Fertility preservation in BRCA mutation carriers.

Area of Science:

• Oncology
• Reproductive Medicine
• Genetics

Background:

• Increasing long-term survival rates highlight the need for fertility preservation in young women undergoing gonadotoxic therapies.
• BRCA1/BRCA2 mutation carriers face elevated risks of breast and tubo-ovarian cancers, often necessitating premature infertility interventions.
• Fertility concerns impact BRCA carriers, influencing family planning due to prophylactic surgeries and cancer treatments.

Purpose of the Study:

• To review fertility preservation options for young women at high risk of ovarian insufficiency and infertility.
• To discuss strategies for BRCA mutation carriers facing cancer treatment or prophylactic surgeries.
• To emphasize the importance of timely fertility counseling and intervention.

Main Methods:

• Review of validated fertility preservation techniques: oocyte and embryo cryopreservation.
• Discussion of experimental methods: ovarian suppression with GnRH-analogs and ovarian tissue cryopreservation.
• Consideration of factors influencing strategy selection: age, chemotherapy type, partner status, cancer type, and time constraints.

Main Results:

• Validated fertility preservation methods include oocyte and embryo cryopreservation.
• Experimental options comprise GnRH-analogs for ovarian suppression and ovarian tissue cryopreservation.
• Optimal strategy selection is multifactorial, requiring personalized assessment.

Conclusions:

• Prompt fertility preservation counseling is essential for all at-risk young women.
• A combination of approaches can be employed, prioritizing timely cancer treatment.
• Informed choices among available fertility preservation options empower patients.
