Egg extraction

Egg extraction

Egg extraction is a process by which the woman's ovules are removed from the ovaries. These eggs are then mixed with sperm to facilitate fertilization. In order to be able to extract the eggs, first the ovaries have to be stimulated by the ovaries of the woman by means of certain hormones. Once the number of follicles (potential eggs) has formed, the fertility specialist can remove these eggs from the ovaries, to try to produce fertilization. If the fertilization is successful, the embryos will be placed later in the womb of the woman.
Ovarian follicles
The ovarian follicles are small sacs filled with a fluid, located inside both ovaries.

A woman is born with millions of such follicles, each containing in its center an immature egg. Every month, due to certain hormones, multiple follicles begin to develop. The strongest follicle will attract most of the FSH (follicle stimulating hormone), a hormone secreted by the pituitary gland, causing the follicle to rupture and release the egg, while the rest of the follicle dies. This is ovulation.

Stimulating follicular development
For IVF to be very effective, more mature eggs (not just one) must be extracted. The specialist endocrinologist specializing in reproduction will try to remove all viable follicles from your ovaries so that he can fertilize more eggs. This means that the woman must have artificially stimulated follicles.
There are special medicines that you will need to take to stimulate the development of your follicles. These drugs may include:

  • Clomid
  • FSH
  • hMG.
  • These drugs can be given orally or subcutaneously for about 10 days.
    Monitoring of follicular development
    Programming is very important when it comes to the egg extraction process. If your follicles grow too much, then the egg inside will become too mature to be fertilized effectively. This can seriously affect the in vitro fertilization process.
    For this reason, your ovaries will be monitored to be able to track the development of your follicles. This is usually done with the help of ultrasound. When your follicles reach the required maturity, they can begin to extract the eggs.
    How to do it
    The process of egg extraction is relatively simple. It usually happens in the local fertilization clinic or in a hospital affiliated with this clinic. The follicles in both ovaries (right and left) will be removed by a process known as follicular aspiration. Follicular aspiration involves the insertion of a special needle through the upper part of the vagina and into the follicles. This needle is subsequently used to aspirate all the follicles present in the ovary.
    To guide the needle in the immediate vicinity of the ovaries, you will have a transvaginal ultrasound. This will allow your doctor to insert the needle into your ovaries at the right place. This procedure is performed under anesthesia, so you will not feel any pain.
    Once the needle is inserted into the correct position, the doctor will use it to aspirate all the follicles inside the ovaries. These follicles will be examined immediately under the microscope to ensure the presence of viable eggs. The follicles are then placed in the incubator.
    Depending on your age and the effectiveness of fertility drugs, between 5 and 20 eggs will be extracted during the egg extraction process. The entire process usually takes between 15 and 30 minutes.
    To remember!
    After extracting the eggs you will feel a slight tension in the abdomen. You will also feel dizzy as a result of anesthesia. After 2 hours of being monitored in the clinic, you will be allowed to leave home. You may notice a slight vaginal discharge colored in red or brown. This is normal and you should not worry. You will also receive antibiotics from your doctor, who will prescribe you to prevent any infection.
    Next step after egg extraction
    After egg extraction, all viable eggs will be mixed with a sample of sperm from a partner or donor. These eggs will then be grown overnight until they are checked for fertilization. If they have been fertilized, the next stage of IVF treatment can begin: embryo transfer.
