Fertility preservation

When to think about cryopreservation?

  • When a woman or a man is expecting cancer treatment, cryopreservation should be considered.
  • If you are thinking about postoponing having children after turning 30 years. Sadly the quality of both sperm and eggs will be lowered and it may be difficult for you to get pregnant.
  • Preserving your sperm and eggs early in life that is before turning 30 is a method that can increase the chances of pregnancy.
  • It is possible to fertilize an egg with thawed or fresh sperm and versa.

Vitrification / Cryopreservation

Vitrification is a more modern cryopreservation method, during which the reproductive cells (sperm, eggs and embryos) are rapidly cooled to -196 °C within one second. Media containing high concentrations of cryo-protective substances, protecting cells from damage, are used during this method of freezing.

Reproductive cells can be stored in this manner for many years. In spite of the standardised procedures, not all embryos survive the process of freezing and thawing in a condition enabling transfer into the woman’s uterus.
