Fertility preservation
Medical efforts to retain fertility despite disease or treatment.
Fertility preservation refers to medical efforts to help individuals retain their ability to procreate, particularly when facing threats to fertility such as cancer treatment, ageing, gender-affirming hormone therapy, or conditions like Polyendocrine metabolic ovarian syndrome (PMOS) and Primary ovarian insufficiency (POI). Research into these methods has grown, partly due to increased survival rates among cancer patients.

- Ovarian protection by GnRH agonists, cryopreservation of ovarian tissue, eggs, sperm, or embryos
Lore & Background
Main methods include semen cryopreservation for males, oocyte cryopreservation, embryo cryopreservation, and ovarian tissue cryopreservation. Semen cryopreservation is the most established method for males. Oocyte cryopreservation is now considered well-established for women. Embryo cryopreservation is the most common method in females but requires hormonal stimulation and is not suitable for pre-pubescent girls or those with hormone-sensitive cancers. Ovarian tissue cryopreservation offers an option for prepubertal girls.
Reader's Guide
Fertility preservation has become a significant field in reproductive medicine, driven by the increasing survival rates of cancer patients and the desire to maintain quality of life after treatment. The article highlights that while some patients regain fertility after chemotherapy or radiotherapy, many do not, and the damage can be permanent. The availability of multiple methods—sperm, egg, embryo, and ovarian tissue cryopreservation—allows for individualized approaches based on age, medical condition, and urgency. Notably, the article notes that a study found 28% of referred patients declined preservation, and 9% were ineligible for medical reasons. Testing for anti-Müllerian hormone (AMH) can help predict post-chemotherapy ovarian function loss. The field also addresses fertility loss from ageing and conditions like PMOS and POI, expanding its relevance beyond cancer care. Ethical and legislative concerns have spurred advances in oocyte cryopreservation as an alternative to embryo cryopreservation.
Did You Know?
- A study found that 28% of patients referred for fertility preservation declined to undergo embryo, oocyte, or tissue cryopreservation.
- Chemotherapies with high risk of gonadotoxicity include procarbazine and alkylating drugs such as cyclophosphamide and busulfan.
- Ovarian tissue cryopreservation can provide a fertility preservation option for prepubertal girls.
- Testing for anti-Müllerian hormone (AMH) is useful in predicting long-term post-chemotherapy loss of ovarian function.
Frequently Asked Questions
Who is Fertility preservation?
Fertility preservation is a branch of reproductive medicine dedicated to helping people retain their ability to have biological children when cancer treatments such as chemotherapy or radiation threaten that ability. It gained prominence as cancer survival rates rose and patients increasingly wanted to plan for parenthood after treatment.
What are Fertility preservation's powers/role?
Its core 'powers' include cryopreserving eggs, sperm, or embryos before treatment starts, as well as administering GnRH agonists to shield ovaries from chemotherapy damage. It can also involve freezing ovarian tissue for later reimplantation, giving patients several options depending on their clinical situation.
How does Fertility preservation's story end?
The narrative arc concludes when a cancer survivor is able to conceive using previously stored gametes or tissue, or when they make an informed decision not to pursue biological parenthood. There is no single fixed ending—the goal is simply to keep the choice open.
Why is Fertility preservation important?
It matters because cancer therapies are often most effective when initiated immediately, leaving very little time to collect eggs or sperm naturally beforehand. By offering rapid, proven methods like sperm freezing or ovarian-tissue cryopreservation, the field prevents irreversible loss of reproductive potential.
What's Fertility preservation's origin story?
The field grew out of the 1980s and 1990s, when advances in oncology meant more young patients survived their diagnoses and began asking about future family planning. Rising survival rates, combined with techniques like IVF and tissue banking, turned what was once an impossible wish into a standard part of the cancer-care conversation.
