Perhaps this is the most exciting time in each In vitro procedure – the time when so many wonderful emotions, so much faith and hope come together in one very special moment for the couples. After this procedure comes the time of the great anticipation till the time of the test, and then ... Then we wholeheartedly wish you to reach the happiest and most exciting months of awaiting and giving birth to your newborn baby ... It is the moment when we all pray together with you.

The embryo transfer is a procedure of inserting the embryos into the uterine cavity. It is carried out about two to five days after the puncture of the follicles - the time necessary for the egg fertilization to occur and the embryo development to be performed in laboratory conditions.

It is important to know that: If the embryo goes through a normal stage of development and reaches a stage with two to eight cells after several consecutive intervals (usually after 48 hours), then the cells are transferred to the uterus. Sometimes the transfer can be performed on the 4th - 5th day after the puncture, when the embryos have already reached their blastocyst stage.


This stage seems to be the simplest one in the whole range of assisted reproduction techniques but is one of the most important ones.

What is embryotransfer?

The embryo is placed in a very thin tube under microscopic control. You will be lying in the same position as for a regular gynecological examination. Using a speculum, the gynecologist reaches your cervix and gently introduces the cannula with the embryo in your uterus.

One to three embryos can be transferred at the same time.

The gynecologist inserts the embryo in your uterus and removes the tube. The procedure is absolutely painless and it feels similar to the one in a smear procedure.

When you have more fertilized eggs, the finest of them are transferred into your uterus, and the rest of the eggs can be frozen or destroyed. That depends namely on the preferences of you and your partner and the potential of the medical team to perform the procedure.

If you and your partner have decided to have the remaining embryos frozen, please remember to fill in a contract for freezing of ova/embryos. You can obtain the form from sector 5, next to the cashier desk, as soon as the embryologists have informed you that the freezing has been really completed.

IMPORTANT: Your chances of a pregnancy to occur are higher when more embryos are transferred, and the better quality they are, the more you increase your chances for success. On the other hand, the more embryos are transferred and the "nicer" they are, the greater the probability of multiple pregnancy.

This fact poses a risk on the development of the pregnancy, on the babies (premature births are four times more common) and on the status of the pregnant woman- including sometimes on her life.

This is the reason why the medical team, when performing an embryo transfer, is trying to find the balance between raising the chances of the implantation, on the one hand, and limiting the probability of multiple pregnancies, on the other hand, at least a twin pregnancy (5-8% of all cases).

The question how many embryos will be transferred you have to discuss with your obstetrician/gynecologist.

Before the embryo transfer:

You will be informed by our embryologists when your transfer will be and you will be given detailed instructions on how you should prepare for the transfer.

  • Unlike the puncture, the transfer does not require that you follow a preparation in advance (related to food and fluids), by contrast, you should have a good rest before coming to the hospital, be relaxed and have had enough food.
  • You have to start drinking liquids (about half-a liter of water) half an hour before the procedure. Your bladder should be full.
  • If you have an appointment for acupuncture (you will be offered to have it on the day of the transfer), you will be directed to the specialized room (manipulation room) on the first floor, where the procedure takes a few minutes.
  • By "rule", prior to the transfer, you are given medications (pre-medications), in the form of intramuscular injection, which has a calming and muscle-relaxing effect. The relaxed condition of the patient at this point is very important in order the passage of the tube through the cervix to be facilitated, and any uterine contractions to be prevented, which otherwise may affect the embryo and move it to a wrong place in the uterus.

During the transfer:

Transfers are performed by an obstetrician-gynecologist in specialized hospital units (manipulation rooms), located in the in vitro section on the first floor (the same rooms where the puncture procedures are performed).

  • After being called for the transfer you will have to leave your clothes and personal belongings in the locker. You will be provided with a gown, a hat and socks disposable.
  • Your physician and obstetrician will be with you in the manipulation room, and the embryologist will be waiting in the next room, in a special "embryobox"; the embryologist will have prepared your embryos for the procedure beforehand.
  • the manipulation itself causes no pain, so anaesthetic is not necessary. The only discomfort that you may feel is caused by your full bladder and the additional pressure caused with the ultrasonographic device.
  • you will be informed if there are quality embryos that could be frozen.

What follows next?

You will receive an Embryo-report of the procedure and something else ... after the transfer you will leave the facility with pictures of the embryos that have been transferred and are already in you ... and you will be filled with anticipation.

When the procedure is completed, you will stay to rest on the gynecological chair for about 20 minutes in the company of good music.
These are your moments of relaxation after a whole series of injections, manipulations and emotions through which you have gone in these few weeks of the adventure called "In vitro".

After the transfer your physician will prescribe you the necessary medications for intake till the time for your test and will advise you what you should do till the time for your test.

Our recommendations until the day of the test

  • Be positive, surround yourself with positive emotions, walk, read a good book, watch romantic movies and films with a happy end.
  • Reduce your physical activity,this does not mean to lie constantly.
  • Avoid stress as running, gymnastics, swimming, gym, lifting heavy objects.
  • Limit your intake of coffee and chocolate, give up energy drinks and alcohol. Cut on cigarettes.
  • Do not take long hot showers, forget about sunbathing, swimming pools, sauna and solarium.
  • Beware of diseases, even mild cold can be fatal for your embryos.
  • Do not forget the person next to you, be close to each other and support each other in the two long weeks of waiting, that are to come.

If you have severe abdominal pain, excessive bleeding, dizziness, vomiting and other unusual and disturbing symptoms, please contact your physician promptly at the emergency phone line or come to the hospital so that we can consider on time what actions to take.
