After oocyte retrieval, the embryos are grown in the laboratory. During the fifth day of the embryos’ lives (blastocyst stage) or during the third day, they are transferred to the uterus.

The embryo transfer is a simple but delicate procedure.

Simple because the gynecologist will pass a catheter gently through the cervix into the uterus. After that, the embryologist will pass the embryos through a thinner catheter. Then, he will deposit the embryos into the uterine cavity while ultrasound monitoring. It isn’t a difficult process and it lasts only a while. This procedure usually does not require anesthesia. Then we regularly add Embryoglue.

Delicate, because with a sudden move by the gynecologist, the embryologist or the patient may block the smooth transfer.

The gynecologist’s experience and his ability to communicate with the embryologist, the midwife and the patient play an important role.
