In light of this teaching, can it be morally permissible to freeze or keep frozen a human being, even with the purpose of preserving his life? The CDF’s answer is negative: “Freezing of embryos (cryopreservation) constitutes an offense against the respect due to human beings by exposing them to grave risks of death or harm to their physical integrity and depriving them, at least temporarily, of maternal shelter and gestation, thus placing them in a situation in which further offenses and manipulation are possible” (DV 1:6).
