1 A surplus embryo may only be used for the derivation of embryonic stem cells if written consent has been freely given by the couple concerned. Before such consent is given, the couple must be provided with adequate information, verbally and in writing, in a comprehensible form, concerning the use of the embryo.
2 A request may only be made to the couple after the determination of the surplus status of the embryo.
3 Consent may be revoked by the couple, or by the woman or man, at any time, without any statement of reasons, up until the initiation of stem cell derivation.
4 If consent is refused or revoked, the embryo must be destroyed immediately.
5 In the event of one partner's death, the decision concerning the use of the embryo for stem cell derivation shall be taken by the surviving partner; he or she must have regard to the declared or presumed wishes of the deceased.
