FREEZING – VITRIFICATION

Vitrification causes much more rapid cooling than freezing, and it prevents ice crystals from forming. This process preserves the quality of the cells which increase the chances of success when they are thawed.

EMBRYO VITRIFICATION

Vitrification improves the outcomes of embryo freezing. It’s now a very reliable method and increase success rates as high as those achieved with fresh embryos.

In some situations, it may be decided to vitrify all the embryos in a cycle, and postpone embryo transfer. Sometimes we can do this to help prevent ovarian hyperstimulation syndrome (OHSS).

EGG VITRIFICATION

We can use vitrification to successfully freeze eggs immediately after the collection procedure. Indication:

Women who would like to store eggs before undergoing chemo- or radiotherapy, or other treatments that might affect their fertility in the future.

SPERM FREEZING

When should you need sperm freezing during fertility treatment:

  • Prior to chemo- or radiotherapy
  • Prior to vasectomy
  • Prior to any surgery that may result in impaired fertility
  • Prior to a fertility treatment cycle after sperm has been retrieved via surgery
  • Prior to a fertility treatment cycle as a ‘back-up’ sample for the day of treatment.
