Embryo transfer

mother-surrogate.infoA few days after the donor oocytes are fertilized by your partner’s or donor sperm, you will come to our laboratory for the embryo transfer. Transfer is a simple and painless technique but some patients require anesthesia to relax their muscles. On the same day the embryologist will give you information about the quality of embryos to be transferred. The proceedure is very similar to that of intrauterine insemination. You have to drink approximately 1 lt of water before the transfer, as a full bladder allows the Doctor to identify the uterus using a transabdominal ultrasound more easily, it straigthens out the cervix and allows the transfer to go more smoothly.

Risk and side effects:

Any possible risks are discussed fully with you and your partner before the whole procedure. The physical effects of blood testing and hormone therapy are minimal. The intramuscular injections may be painful and if you have highly sensitive skin you may have some minor reactions at the injection sites. Also the transfer may carry the risk of cramping and bleeding.

Succes rates:

mother-surrogate.infoOur success rates are very high related to a combination of high quality oocytes and the expertise of our team of highly experienced physicians, nurses, embryologists and other laboratory staff. Our chances for success are significant but there is no quarantee regarding the outcome since the pregnancy is affected by factors that differ in every case. You and your partner may face clinical problems that prevent fertilization or the donor’s cycle may be effected because of stimulation problems. This may decrease the number of the oocytes retrieved from the donor or affect the quality of the embryos in a negative way. Another risk factor is multiple pregnacy but we take precautions to minimise this by decreasing the number of embryos transferred.

Cryppreservation and disposition of embryos:

At the end of the cycle, you may end up with more embryos than needed for transfer. If those remaining embryos are of a high enough quality, they will be frozen. Approximately 50% of our donor cycles have extra embryos for freezing. Embryo freezing will allow you to undergo a subsequent transfer without stimulation.
