Outcome Measures

Primary Outcomes (1)

  • Surgical complications

    Surgical complications after ovarian tissue transplantation

    15 years

Secondary Outcomes (1)

  • Pregnancy rate

    15 years

Study Arms (1)

Ovarian tissue freezing and subsequent auto-transplantation after thawing

EXPERIMENTAL

Ovarian tissue freezing and subsequent auto-transplantation after thawing

Procedure: Ovarian tissue freezing and subsequent auto-transplantation after thawing

Interventions

Removal of the ovarian tissue will be retrieved via laparoscopic surgery under general anesthesia. The ovarian cortical tissue obtained will be transferred on ice to the laboratory for cryopreservation. After medical treatment, if the patient would like to start a family but has experienced premature ovarian failure, she will have ovarian tissue auto-transplantation after thawing.

Eligibility Criteria

Age1 Month - 35 Years
Sexfemale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Patients aged from 0-35 years old and diagnosed with cancer e.g., leukaemia, myeloproliferative or myelodysplastic diseases, lymphoma, bone tumours, neurological neoplasms and sarcoma, Paediatric bone marrow transplant patients
  • Patients with any illness or who will undergo any type of treatment that may cause irreversible damage to their fertility, such as extensive abdominal surgery, high toxicity medication and treatments;
  • Patients suffering from hormone-sensitive malignancies who will undergo medical treatment, such as radiotherapy and chemotherapy that is liable to damage their ovaries and deter them from conception in the future.

You may not qualify if:

  • Patients with no anticipated oncologic therapies
  • Patients who are pregnant
  • Children with one ovary
  • Children deemed high risk for perioperative complications
  • Patients unable to provide consent/assent (i.e. significant psychiatric problems/cognitive delay)
