[Ovarian tissue cryopreservation in girls]

Area of Science:

• Reproductive medicine
• Oncology
• Pediatric endocrinology

Context:

• Cancer treatments like chemotherapy and radiotherapy can cause ovarian damage in girls.
• This damage may lead to hormonal dysfunction and subfertility, impacting future reproductive health.
• Fertility preservation discussions are crucial before initiating gonadotoxic therapies.

Purpose:

• To highlight ovarian tissue cryopreservation as a key fertility-preserving option for girls undergoing cancer treatment.
• To review the efficacy and potential of cryopreserving ovarian tissue in prepubertal girls.
• To underscore the importance of discussing fertility preservation before gonadotoxic therapy.

Summary:

• Ovarian tissue cryopreservation is the sole fertility preservation method for prepubertal girls at high risk of premature ovarian failure.
• This technique involves storing numerous follicles for potential transplantation or in vitro maturation into ovocytes.
• Successful births have been reported in adults following ovarian tissue autografting, and prepubertal tissue has demonstrated capacity to induce puberty.

Impact:

• Ovarian tissue cryopreservation provides a viable option for preserving fertility in young female cancer survivors.
• It offers the possibility of achieving natural puberty and future fertility in girls treated with gonadotoxic agents.
• This approach represents a significant advancement in reproductive care for pediatric oncology patients.
