Cryopreservation I

  • Oocyte cryopreservation is performed for patient
    • at a risk of premature ovarian failure (POF).
    • at a risk of losing ovary function due to cancer treatments.
    • at a risk of developing ovarian hyperstimulation syndrome or endometrial hyperplasia.
    • who wants to postpone childbearing or use an oocyte donation program.
    • who have surplus oocytes for the next use.
  • Embryo cryopreservation
    • Cryo-storage of surplus embryos after embryo transfer for the next use.
    • Women who are at a high risk of developing severe ovarian hyperstimulation syndrome following ovarian stimulation.

Cryopreservation II

  • Semen (sperm) Freezing

When semen collection is not available on the day of IVF or IUI treatment, it is also applied when the patient is at a high risk of losing testicular function following cancer chemotherapy or radiotherapy.

  • Testicular tissue Freezing

After surgical retrieval methods (TESE, PESA and MESA of obstructive azoospermia) were performed to collect sperm, surplus testicular cells or tissues are cryo-storaged for the next use.
