremely uncommon probability of the embryo dividing into twins. A single embryo transfer carries a 1-2 percent risk of multiple pregnancies, according to the HFEA.

Although the prospect of a twin pregnancy may seem appealing, it’s important to consider the risks to the developing children (miscarriage, prematurity, birth defects, and so on), as well as the risks to yourself (high blood pressure, gestational diabetes, anaemia, and so on) and the long-term effects on you and your family.

We are serious about our goal of reducing unwanted multiple births. With this in mind, we carefully consider whether one (eSET) or two embryos should be transferred. Your age, treatment history, and the quality of your embryos or blastocysts will be used to calculate this. At the time of your embryo transfer, we’ll always let you know what we think is the best plan for you. Please do not hesitate to contact us if you have any questions.

Transfer of Frozen Embryos

  • A frozen embryo transfer is only possible in a few circumstances.
  • If you chose to take our optional course, Option to Freeze All Embryos
  • If you had leftover embryos from a prior fresh IVF/ICSI round, you can use them in this cycle.
  • If you have your embryos frozen for medical reasons or to preserve your fertility.
  • We can defrost them one at a time and insert them in your uterus like we would in a new cycle to try to develop a pregnancy in each case.

What can I expect?

  • We recommend that you bring a companion or a friend with you since we prefer that you have someone with you and someone to drive you home after the treatment. Please be informed that owing to Covid-19, there may be certain restrictions in place. If this is the case, please double-check before transferring.
  • We’ll let you know how many embryos we’ll be transferring and how good they’ll be. Prior to the embryo transfer, we will ask you to sign the consent form. You can also choose to see the embryos on a screen before we transfer them if you like.
  • The catheter carrying the embryo(s) to be transferred will then be brought to you by one of our embryologists. Using an ultrasound to guide him/her, our specialist fertility consultant will insert the catheter through your cervix and deposit the embryo(s) at the fundus of the uterus.
  • Finally, the embryologist will return the catheter to the lab to ensure that it is clean, indicating that the embryo(s) have been successfully implanted into your uterus and that the catheter is empty. The procedure will be repeated if any embryos are discovered on the catheter.

After that, what should be done ?

After the transfer, you do not need to rest. Lying on your back for days following will not help the embryo(s) implant and may really hurt you. We urge that you take it easy and avoid hard activity or horseback riding, but otherwise try to carry on with your life as usual.

Your pregnancy test can be scheduled on the date set by your consultant. 15 days following your transfer, this is normally completed.
