Women diagnosed with cancer who have not yet begun chemotherapy or radiotherapy can benefit from Oocyte cryopreservation. [3] Chemotherapy and radiotherapy are toxic to oocytes, reducing the number of viable eggs. Egg-freezing may be used in this case to preserve eggs as opposed to Oocyte cryopreservation.

A study in France between 1999 and 2011 came to the result that embryo freezing before administration of gonadotoxic chemotherapy agents to females caused a delay of treatment in 34% of cases, and a live birth in 27% of surviving cases who wanted to become pregnant, with the follow-up time varying between 1 and 13 years.

Transvaginal oocyte retrieval (TVOR), also referred to as oocyte retrieval (OCR), is a technique used in in vitro fertilization (IVF) in order to remove oocytes from an ovary, enabling fertilization outside the body. [1]

Egg donation is the process by which a woman donates eggs to enable another woman to conceive as part of an assisted reproduction treatment or for biomedical research. For assisted reproduction purposes, egg donation typically involves in vitro fertilization technology, with the eggs being fertilized in the laboratory; more rarely, unfertilized eggs may be frozen and stored for later use.
Rather than needing to harvest embryos or eggs, which are limited, the researchers can remove mesenchymal stem cells with greater ease and greatly reducing the danger to the animal due to noninvasive techniques. This allows the limited eggs to be put to use for reproductive purposes only.
Plover eggs were a form of eggs as food, and a seasonal delicacy of western Europe. [1] Gathered from wild green-plover nests, [ 2 ] a practice called plover egging , these eggs were perceived to be particularly flavorful and were snatched up by avid rural foragers and, in turn, their urban customers, as soon as nesting season began each year.
