Reproductive Biology and Fertility

Cancer treatments such as chemotherapy and radiation can permanently damage the ovaries, leaving patients who survive their disease unable to conceive. Reproductive biology researchers are developing and refining techniques — including freezing ovarian tissue before treatment begins and later reimplanting it, as well as maturing eggs outside the body — to protect or restore fertility in these patients. A central challenge is understanding exactly how gonadotoxic therapies accelerate the loss of follicles that would otherwise support egg development, and how reproductive aging interacts with that damage at the molecular level. Active work is focused on improving the survival of cryopreserved oocytes and tissue, identifying the growth factors that sustain follicle health, and reducing the small but real risk that reimplanted tissue could reintroduce malignant cells.
