Female cancer patients are also at risk of infertility due to cancer treatments. Egg freezing (oocyte cryopreservation) and embryo freezing prior to treatment are common fertility preservation methods. In cases where a partner's sperm is available, embryos can be created and frozen for later use. If eggs are frozen, they can be fertilized via ICSI after thawing, which can be particularly useful if the partner has poor sperm quality.
