Cryopreservation in IVF

Cryopreservation is a new trend in Assisted Reproductive Techniques which has a great role in the management of different issues especially fertility preservation.

Types of Cryopreservation:

1. Semen Cryopreservation (sperm banking)

It is a procedure to preserve sperm cells It can be used to preserve fertility for men undergoing vasectomy or treatments that may compromise their fertility, such as chemotherapy, radiation therapy and surgery.

 

2. Human oocyte Cryopreservation (egg freezing) 

  • The eggs are extracted, frozen and stored to help the woman have the eggs thawed, fertilized and transferred to the uterus as embryos in the future.
  • The procedure success rate varies according to the age of the patient( being higher in younger ages) the fluid content of the oocyte, the mitotic spindle and zone hardening.
  • This procedure is helpful in cancer patients who have not begun chemotherapy or radiotherapy.
  • Patients who like to preserve fertility in the future either due to absence of partner or other medical and personal causes.

 

3. Embryo Cryopreservation:

Preservation of the embryo during an embryogenesis stage from fertilization to  the blastocyst stage.  It is useful for leftover embryos after a previous cycle of IVF or ICSI to help patient to avoid a full IVF cycle.

Techniques used for embryo Cryopreservation:

  • The main techniques are vitrification versus slow programmable freezing
  • Vitrification in IVF can allow freezing of spare embryos with better post_ thaw survival rates and higher pregnancy and live birth rates from frozen embryo transfer cycles due to lesser incidence of DNA breaks.
  • Bedaya hospital has more than twenty tanks for Cryopreservation serving thousands of cases using the vetrification technique for all cases of embryo and oocyte Cryopreservation
  • This service is available with the lowest cost for more than twenty years with best quality.
