A cancer diagnosis brings immediate, overwhelming concerns — but for patients of reproductive age, one question often rises alongside immediate treatment decisions: will I still be able to have children after treatment? Oncofertility — the intersection of oncology and reproductive medicine — has made remarkable advances in preserving fertility options for cancer patients before gonadotoxic treatment.
Why Timing Matters
Many chemotherapy agents and radiation treatments directed at or near reproductive organs can permanently damage fertility. The degree of impact depends on the specific agents used, cumulative doses, patient age, and baseline ovarian/testicular health. Fortunately, fertility preservation procedures can often be completed in 2–3 weeks — fitting within the timeframe before most oncology treatment begins.
Early consultation with a reproductive endocrinologist — ideally within days of diagnosis if fertility preservation is a priority — allows the fertility preservation plan to be integrated with the oncology treatment timeline without causing harmful delays to cancer treatment.
Egg Freezing for Female Cancer Patients
Ovarian stimulation and egg freezing is the most established fertility preservation option for female cancer patients. The process involves 10–12 days of injectable hormone medications to stimulate multiple follicle development, followed by an outpatient egg retrieval procedure. Retrieved eggs are immediately vitrified and stored in liquid nitrogen.
For patients with hormone-sensitive cancers, modified stimulation protocols using letrozole or tamoxifen can keep estrogen levels lower during stimulation — an approach developed specifically for oncofertility applications that reduces theoretical risk while still producing viable eggs for freezing.
Embryo Freezing
Patients with a partner may choose to create embryos before treatment rather than freezing unfertilized eggs. Modern egg freezing outcomes now approach embryo freezing success rates. The choice between egg and embryo freezing depends on relationship status, personal values, and specific clinical factors.
Ovarian Tissue Cryopreservation
For patients who cannot delay treatment long enough for ovarian stimulation, ovarian tissue cryopreservation offers an alternative. This procedure involves removing and freezing ovarian tissue before treatment, then reimplanting it after cancer treatment is complete. This approach has resulted in hundreds of births worldwide.
The Fertility Institute of San Diego provides urgent fertility preservation consultations for newly diagnosed cancer patients, working directly with oncology teams to develop preservation plans that protect reproductive potential without delaying cancer treatment.
If you’ve recently received a cancer diagnosis, contact the Fertility Institute of San Diego’s oncofertility program immediately for an expedited consultation tailored to your treatment timeline.
