What happens in the laboratory?
Day 0 = Puncture Day:
All usable eggs are extracted from the patient’s ovaries (follicle puncture). This procedure can be carried out under a light anaesthetic or general anaesthesia (performed by an anaesthesist). The patient will be asked to empty her bladder before the procedure. The puncture is followed by the fertilisation using IVF or ICSI. In IVF eggs and sperm are concentrated in vitro. In ICSI one single sperm is inserted into the egg using a hollow needle.
Day 1 after the puncture:
Some eggs fertilise and some don’t. The fertilised eggs are recognisable because they have two pronuclei.
Day 2 after the puncture:
The fertilised egg has already developed to a two-to-four-cell group. Now we decide whether to put embryo(s) straight back into the female uterus (embryo transfer) on day 3 or 5. You will receive a phone call from the KinderWunschKlinik laboratory today to make the date for embryo transfer!
Day 3 after the puncture:
The fertilised egg may have already divided itself into an eight-cell group. Either we put it (them) into the female uterus today or we wait until day 5.
Day 4 after the puncture:
The morula-stage is reached.
Day 5 after the puncture:
The embryo(s) is (are) in the blastocyst stage and is (are) put back in the uterus today at the latest. This procedure is completely painfree similar to a gynaecological examination and requires no anaesthesia. The patient is asked to arrive at the KinderWunschKlinik with a full bladder!
