Fertility preservation is a critical consideration for cancer patients, especially those of reproductive age, before, during, and after treatment. Cancer therapies, such as chemotherapy and radiation, can damage reproductive organs, leading to infertility. Patients are often offered options like egg, sperm, or embryo freezing prior to starting treatment. New techniques, such as ovarian tissue cryopreservation and testicular sperm extraction, are also gaining popularity. Post-treatment, fertility preservation efforts can help individuals start families, offering a sense of hope and normalcy after a life-altering diagnosis. Counseling services are also available to guide patients through fertility preservation decisions, ensuring that they understand the implications and risks.
