Fertility Preservation for Cancer Patients
As cancer treatments continue to improve and survival rates increase, more patients are looking beyond their immediate battle with cancer to their future quality of life. One crucial aspect of this is fertility preservation. Modern technology makes it possible to maintain cancer patients’ fertility, which is a key consideration for oncological care.
Why is fertility preservation becoming a popular topic in oncology?
The growing focus on fertility preservation for cancer patients stems from several interrelated factors. As cancer survival rates continue to improve, more patients are living longer, making future family planning a priority. Young adults and middle-aged individuals, specifically those between 15 and 44 years old, have shown the most promising cancer survival outcomes. A study in the US of five-year survival rates for this age group ranges from 60% to 82%, with variations depending on factors such as the patient's exact age, the location of the tumour, and the country where treatment is received. This relatively high survival rate underscores the importance of considering long-term quality of life issues, including fertility preservation, for these patients.
This shift has coincided with significant advancements in reproductive technology and a marked increase in awareness among both patients and healthcare providers about the potential impact of cancer treatments on fertility. This heightened understanding has led to more proactive discussions and planning, with growing recognition that fertility concerns play a crucial role in the long-term well-being and quality of life for cancer survivors. Together, these factors have propelled fertility preservation to the forefront of comprehensive cancer care, ensuring that patients can look forward to fulfilling lives beyond their cancer diagnosis.
Impact of cancer on reproductive health
For both men and women, cancer treatments can have temporary or permanent effects on fertility. The impact depends on factors like cancer type, treatment used, age, and baseline fertility.
Male reproduction: Chemotherapy, particularly alkylating agents, can damage both sperm and the cells responsible for sperm production. Radiation therapy directed at reproductive organs, the abdomen, pelvis, or spine can lead to decreased sperm counts and lower testosterone levels. Additionally, hormone therapies used in some cancer treatments may result in reduced sperm production. These effects can be temporary or permanent, depending on the specific treatment and individual factors.
Female reproduction: Chemotherapy and radiotherapy can be particularly damaging to ovarian follicles, significantly reducing ovarian reserve. Surgical interventions, especially those involving the reproductive organs, may cause anatomical or vascular issues that affect fertility. Furthermore, certain cancer treatments can trigger premature ovarian failure or early menopause, which can have long-lasting effects on female reproduction and overall hormonal health. The extent and permanence of these effects can vary based on the type and intensity of treatment, as well as the woman's age and baseline fertility.
What are the options for fertility preservation?
For people with sperm:
Sperm cryopreservation aka sperm banking is the primary method (more information here)
Testicular tissue cryopreservation is an experimental option for pre-pubertal boys.
For people with eggs:
Egg or embryo (fertilized eggs) cryopreservation (more information here)
Ovarian transposition (for pelvic radiation)
Ovarian tissue cryopreservation (still considered experimental)
Ovarian suppression with medications (though evidence is limited)
Spotlight on Ovarian Transposition: A Unique Approach
Ovarian transposition is a surgical procedure used to preserve fertility and ovarian function in women facing pelvic radiation therapy for cancer treatment. This technique involves moving the ovaries out of the radiation field to minimize their exposure to harmful radiation. During the procedure, typically performed laparoscopically, the surgeon carefully relocates the ovaries to the upper abdomen or behind the uterus, away from the area that will receive radiation.
This method offers several unique benefits compared to other fertility preservation options like egg or embryo freezing:
Preserves natural hormone production, avoiding the need for hormone replacement therapy.
Allows for potential spontaneous pregnancy after cancer treatment (i.e. natural conception), though this depends on whether the uterus is preserved.
Can be performed quickly without delaying cancer treatment.
More cost-effective than egg or embryo freezing.
Suitable for patients who don't have time for egg harvesting or are too young for other methods.
Setting up your healthcare team
Working effectively with your oncologist and healthcare team on fertility preservation requires proactive communication and thorough planning. It’s best to initiate discussions about fertility concerns immediately after your diagnosis. Request a referral to a fertility specialist to explore all available preservation options, and carefully consider how these methods might impact your cancer treatment timeline. Don't hesitate to ask detailed questions about the specific risks your treatment plan poses to your reproductive health, the safety of future pregnancies post-treatment, and any financial concerns related to fertility preservation. Some Canadian provinces, like Ontario and Quebec, offer covered fertility preservation cycles for cancer patients. By taking these steps, you can work collaboratively with your medical team to make informed decisions that balance your cancer treatment needs with your future family planning goals.
Remember, you are your own best advocate in this journey. While your healthcare team is there to guide you, it's crucial to voice your concerns, ask questions, and actively participate in decision-making about your treatment and fertility preservation options. Don't underestimate the emotional impact of these decisions; seek out mental health support and resources to help you navigate the stress and complex emotions that may arise. Many cancer centers offer counseling services or support groups specifically for patients dealing with fertility concerns. By advocating for yourself and seeking the right emotional and mental health support, you can approach this challenging time with resilience and hope, knowing that you're taking proactive steps to protect both your health and your future family possibilities.

Every individual's situation is unique, and cancer treatments can have varying effects on fertility. If you are facing a cancer diagnosis and have concerns about fertility preservation, it is crucial to consult with your oncologist, a fertility specialist, and other relevant healthcare providers. They can provide personalized advice based on your specific medical history, cancer type, and treatment plan. Always seek the guidance of qualified medical professionals for any health-related decisions or concerns.
