Since 1983 surplus fertilized eggs (embryos) have been frozen and stored for later thawing and transfer. Pregnancies following this procedure do not carry enhanced risk of abortion, chromosome abnormalities or malformations.
Danish legislation states:
Frozen fertilized eggs can only be used if both the woman and the man concede on thawing in writing.
Fertilized eggs can only be kept frozen for a period of 5 years. After this time the eggs will be destroyed without warning. The eggs will also be destroyed in case of death of one of the partners or in case of dissolution of the partnership.
Before the freezing down of eggs can take place, you must in writing concede your agreement to freezing and storing and declare your consent to terms and conditions applying.
