Embryo Freezing

The terms egg freezing with embryo freezing are always confused with each other. To summarize, the egg refers to the egg cells collected from the mother, and the embryo refers to the fertilized egg with the sperm of the father. Therefore, the two freezing processes are completely different from each other as both the reasons for freezing and the processes.

Since the first pregnancy of frozen embryos in 1984, the embryo freezing techniques can be used more than 30 years. If we examine embriyo freezing in the medical language, the chemical called cryoprotectant is frozen and the embryos are stored in liquid tanks containing nitrogen and -196 degrees in compartments dedicated to the individual. Because the tank contains nitrogen, it prevents the embryos from entering into any reaction and cellular activity, it is preserved for many years without deteriorating its structure.

Why Is Embryo Freezing Done?

After the IVF treatments performed, couples want to keep their remaining embryos by freezing embryos after embryo transfer, in case they want to guarantee themselves as well as in case they want to have a sibling in the future. In particular, in the absence of reproductive cells in the couple, such as egg donation, sperm donation, embryo donation, in the treatment where the reproductive cells are taken from the outside, couples want to have siblings for their babies with the 100% same DNA.

In this way, especially maternal candidates, with age over 35, without risking the exhaustion of their eggs or the deterioration of their quality, can safely secure their next baby. In addition, mothers who are afraid of being re-treated or being injected may opt for embryo freezing to avoid this whole process of treatment.

In order to have a baby, couples who have started to be in vitro fertilization treatment and have experienced the embryo formation process through the use of various drugs will not need to live in preparation stage for the next pregnancy requests and therefore drug use. In addition, the couples will gain much more advantage in the material section, one of the most challenging aspects. Therefore, it is in their own interest that couples who are receiving IVF treatment and who are left with high quality embryos after the transfer process should perform embryo freezing.

If we look in detail at who is performing an embryo freezing after the Cyprus IVF treatment process:

  • After the IVF treatment, in the following years, those who want to have siblings for their babies,
  • Especially for the treatment for the next baby, who want to have siblings with the babies they have with 100% same DNA (especially in the treatment of the egg donation, we use fresh eggs, so the same donor may not give eggs in the future. Or similarly, the sperm taken from the sperm bank may not remain in the stocks of the sperm bank in the future.)
  • Couples who do not want to experience the same treatment costs in the unlikely event of a negative result, or in the unlikely event of a miscarriage during pregnancy,
  • Chemotherapy is a cancer treatment that uses drugs to stop the growth of cancer cells with egg or sperm cells to, so for the couples facing with these treatments, should consider embryo freezing.
  • Those who do not want to undergo the IVF treatment process again or are afraid of needles and treatment

For the reasons mentioned above, embryo freezing is performed today.

Transfer Of Frozen Embryos

When couples want to have a baby with their frozen embryos, the following steps take place:

  1. On the 2nd day of her period, the mother starts taking medicines in the form of tablets to prepere her endometrium. Folic acid supplements are provided to the mother for vitamin supplementation during the treatment process.
  2. At the end of the first 7 days of the medication, an ultrasound examination will be required to look at the wall of the uterus. According to the endometirium size, medication doses are regulated.
  3. About 12th day of medications, the ultrasound measurement is requested again and the other medicines that prepare the mother for pregnancy are started.
  4. The average of medication use is 16-18 days. On the other hand, the mother is invited to the Cyprus Miracle IVF by Dr. Firdevs and the transfer of the embriyos are carried out.
  5. Mother will be needed in Cyprus only for embriyo transfer day, which is only 1 day.

After the scientific studies on this subject, it has been proven that the embryos that have been frozen are likely to develop pregnancy even as a result of a time-out of 10 to 15 years. However, according to the directorship specified by the Cyprus Ministry of Health, embryos frozen can only be stored in liquid nitrogen for 5 years.



Egg Freezing

Because women are as effective in the business world as men, marriages and pregnancy plans can be delayed accordingly. This reduces the rate of fertility in women, especially in the opposite proportion to the mother's age. Especially after the age of 35, rapid decline in reproductive cells, women can leave in difficult situation.

Due to late-planned marriages, delayed pregnancies due to Career Planning, mandatory treatments, severe illnesses that need to be dealt with, women can lose their fertility without having any more children. In particular, women who have to undergo chemotherapy and radiotherapy will lose their eggs after the treatment, so they want to guarantee their fertility by freezing eggs.

Who Should Make The Egg Freezing Process?

  • Those who have not been married or have not made a child's plan, even though they exceed 35 years of age,
  • Those who have to postpone the pregnancy due to their career plans,
  • Those who has to go through Chemo or other radiation therapies,
  • Those who has to go through surgical operations related with ovaries etc.

Egg Freezing Process

The process of egg freezing is proceeding like a IVF treatment. The only difference is that after the egg collection process, it passes directly to the freezing process without fertilization.

Step by step;

  • On the 2nd or 3rd day of the menstural period, injection treatment is started to develop the woman's follicules. This developmen process can be carried out in the country or city where the woman is lives,
  • After about 10 days of this injections, follicules get ready to hatch with last injection,
  • After the last injection, after 35-36 hours, the woman's eggs are collected under anesthesia, within a very short period of time.
  • Mature eggs are extracted from the collected eggs and freezing is performed.

For this procedure, only 1 day in Cyprus is enough.
