Preserving fertility in female cancer patients through ovarian tissue freezing

Ovarian Tissue Cryopreservation and Subsequent Auto-Transplantation for Female Cancer Patients

Not applicable Interventional Chinese University of Hong Kong · NCT05830929

This study is testing a method to freeze ovarian tissue for female cancer patients who don't have time for regular fertility preservation, helping them protect their ability to have children later.

What this trial studies

This project aims to provide ovarian tissue cryopreservation for female cancer patients who lack sufficient time for traditional fertility preservation methods like oocyte or embryo freezing. The approach includes consultations with fertility specialists to discuss the procedure and associated risks. Following the collection of ovarian tissue via surgery, the tissue will be cryopreserved using either slow freezing or vitrification techniques. This method is particularly beneficial for prepubertal girls and those undergoing treatments that may harm their fertility.

Who should consider this trial

Good fit: Ideal candidates are female cancer patients aged 0-35 who are at risk of fertility loss due to their treatment.

Not a fit: Patients who are pregnant or those without anticipated oncologic therapies may not benefit from this procedure.

Why it matters

Potential benefit: If successful, this could enable female cancer patients to preserve their fertility and have the option to conceive in the future.

How similar studies have performed: Other studies have shown promise in fertility preservation techniques, making this approach a valuable option for patients facing similar challenges.
