Cryo Preservation

Cryo Preservation of Eggs and Embryos

Enables You to postpone having Children
Embryo vitrification

Vitrification is a new technique to freeze embryos more quickly and efficiently than classical freezing.

This technique helps preserve those embryos which are not transferred to the uterus during an IVF/ICSI or egg donation treatment. In accordance with Spanish Law, it is possible to transfer to the uterus a maximum of 3 embryos in a treatment cycle, so should you have any remaining embryos of good quality, these can be vitrified for possible future treatment.

It also enables the preservation of embryos obtained from IVF/ICSI treatments that cannot be transferred because of the risk of hyperstimulation of the woman.

Embryos can be thawed and transferred to the uterus later on. This technique is called cryo- transfer or FET (Frozen Embryo Transfer).

Egg vitrification

Egg vitrification is a new assisted reproduction technique that enables freezing a woman’s eggs so that they can be used at a later date when she decides to become a mother. In Spain, this procedure has already enabled the birth of several children, with pregnancy rates similar to those obtained with fresh eggs.

This technique is suitable in the following cases:

  • Women who wish to preserve fertility: young women with or without a partner who wish to delay childbearing for personal or professional reasons.
  • Women who have to undergo cancer treatment: chemotherapy and radiation therapy result in irreversible damage to a woman’s eggs, so egg vitrification enables a woman to have a child once the disease is beaten.
  • Couples that do not wish to freeze embryos in assisted reproduction techniques due to moral issues.
  • Women with a low ovarian reserve: this technique enables the accumulation of oocytes, following several cycles of stimulation, prior to the initiation of the chosen assisted reproduction technique.
Sperm freezing

Semen freezing enables a sperm sample to be frozen which can be used at a later date for oocyte fertilization.

This technique is suitable in the following cases:

  • Men who have to undergo cancer treatment: chemotherapy and radiation therapy result in irreversible damage to a man’s semen, so sperm freezing enables the man to become a father and for his partner to have a child once the disease is beaten.
  • When a couple is undergoing fertility treatment it is always recommended that the man has a sperm sample frozen. We can then use that sample to inseminate the eggs that have been collected if the man is unable to produce a fresh sample for any reason.
