Egg freezing, also known as oocyte freezing or oocyte cryopreservation, can be defined as the freezing and storage of a woman's eggs so that they can be used in the future and thus preserve her fertility in the future.
Egg freezing, which has been widely mentioned in recent years and discussed both in the media and among friends, can be performed meticulously by us as in many clinics.
Oocyte freezing, which has been reported by the American Society for Reproductive Medicine (ASRM) as a method that can be routinely applied, is a method that can be applied by women who are currently unable or at risk of becoming pregnant or who want to become a mother in the future.
Another beneficial aspect of egg freezing is that it preserves the biological structure of the egg cell at the time of the procedure, as well as preserving the ability of women to become mothers.
Immunization treatment is started on the 2nd or 3rd day of menstruation. Up to 2 eggs are allowed to grow in the vaccination treatment. At certain intervals, the diameter of the follicles is examined by vaginal ultrasonography. After the follicles reach a certain level, an egg hatching injection is given. 35-36 hours after the egg hatching injection, the sperms taken from the man are prepared by passing through certain stages, that is, sperm washing is performed. The motile spermatozoa are selected and then injected into the uterus with the help of a thin cannula. The patient has no pain during these stages and it does not affect their daily life. After resting for an average of 20-30 minutes, the patient resumes his/her normal life.
In egg freezing, the process starts with the examinations performed on the person who wants to freeze her eggs after the patient is evaluated. First of all, the egg reserve is evaluated by ultrasound, if there are any unwanted masses such as cysts or fibroids, they are evaluated. A gynecological examination is performed to assess the presence of infection. Necessary vaginal smear and culture samples are taken and sent to the laboratory. On the second or third day of menstruation, blood tests are taken from the person whose eggs will be frozen and sent to the laboratory. If there is no underlying condition that needs to be treated and all conditions are suitable, the patient is given hormone medication on the 2nd or 3rd day of her menstruation and treatment is started. The drugs used in this treatment are in the form of injections, and the method of use and description of the drugs are given by our training nurse.
Since egg freezing is based on the collection of a large number of eggs, hormone drugs are used for this purpose. For this purpose, it is necessary in the first step to enlarge the existing egg clusters by means of injections.
This process consists of an injection and ultrasound examinations lasting about 7-10 days. The aim of these medications, as we have already mentioned, is to ensure the development of a large number of mature eggs. Antagonist medication is added to the patient to prevent the mature egg(s) from hatching. The patient is closely monitored during this process, which continues for approximately 7-10 days.
Then, for the final maturity of the eggs that have reached the required number and size, a hatching injection is performed and the eggs are collected 34-36 hours later. Egg collection is performed while the patient is asleep under anesthesia. It takes about 10-15 minutes. The patient is discharged after an hour of rest.
On the day of the procedure, the patient is advised not to drive or go to work as he/she is under anesthesia. The next day, he/she can return to his/her normal routine. One hour after the procedure, she can start eating and drinking normally. One day after the procedure and 3 days after the procedure, the patient is informed about the number and quality of the eggs to be frozen. Every year, the patient is contacted about whether the freezing period of the frozen eggs will be extended or not.
Just like in IVF treatment, the most important factors affecting the success of egg freezing are the woman's age and egg reserve. The younger the woman's age during the procedure, the more eggs will be collected and the better the quality will be.
While married couples usually undergo IVF treatment, a single woman who wants to become a mother in the future can resort to egg freezing.
Generally, it is preferable to access the uterus and the eggs to be collected vaginally for the examination to be performed as part of the egg freezing procedure because this way is much easier and does not cause problems.
A virgin woman may refuse to undergo a procedure for egg freezing that is likely to lead to hymen disruption. In such cases, the procedure can be carried out by abdominal ultrasound and egg retrieval, but it should be recognized that this compulsory method is more difficult and potentially problematic.
If the chastity membrane is flexible, egg freezing by vaginal route may not damage the chastity membrane. However, the patient should be informed about all risks before the procedure.
