Embryo transfer


The couple will be informed on the day prior to the embryo transfer of when, how and where the procedure will take place.

In most cases, this method is very simple. The transfer is made via the vagina with ultrasound guidance. No anaesthesia is necessary. In special cases, ultrasound-guided transmyometrial transfer may be conducted, under anaesthesia.

Embryo transfer may be conducted 2-3 days after the follicular puncture (D+2 or D+3) at the 4-8 cell stage or after 5-6 days at the blastocyst stage (D+5 or D+6). The number of embryos and the day of transfer are determined by the quality of the embryos and the woman’s age. Other factors may also be considered such as the cause of the infertility, medical history, previous pregnancies, etc.

Before the transfer, the embryologist will evaluate the embryos and select those with the best prognosis. The selected embryos are transferred together with a small quantity of the culture medium via a transfer catheter.

The patient adopts the lithotomic position and the gynaecologist gently introduces the probe into the cervix and deposits the embryos inside. This process does not require anaesthesia and is conducted via the vagina under ultrasound guidance. It lasts only a few minutes, but the patient should remain in absolute rest for 15 minutes.

Under no circumstance shall more than three embryos be transferred per cycle. A discussion between the doctor, biology team and the couple should be held before deciding how many embryos to transfer. When there are surplus embryos not used in the cycle, any embryos that develop favourably may be frozen provided the couple have granted their consent.

Discharge and life-style post-embryo transfer

On the day of the procedure, it is advisable to rest for at least 4 hours after leaving the clinic. If not resident in Barcelona, you may travel home after this time or on the following day using the method of transport of your choice.

Following the transfer, you should continue the hormonal treatment prescribed by the gynaecologist in order to ensure that the endometrium is properly prepared to receive the implant.

Your lifestyle after the embryo transfer should be calm, avoiding extreme physical exertion, sports, hip baths and sexual relations until the first pregnancy test has been conducted.
