Dr. Seval Taşdemir said, “Increasing cancer diseases do not prevent dreams of having a child. You can freeze your eggs or embryos before chemotherapy and radiotherapy treatments. In this way, you can achieve your dream of a baby after cancer treatment.

In which situations does cancer treatment harm reproduction?

Chemotherapy and radiotherapy used in childhood and reproductive cancers harm reproduction. Fertility cancer types; Since there is intensive chemotherapy in breast, cervix, uterus, ovary and thyroid, leukemia and blood diseases that require bone marrow transplantation in childhood, it is important to preserve fertility from these ages. The type, duration, dose and effect of the drug used vary according to age. Especially the agents used in chemotherapy and radiotherapy to the uterus-ovary region damage the reproductive cells.

What methods are used against infertility in cancer?

The method of preventing infertility varies depending on whether the patient is married or not. If the patient is single, freezing the egg or ovarian tissue is preferred. In egg freezing, before chemotherapy (approximately 15 days before), the ovaries are stimulated with drugs and collected and frozen before fertilization. Freezing of ovarian tissue; It is preferred in patients who do not have time for drug therapy, mostly in children. With the laparoscopy method, some of the egg tissue is taken and stored.


If the patient is married, which method is used?

Embryo freezing is preferred first. In embryo freezing, embryos are stored at -196 degrees with the rapid freezing (vitrification) method. After thawing, it maintains its vitality at a high rate. With the advances in freezing techniques, the success rate of achieving pregnancy is similar to fresh applications; It is about 55-60 percent.

How is the freezing process done?

The beginning of the egg freezing process; It is like an IVF treatment protocol. First of all, the eggs are grown properly or the eggs are followed in natural cycles, and then the eggs are collected and stored. Obtained eggs are stored by freezing with various freezing techniques. Especially in recent years, successful results have been obtained with rapid freezing (vitrification).

Cancer patients can have children with ovarian transplant

At present, close to 100 percent viability is achieved after dissolving in embryos and eggs with vitrification. The cell is protected by providing a sudden temperature drop with high concentration freezing solutions for a short time and creating a glass surface around the cell. About two weeks before starting chemotherapy or radiotherapy, the ovaries are stimulated and egg growth is ensured. In cases of breast cancer, since the hormone receptor is positive, the estrogen used to stimulate the ovaries is kept at a low level if the cancer is sensitive to estrogen.


When to get pregnant or start treatment after cancer treatment depends on the type of cancer, stage and duration of medication. Pregnancy is allowed if there is no evidence of cancer in x-ray, MRI and blood tests in cancer screenings after adequate drug dose is provided. According to the regulation of assisted reproductive techniques of the Ministry of Health; The embryo and egg storage period has been determined as five years, and only in some special cases, it has been extended.


Married couples can have embryo freezing with in vitro fertilization treatment. If there are embryos suitable for freezing left after embryo transfer, freezing can be done with the permission of the couples. Egg freezing was used only in cancer patients. However, with the change made in the IVF regulation by the Ministry of Health in the last months of 2014, women with reduced ovarian reserve at an early age or at risk of entering early menopause were allowed to freeze their eggs, provided that they also prove this situation.

Having cancer is not an obstacle to being a mother.

After chemotherapy, menses can return in a period of at least 6-12 months. The improvement in menstruation does not always mean that pregnancy can be achieved. In order to understand whether ovarian functions are affected by the treatment, FSH, E2 (estradiol) and AMH (antimullerian hormone) tests should be performed on the third day of menstruation.


  • Many studies in the world report pregnancies and live births with frozen eggs and putting ovarian tissue in different parts of the body.
  • Increasing survival rates with the advancements in technology and cancer treatments day by day; It also preserves fertility.
  • Chemotherapy and radiotherapy used affect ovarian functions in women and lead to early menopause, which we call premature ovarian failure.
  • For this reason, it is important for oncologists to consider their patients’ desire for children before treatment and in the future.
  • Patients; It should be evaluated by IVF specialists, radiation and medical oncologists and informed about infertility protection methods.
  • A treatment protocol should be established by considering the psychology and thoughts of the patient.
