Reasons for approval are the potential physical or mental distress if the pregnancy runs to term; or if the pregnancy arises from a serious crime (e.g. rape or incest) or if an illness of either parent would make it difficult to provide a normal upbringing for the child. Reference to Valvira for review and decision is needed in all cases between 13-20 weeks; or when there are grounds that the fetus is abnormal (in which case the 20 weeks is extended to 24 weeks); or in any case where the doctor has given a negative decision. Above 20 weeks, a threat to the physical life of the mother is the only valid reason for terminating a pregnancy.
