Egg transfer

After egg retrieval, the eggs are fertilised in the laboratory using the IVF or ICSI method. They are then placed in an incubator (heating cabinet) where they begin to divide.
At Aleris-Hamlet Fertility, we use the new EmbryoScope+ technique for cultivation of fertilised eggs (embryos), which helps increase your chances of getting pregnant. Read more

The day after egg retrieval

The first sign of successful fertilisation is two pronuclei, which can normally be seen 18-20 hours after fertilisation. The pronuclei contain the hereditary material from the sperm cell and from the egg. The membrane of the pronuclei is dissolved shortly afterwards, and the hereditary material from the egg and sperm cell merges. The egg now contains a complete set of chromosomes.

2, 3 or 5 days after egg retrieval

On day 2, some fertilised eggs may have divided into four cells and be completely regular, while others may have divided into two or three cells and be irregular or contain several nuclei.

The fertilised eggs are assessed in the laboratory according to a scoring system developed on the basis of the latest research. Here, it is decided which fertilised eggs are suitable either to be:

  • Transferred to the uterus on day 2 or day 3
  • Cultivated further until the blastocyst stage (day 5 or 6) and then transferred to the uterus
  • Frozen at the blastocyst stage (day 5 or 6)

What is the procedure for egg transfer?

An egg transfer to the uterus is normally a pain-free procedure lasting only a few minutes. We usually only transfer one egg. The decision on one or two eggs depends on the quality of the eggs, your age, the number of previous attempts and the cause of your childlessness.

This is done in the same way as a ordinary gynaecological examination, in which the doctor inserts a thin catheter through the cervical canal and places the egg surrounded by a bit of fluid in the uterus.

When the fertilised eggs are in the uterus, they can attach themselves to the endometrium and develop further.
