Fertility Preservation for Women with Cancer: What You Need to Know Before Treatment Begins

A cancer diagnosis is one of the most overwhelming experiences a person can face. In the immediate aftermath, conversations about survival and treatment take center stage. But for women of reproductive age, there is another deeply important question that often gets left until it is too late: what happens to my ability to have children?

Cancer treatments including chemotherapy, radiation, and surgery can cause significant damage to the reproductive system. In some cases, that damage is permanent. But with the right information and prompt action, many women can protect their fertility before treatment begins. This field, known as oncofertility, has advanced dramatically in recent years and today offers real hope for women facing a cancer diagnosis.

At Expecting.Ai, we work with families navigating complex paths to parenthood every day. This guide is for any woman who has been diagnosed with cancer and wants to understand her options before it is too late to act.

Why Cancer Treatment Threatens Fertility

Cancer treatments affect fertility in different ways depending on the type and location of the cancer, the treatment protocol, and the woman's age and ovarian reserve at the time of diagnosis.

Chemotherapy uses powerful drugs that target rapidly dividing cells. Unfortunately, this includes the eggs and follicles in the ovaries. Alkylating agents in particular are highly toxic to the ovaries and can cause premature ovarian insufficiency (POI), sometimes called premature menopause. The risk depends on the specific drugs used, the cumulative dose, and the woman's age.

Radiation to the pelvis or abdomen can directly damage the ovaries and uterus. Even scatter radiation from treatment of other areas can affect ovarian function. In some cases, a procedure called ovarian transposition (oophoropexy) can surgically move the ovaries out of the radiation field before treatment begins.

Surgery for gynecological cancers including ovarian, cervical, and uterine cancer may require removal of one or both ovaries, the uterus, or other reproductive organs, directly affecting fertility.

Approximately 10% of people diagnosed with cancer are under age 40, according to oncofertility research. As cancer survival rates continue to improve, quality of life after treatment, including the ability to have a family, has become an increasingly important consideration.

The Most Important Thing: Act Before Treatment Starts

Timing is everything in fertility preservation. Most options require action before chemotherapy or radiation begins. Once treatment starts, the window for certain procedures closes, sometimes permanently.

The American Society of Clinical Oncology (ASCO) recommends that oncologists discuss fertility preservation options with all patients of reproductive age as early as possible after diagnosis, and refer patients to a reproductive endocrinologist or fertility specialist promptly. Unfortunately, this does not always happen. Many women report that fertility was not mentioned by their oncology team until after treatment had already begun.

If you have been diagnosed with cancer and no one has talked to you about fertility preservation yet, ask. It is a reasonable and important question, and you have the right to a referral to a specialist before your treatment begins.

Fertility Preservation Options for Women with Cancer

The right option depends on your age, diagnosis, the urgency of starting cancer treatment, whether you have a partner, and your personal goals. Here is an overview of the main approaches available today.

Egg Freezing (Oocyte Cryopreservation)

Egg freezing is currently the most common and well-established fertility preservation option for women without a partner. The ovaries are stimulated with hormone injections over approximately 10 to 14 days to produce multiple eggs. Those eggs are then retrieved in a minor procedure and frozen using a technique called vitrification, which has dramatically improved survival rates compared to older slow-freezing methods.

The process typically takes 2 to 6 weeks from start to finish, which means it requires a brief delay in starting cancer treatment. For most cancer types, this delay is acceptable and will not affect outcomes, but this must be confirmed with the oncology team. Egg freezing is now considered a standard of care, no longer experimental, by the American Society for Reproductive Medicine (ASRM).

Embryo Freezing (Embryo Cryopreservation)

Embryo freezing follows the same ovarian stimulation and egg retrieval process as egg freezing, but the retrieved eggs are fertilized with sperm before being frozen. This is the most established method with the longest track record of success. It is typically recommended for women who have a partner or who are comfortable using donor sperm.

Frozen embryos have very high survival rates through the freezing and thawing process, and success rates for embryo transfer are generally higher than for egg freezing alone. However, because the embryos are created with a specific partner's sperm, there are legal and ethical considerations if the relationship changes in the future.

Ovarian Tissue Cryopreservation

Ovarian tissue cryopreservation involves surgically removing a portion of ovarian tissue, which is then sliced into thin strips and frozen. After cancer treatment is complete and the woman is ready to try for pregnancy, the tissue can be reimplanted into the body, where it may resume producing eggs and hormones.

