Fertility Preservation Before Medical Treatment

A cancer diagnosis, an autoimmune condition requiring cyclophosphamide, a genetic condition necessitating gonadectomy: each of these scenarios can threaten future fertility. Fertility preservation is the process of banking reproductive cells or tissue before the damaging treatment begins, and it has become an established part of oncology and rheumatology care rather than an afterthought.

If you or someone you care about is facing a treatment that may affect fertility, this guide covers what is available, how fast it can happen, and what decisions need to be made.

Who Should Consider Preservation

The ASCO (American Society of Clinical Oncology) guideline is clear: fertility preservation should be discussed with all patients of reproductive age before gonadotoxic treatment. But "gonadotoxic" extends beyond chemotherapy:

• Alkylating chemotherapy agents (cyclophosphamide, ifosfamide, busulfan) carry the highest risk
• Pelvic radiation, even at moderate doses, can damage ovaries and testes
• Surgical removal of reproductive organs
• High-dose immunosuppressive therapy for autoimmune disease
• Gender-affirming hormone therapy and surgery
• Bone marrow transplant conditioning regimens

Preservation Methods Compared

Egg Freezing: The Rapid-Start Protocol

Traditional IVF protocols start stimulation on day 2 or 3 of the menstrual cycle. In urgent situations, random-start protocols begin stimulation on whatever cycle day the patient presents, with comparable egg yields. This innovation has made it possible to complete egg retrieval within two weeks of the decision to preserve.

The process involves 8 to 12 days of daily injectable gonadotropin medications, 3 to 4 monitoring appointments (ultrasound and blood work), a trigger injection, and an outpatient retrieval procedure under sedation. Modern vitrification techniques achieve egg survival rates above 90% after thawing.

Sperm Banking: The Fastest Option

Sperm cryopreservation is the simplest and fastest preservation method. A semen sample is collected, processed, divided into multiple vials, and frozen. Most labs recommend banking 2 to 3 samples if time allows, to ensure adequate supply for future use.

For men who cannot produce a sample through ejaculation (due to illness, medication effects, or psychological barriers), surgical sperm retrieval (TESE or microTESE) is available, though it requires more planning and coordination.

For Prepubertal Patients

Children who have not gone through puberty cannot produce mature eggs or sperm. Ovarian tissue cryopreservation, which involves surgically removing and freezing a piece of the ovary, is now considered a standard (no longer experimental) option for female patients. After cancer treatment, the tissue can be reimplanted and may restore both fertility and natural hormone production.

Testicular tissue cryopreservation for prepubertal boys remains experimental, with research ongoing at major pediatric oncology centers. Families should discuss enrollment in research protocols with their treatment team.

Financial Assistance

Cost should not be the reason someone skips preservation. Several resources exist:

• LIVESTRONG Fertility offers discounted and free fertility preservation services through partner clinics
• Many fertility clinics offer oncofertility discount programs
• State mandates requiring insurance coverage of medically indicated fertility preservation are expanding
• Pharmaceutical companies sometimes provide free or reduced-cost medications for preservation cycles

The Conversation to Have Now

If treatment is imminent, the single most important step is raising the topic with your medical team. Ask: "Will this treatment affect my ability to have children, and should I talk to a fertility specialist before we start?" That one question opens the door to a referral that can happen within 24 to 48 hours at most cancer centers.
