Summary
Fertility preservation through ovarian tissue cryopreservation offers hope for patients with diseases risking ovarian failure. This experimental technique allows future transplantation, even for prepubertal girls.
Area of Science:
- Reproductive Medicine
- Oncology
- Cryobiology
Background:
- Malignant and non-malignant diseases pose a risk of ovarian failure.
- Fertility preservation is crucial for affected individuals, especially prepubertal girls.
- Ovarian cryopreservation and autotransplantation are emerging as viable strategies.
Purpose of the Study:
- To review the current strategies and outcomes of ovarian tissue cryopreservation for fertility preservation.
- To highlight the potential of ovarian autotransplantation following cancer treatment.
- To emphasize the importance of a multidisciplinary approach in fertility preservation.
Main Methods:
- Ovarian cortical tissue or whole ovary removal via laparoscopy.
- Application of slow freezing and vitrification techniques to preserve ovarian follicles.
- Orthotopic or heterotopic ovarian tissue transplantation after disease remission.
- Confirmation of malignant cell absence in the graft before autotransplantation.
Main Results:
- Ovarian cryopreservation provides a fertility preservation option when other methods are unsuitable.
- Laparoscopic removal allows for timely initiation of chemotherapy.
- Vitrification and slow freezing minimize follicular damage.
- Successful autotransplantation restores ovarian function post-treatment.
Conclusions:
- Ovarian cryopreservation and autotransplantation are promising experimental approaches for fertility preservation.
- This method is currently the sole option for fertility preservation in prepubertal females.
- A collaborative approach involving oncologists and reproductive endocrinologists is essential for successful outcomes.
