There are many different methods to increase the success rate of IVF treatment. Freezing reproductive cells or embryos is among these techniques, and their success rates are quite high.

By freezing and later using embryos, egg or sperm cells, the chances of pregnancy can be significantly increased. Although these are relatively simple procedures, it is extremely important that the clinic performing the freezing process adheres to established protocols, has experience with the procedure, and has a specially trained team.

Embryo Freezing

Embryo freezing is a preferred method, especially if the age of the expectant mother is advanced and high-quality embryos have been obtained. High-quality embryos are frozen for future use.

Especially after an unsuccessful attempt, if frozen embryos are available, they can be transferred into the uterus of the expectant mother without restarting the IVF treatment process. The experience of the IVF team in freezing and thawing embryos is very important.

Egg Freezing

The egg freezing procedure must be performed by experts in the field. In our country, egg cells can only be frozen under medical necessity. This method is particularly valid for women who will undergo cancer treatment or are at risk of losing their ovaries due to other illnesses.

This is a very important technique to preserve fertility after the patient’s treatment is completed. The frozen egg cells are later fertilized with the sperm cells of the prospective father to begin IVF treatment.

Sperm Freezing

Today, sperm freezing is one of the most successfully applied treatment techniques. However, it is very important that the clinic performing the procedure is experienced and follows protocols properly.

Sperm freezing can be performed for various reasons. It can be used to preserve the fatherhood potential of a male patient prior to cancer treatment or radiotherapy, or in cases where there is a risk of a decrease in sperm count.

Additionally, in patients with no detectable sperm cells (azoospermia), sperm can be retrieved through methods such as TESE or TESA-PESA (testicular biopsy or needle aspiration) to be used in IVF with microinjection.

Among the retrieved sperm, only the amount needed to fertilize the eggs is used, and the remaining quality sperm can be frozen for future use. If these frozen sperm are of good quality, they can be thawed and used without repeating the procedure during the next treatment cycle.
