Facing a cancer diagnosis can feel overwhelming, and it often comes with a whirlwind of decisions that need to be made quickly. While addressing the diagnosis and planning treatment are top priorities, it’s equally important to consider how these treatments might impact long-term quality of life—especially regarding future fertility.
Who’s Affected
Cancer treatments can significantly impact fertility, and the level of risk varies depending on the treatment used. For instance, drugs like cyclophosphamide are notorious for being harmful to both sperm and eggs, while others, such as methotrexate, pose less risk. Longer treatment durations generally increase the likelihood of fertility issues, and older patients may experience more severe effects compared to younger ones. High-dose radiation therapy can also affect reproductive cells, although surgery and anesthesia typically do not have direct impacts.
It’s tough to pinpoint exact fertility risks tied to specific chemotherapy regimens, but we do know that more aggressive treatments, like stem cell transplants for leukemia, can carry higher risks. For instance, women under 40 who undergo conventional chemotherapy for breast cancer face about a 50% chance of infertility, while that risk soars to over 80% for older women.
Exploring Treatment Options
For those diagnosed with cancer, the best fertility preservation options are available before starting treatment, primarily through cryopreservation. Once treatment begins, the chances of maintaining fertility decrease, and recovery post-treatment may not be sufficient for pregnancy.
Cryopreservation allows for long-term storage of reproductive cells. Believe it or not, sperm can be stored for decades—28 years is the record for sperm cryopreservation leading to pregnancy! The science behind this involves reducing ice crystal formation that can damage cells, utilizing advanced cryopreservation techniques.
For Men:
The process is fairly straightforward—sperm can be collected and frozen in multiple samples. Typically, 2-3 samples can be processed weekly, resulting in a stockpile for future use. Costs can vary but generally range from $1500 to $3000 for processing and three years of storage.
For Women:
There are two primary options—cryopreservation of oocytes (egg freezing) or embryos. For those without partners, egg freezing offers flexibility without needing to select a sperm donor. Women with partners can opt for embryo freezing, which has a strong track record for success. The process involves hormone stimulation, egg retrieval, and subsequent freezing, with newer techniques showing promising pregnancy rates.
Ovarian tissue cryopreservation is still experimental and hasn’t seen widespread success, as it’s more complex than freezing individual cells.
Risks and Considerations
One question many have is whether using fertility drugs poses a risk for cancer recurrence. Current studies suggest that fertility medications do not significantly increase the risk of breast or ovarian cancer. However, the relationship between pregnancy and cancer recurrence remains complex and requires personalized treatment decisions.
Keep in mind that certain cancer treatments can lead to organ toxicity, which is crucial to consider when planning for pregnancy. For example, those who have received doxorubicin may have limited heart output, and uterine radiation could lead to complications like miscarriage.
As for children born after fertility preservation, studies show no increased risk for birth defects. However, some hereditary syndromes linked to cancer could be passed on, so it’s wise to consult a healthcare professional.
Ultimately, those considering conception should weigh their life expectancy and personal circumstances. These decisions are deeply personal and should be made with support from loved ones.

In summary, cancer diagnosis not only poses serious health questions but also impacts future fertility. Understanding the available preservation methods, along with the associated risks, can empower patients to make informed decisions. Remember, support is vital in these challenging times, so lean on your loved ones and healthcare team for guidance.
