Fertility preservation procedures are indicated when it's predicted that there will be exposure to a cause of infertility. Mainly cancer treatment, such as chemotherapy, radiation, and surgery, may destroy a person's ability to have children later in life, and oncofertility research focuses on increasing fertility preservation options. Oncofertility is a subfield that bridges oncology and repro...
