Fertility Cryopreservation

Cyprus IVF Clinic


The leading destination for fertility treatments and stress-free travel offers hope to patients around the world. With the numerous advancements in in vitro fertilization (IVF), cryopreservation techniques have allowed ‘preserving’ eggs, embryos, and sperm a well-established technology at the Kyrenia IVF Center Cyprus.

Oocyte (Egg) Cryopreservation began in 1986, however the application of the method only began in recent years. It is the process whereby a woman’s eggs are extracted, frozen and stored.

They can then be used at a later stage when to become pregnant where they are then thawed and fertilized in preparation for an embryo transfer.

Benefits of Egg Cryopreservation

Women who choose to freeze their eggs do so for a number of reasons. These include:

  • To avoid the risk of premature ovarian failure due to; Chemotherapy, Endometriosis, Ovarian surgery, Genetic predisposition e.g. women with a family history of early menopause
  • Allow flexibility for the IVF process due to; failure to produce semen, risk of ovarian hyper-stimulation syndrome (OHSS)
  • Family Planning; to preserve their future ability to have children either because they do not yet have a partner, for the purpose of education or career or for other personal or medical reasons
  • Oocyte donation

The egg retrieval process for oocyte cryopreservation is the same as for IVF. Hormone injections are administered to stimulate the ovaries and a ovulation trigger injection is used to stimulate the final maturation of eggs in the ovaries. Approximately 34-36 hours later the eggs are collected under transvaginal ultrasound guidance and sedation. The eggs are then immediately frozen.

The survival rate of the oocytes after thawing is 69-100% depending on the quality — and pregnancy rates are nearly 23-35%. These rates are similar to those of cryopreserved embryos.
