Today we are able to preserve fertility with in vitro fertilization and very effective freezing (vitrification) methods in cancer cases of both women and men.

Reproduction Protective Processes in Woman:

Unfortunately, chemotherapy or radiotherapy can cause permanent/temporary damage to the ovarian reserve and in some cases completely eliminate the chance of fertility. Therefore, procedures for the protection of fertility are very important in couples who are unmarried or married and have no children or who are married and have children, but have not yet completed their family. Our effective freezing (vitrification) methods increase our chances of success in this context. In these couples, we plan to transfer the frozen gamet/embryo after the cancer treatment with the permission of the relevant branch doctor and medical oncologist.

In the use of chemotherapy and radiotherapy, the form, dose, duration, age of the woman and the ovarian reserve determine the rate of ovarian failure after cancer treatment.

Steps of reproduction protective processes in women are; 

  1. Freezing egg cells,

  2. Freezing egg tissue,

  3. Embryo freezing.

None of these procedures adversely affects the patient's course of cancer.

Classical in vitro fertilization is performed for egg cell freezing and the appropriate embryos obtained are frozen. In the freezing of egg cells, vitrification method provides a very high survival rate after thawing. Even if it is a standard procedure, laboratory quality and experience are very important. In cases like this, 2.5-3 week period may be sufficient to stimulate and collect the ovaries. Treatment can be started immediately without any special timing for menstruation; It can be completed in 2.5-3 weeks. In cases where estrogen elevation in blood, such as breast cancer, may adversely affect the course of cancer; with using drugs such as aromatase inhibitors, we both prevent estrogen elevation in the blood and do not give up the number of eggs collected.   

Today, ovarian (ovarian) tissue freezing has come a long way in.

Embryo freezing in married women is another option.

The Regulation on Reproductive Therapies, which entered into force on 30 September 2014, provided the possibility of egg freezing for patients in need of chemotherapy and radiotherapy provided that it is documented by a committee report:

Reproduction Protective Processes in Man:

As in women, sperm can be frozen in men who have been diagnosed with cancer and who are scheduled for toxic treatment (chemotherapy / radiotherapy) to testicular function. 

According to the new IVF Regulation, which came into force on 30 September 2014, sperm samples may be frozen in any of the following cases provided that they are documented by a committee report.

  1. Before treatments that may damage sperm cells such as chemotherapy and radiotherapy,

  2. Prior to surgeries that would lead to loss of reproductive functions (removal of testicles and the like),

  3. In case of obtaining sperm by surgical methods,

  4. Sperm freezing may be planned in case of severe sperm count reduction (to avoid the risk of no sperm being found in the future).
