Embryo Freezing Process
The process of taking the male and female reproductive cells from the body and combining them and placing the healthy embryos in the uterus of the mother is called in vitro fertilization treatment. In vitro fertilization treatment is a great source of hope for couples who have not been able to have a baby naturally for many years, and who cannot achieve pregnancy despite intrauterine insemination and ovulation treatments. Because women with low egg reserve, anomalies in the cervix and inside, clogged tubes, and men whose sperm quality and number are not sufficient for pregnancy can have a baby with in vitro fertilization treatment (Embryo Freezing Process).
Considering today’s medical technology and the point reached in infertility treatment, it is possible to say that the most successful treatment is in vitro fertilization. In IVF treatment, the eggs obtained from the mother and the sperm obtained from the father are washed, sorted and fed and developed in the laboratory with some drugs. Then, the best quality, well-structured, mobile, mature and most suitable for pregnancy sperms are selected. The selected quality sperms are placed where the mother’s egg is, and the sperm is expected to fertilize the egg, just like in a natural pregnancy (Embryo Freezing Process). As a result of fertilization, several healthy embryos can be obtained. In order to prevent multiple pregnancies, in particular, a single embryo is usually placed in the mother’s womb, but in some special cases, two embryos can be transplanted.

Why is it not considered appropriate to transplant more than 2 embryos in IVF treatment?
Embryo Freezing Process; Placing more than one embryo in the uterus of the expectant mother in IVF treatment is most likely a sign that a multiple pregnancy will occur. In the period when IVF treatment was started and even in the last 10 years, even 3-4 embryos were transplanted in order to increase the success rate of the treatment. However, in twin, triplet and quadruplet pregnancies, experiencing health problems during pregnancy, babies not developing well, one or more of them being unhealthy or even losing them made it necessary to impose a quota on embryo transfer. Because there is a huge difference between a mother-to-be carrying one baby in her womb and carrying three babies.
In order not to endanger the health of the mother and baby, and to ensure that the baby in the mother’s womb can be fed and grown as needed, a single embryo or a maximum of two embryo transfers at a time is considered appropriate. For this reason, if more than one healthy embryo is obtained when fertilization is performed at the beginning of the IVF treatment, the embryos can be frozen and stored in order to use them in the next IVF treatment.
Embryo Freezing in IVF treatment? Why and how to freeze?
Embryo Freezing Process; After one or two of the embryos obtained in IVF treatment are placed in the uterus of the expectant mother, if there are any healthy and suitable embryos left behind, it is best to save them for the next pregnancy plan or IVF trial. Because as time passes, age progresses or as long as drugs are used, reproductive cells decrease and reproductive functions slow down. 1-2 of the embryos obtained in the first IVF application are used, the remaining healthy embryos are mixed with a protective liquid, stored in glass ampoules, frozen at -196 degrees in liquid nitrogen.
Embryos, which can be stored for 5 years as permitted by the laws in Turkey, can be kept for more if both men and women wish, at the end of 5 years in return for their signature. When embryos are desired to be used, they are removed from liquid nitrogen and dissolved at room temperature. On the day they are thawed, healthy embryos can be placed directly into the uterus of the expectant mother. Since there is a risk of not getting pregnancy in the first try of IVF treatment or losing the baby while in the mother’s womb, transferring ready-made embryos without the need for re-use of drugs or medical procedures in the next IVF trial will make the job much easier. However, embryo freezing is very advantageous for patients with polycystic ovary syndrome, which occurs as a result of overstimulation of the eggs. Because in this way, the ovaries are stimulated once, a large number of embryos are obtained and the eggs do not need to be stimulated again (Embryo Freezing Process).
