The procedure is performed on an empty stomach and under general anaesthesia, which usually lasts no longer than 10 minutes.
The contents of the follicles are retrieved by a doctor during an ultrasound scan using a puncture needle. For egg retrieval, we use a very thin needle, which, with its significantly smaller tip diameter, is more gentle in penetrating the tissues and thus minimizes the risk of complications.
Embryologists then search for eggs in the follicular fluid, which are fertilized the same day and become embryos.
After retrieval, you take a nap and rest for a while. You can also have a cup of tea and a bite to eat. Just one hour after the procedure, you can go home with your escort and return to your normal activities. We do not recommend driving the day after anaesthesia.
We then freeze the eggs so they are ready for use on the day we receive the sperm from the donor.
Most frequently asked questions
When and how are eggs retrieved?
The exact retrieval date is selected by the doctor following ultrasound examinations. Ovitrelle must be applied 36 hours before the puncture. Ovitrelle is a laboratory-produced hormone that is injected into a fold of skin in the lower abdomen. No need to worry about forgetting – we’ll send you a text message to let you know when the time is right.
What regimen do I need to follow before the egg retrieval process?
Don’t smoke or eat or drink anything from midnight before the collection. Then come to our clinic on the morning of the puncture.
What are the advantages of using a thin needle?
The Kitazato needle we use for the puncture has a tip diameter of just 0.912 mm (as opposed to the 1.149 mm needle commonly used). Using this needle is safer and less painful for patients. The treatment is also more comfortable as you need less analgesics and anaesthetics. Laser treatment of the needle tip ensures safer access to the follicle and less resistance from the surrounding tissue.