This option is particularly valuable because it does not require ovarian stimulation, meaning it can be performed quickly without delaying cancer treatment. It is also the only option currently available for girls who have not yet reached puberty. The procedure was considered experimental until 2019, when ASRM reclassified it as a standard clinical option. More than 130 live births have been documented worldwide following ovarian tissue transplantation, according to published research.

One important consideration: for certain cancers such as leukemia that may affect the ovaries, there is a theoretical risk that reimplanted tissue could reintroduce cancer cells. This risk varies by cancer type and must be discussed carefully with both the oncology and fertility teams.

GnRH Agonist Therapy (Ovarian Suppression)

Gonadotropin-releasing hormone (GnRH) agonists such as leuprolide are sometimes used during chemotherapy to suppress ovarian function, effectively putting the ovaries into a temporary resting state. The idea is that suppressed ovaries may be less vulnerable to chemotherapy damage.

Evidence on the effectiveness of this approach has been mixed, though some studies, including the landmark POEMS trial for breast cancer patients, have shown benefit in reducing the rate of premature ovarian failure. GnRH agonist therapy is generally considered a complementary option rather than a primary fertility preservation strategy, and does not provide the same level of certainty as egg or embryo freezing.

Fertility-Sparing Surgery

For women with early-stage gynecological cancers, fertility-sparing surgical approaches may allow cancer treatment while preserving the ability to carry a pregnancy. For early-stage cervical cancer, radical trachelectomy removes the cervix while preserving the uterus. For early-stage ovarian cancer, unilateral salpingo-oophorectomy removes only the affected ovary. For early-stage endometrial cancer, hormonal treatment rather than hysterectomy may be appropriate in carefully selected cases.

These approaches require careful patient selection and are not appropriate for all cases. They must be discussed with a gynecological oncologist who has experience in fertility-sparing techniques.

Costs and Financial Assistance

Fertility preservation is expensive. An egg or embryo freezing cycle typically costs $5,000 to $15,000, plus ongoing storage fees. Insurance coverage varies widely and many plans do not cover fertility preservation for cancer patients, though this is slowly changing as more states pass fertility preservation mandates.

Several organizations offer financial assistance specifically for cancer patients seeking fertility preservation, including Livestrong Fertility, which partners with fertility clinics nationwide to offer discounted or free services to eligible cancer patients. RESOLVE: The National Infertility Association also maintains a list of financial resources. Asking your fertility clinic about hardship programs and payment plans is always worthwhile.

Using Preserved Eggs or Embryos After Cancer

Once cancer treatment is complete and a woman has been cleared by her oncology team, frozen eggs or embryos can be thawed and used in an IVF cycle. If cancer treatment has damaged the uterus or if pregnancy poses health risks after certain cancers, gestational surrogacy allows another woman to carry the pregnancy using the intended mother's frozen eggs or embryos.

Surrogacy after cancer is more common than many people realize. Women who have undergone uterine radiation, who have had a hysterectomy, or whose medical team advises against pregnancy can still have biologically related children through surrogacy. At Expecting.Ai, we have helped many cancer survivors build their families through this path, and we understand the unique emotional and logistical considerations involved.

What to Do Right Now

If you or someone you love has just received a cancer diagnosis, here are the immediate steps to take regarding fertility:

• Ask your oncologist about fertility preservation today -- before treatment planning is finalized. Ask specifically whether your treatment plan will affect fertility and whether there is time to pursue preservation before starting.
• Request a referral to a reproductive endocrinologist -- ideally one with experience in oncofertility. Many fertility clinics offer urgent consultations for cancer patients.
• Contact Livestrong Fertility -- if cost is a concern. They can connect you with partner clinics and financial assistance programs.
• Ask about all your options -- not just egg freezing. Depending on your situation, ovarian tissue preservation, embryo freezing, or other approaches may be more appropriate.
• Document everything -- keep records of all consultations, procedures, and stored materials. You will need this information years from now.

You Do Not Have to Choose Between Surviving and Having a Family

A cancer diagnosis forces impossible choices on people who are already dealing with more than anyone should have to face. But fertility preservation has advanced to the point where, for many women, it is no longer an either/or decision. With the right information, the right specialists, and action taken at the right time, it is possible to fight cancer with everything you have and still keep the door open to the family you dream of.

If you are a cancer survivor or currently undergoing treatment and want to understand your options for building a family through egg donation, embryo transfer, or surrogacy, our team at Expecting.Ai is here to help. We specialize in complex family-building journeys and will meet you exactly where you are.
