Understanding Ovarian Tissue Freezing

Ovarian tissue freezing involves the surgical removal and cryopreservation of a portion of an ovary, preserving the ovarian follicles and thereby the potential for future fertility and natural hormone production. The tissue can be re-implanted at a later date, offering a possibility for pregnancy.

Why opt for Ovarian Tissue Freezing?

  • Medical treatments: For those undergoing treatments, such as chemotherapy or radiation, which could compromise fertility
  • Premature ovarian failure: At risk of early menopause due to genetic factors or other conditions
  • Surgeries: Upcoming surgeries that may impact the ovaries or overall fertility
  • Age: Delaying childbirth for personal reasons and safeguarding against age-related fertility decline

The Process of Ovarian Tissue Freezing

  • Tissue retrieval: A minor surgical procedure, typically laparoscopy, is used to retrieve a part of the ovarian tissue
  • Assessment: The tissue is assessed for quality and the presence of healthy follicles
  • Cryopreservation: The ovarian tissue is carefully prepared with cryoprotectants and then slowly frozen to preserve cellular integrity
  • Storage: The frozen tissue is stored in specialized cryogenic storage tanks until the patient decides to use them

What next after freezing?

When a woman is ready, the frozen ovarian tissue can be thawed and then transplanted back into her body. The re-implanted tissue can restore natural hormone production and fertility. It can potentially lead to natural conception, or if necessary, IVF can be used to achieve pregnancy.
