Fertility Preservation in Cancer: a chance for parenthood in the future

Modern oncology increasingly encounters patients who successfully recover from cancer and wish to preserve their ability to have children in the future. Cancer treatments, including chemotherapy, radiation therapy, and surgery, can negatively affect the reproductive system in both women and men. Therefore, fertility preservation in cancer patients has become an important field of medicine, allowing individuals to plan for a family after completing therapy.

In Israel, the Department of Obstetrics and Gynecology at Ichilov has developed effective protocols aimed at protecting reproductive function before the start of oncological treatment.

When it is important to consider fertility preservation

The need to preserve reproductive potential arises in the treatment of various malignant tumors, such as:

• breast cancer;
• ovarian and cervical cancer;
• lymphomas and leukemias;
• brain tumors;
• testicular and prostate cancer in men.

Chemotherapy and radiation therapy, especially in the pelvic and abdominal areas, can destroy eggs and sperm, as well as reduce ovarian and testicular activity. Therefore, it is crucial to discuss fertility preservation with a physician before beginning cancer treatment.

1. Egg (oocyte) freezing

This is one of the most common methods of fertility preservation for women. Before chemotherapy, ovarian stimulation is performed, followed by egg retrieval and freezing. The method is suitable for women under 40 and is particularly relevant in Israel, where advanced cryopreservation technologies ensure a high survival rate of frozen eggs.

2. Embryo freezing

This technique is used for women in a couple. After an IVF procedure, fertilized eggs (embryos) are frozen and can later be used once treatment is complete. This method has one of the highest success rates for subsequent embryo transfers.

3. Ovarian tissue freezing

If treatment must begin immediately and there is no time for ovarian stimulation, a portion of ovarian tissue containing immature eggs can be surgically removed and frozen. Later, this tissue can be transplanted back to restore natural ovulation and fertility. This method is actively practiced at the Ichilov center for Infertility research and treatment, where specialists have extensive experience with such procedures.

4. Sperm freezing

For men undergoing chemotherapy or radiation therapy, sperm banking is recommended. Frozen sperm retains its fertilization potential for many years and can be used for IVF or intrauterine insemination.

In Israel, fertility preservation in oncology is managed comprehensively. At Ichilov, patients receive multidisciplinary care — oncologists, reproductive specialists, and embryologists work together to develop a personalized treatment plan. This collaborative approach minimizes risks and ensures the selection of the most suitable fertility preservation method for each individual.

In addition, patients receive psychological support, as fertility is closely linked to quality of life and emotional well-being during cancer treatment.

Fertility preservation in cancer patients at Ichilov is not merely a technological procedure — it is a holistic medical program that gives patients hope for future parenthood. Advanced cryopreservation techniques, personalized care, and the expertise of Ichilov’s Department of Obstetrics and Gynecology make it possible to preserve reproductive potential even in the most complex clinical situations.

If a patient is facing cancer treatment, it is essential to discuss possible fertility preservation options at Ichilov in advance. This decision can change life after recovery.
