EMBRYO TRANSFER: The number of embryos transferred

The embryos obtained after in vitro fertilization can be transferred into the patient's uterus at all stages, but most often this transfer takes place two days after the contact of the male and female gametes.

Single embryo transfer-

The number of embryos to be transferred into the patient's uterus is decided after discussion between the medical team and the couple.

Most often, an embryo is transferred in order to avoid multiple pregnancies, but it also happens that two, three, or even exceptionally three embryos are transferred.

Multiple embryo transfer-

The number of embryos transferred is decided mainly according to the age of the spouse, her background, the couple's desire, but also according to the morphological aspect of the embryos.
Indeed, if any embryo is able to evolve and give birth to a healthy child, some embryos are more likely to implant than others. As this probability of implantation can be assessed thanks to the appearance of the embryos under a microscope, this is an important parameter which must be taken into account on the day of transfer.

It is also possible to transfer embryos at a more advanced stage of their development to the stage called a blastocyst.

Embryo transfer success rate-

This embryonic stage is generally obtained after three days of additional culture in the laboratory.
The transfer is therefore carried out five days after the follicular puncture.

The embryo transfer is carried out using a flexible and thin catheter containing the embryos. This catheter is introduced into the uterus after placing a speculum.

When the catheter is in place, the doctor deposits the embryos by gently pressing the syringe.

The replacement of embryos is most often performed under ultrasound which allows to correctly placing the catheter and allows us to see the correct positioning of the embryos regardless of the size or position of the uterus.

When the embryos are in the uterine cavity, the catheter is then gently removed. The patient can then resume a normal life, however without too violent effort.

This transfer of embryos, a painless gesture, does not require anaesthesia or hospitalization.

Sometimes other treatments can be combined, in particular anticoagulants by subcutaneous route depending on the patient's history or associated pathologies.

A blood HCG beta test is performed from the 14th day after the puncture, to detect the onset of pregnancy. The pregnancy will then be confirmed by ultrasound four weeks after the transfer.
