“A child is not something owed to one, but it is a gift. The supreme gift of marriage is a human person. A child may not be considered a piece of property, an idea to which an alleged “right to a child” would lead. In this area, only the child posses genuine rights; the right “to be the fruit of the specific act of the conjugal love of his parents” and the right to be respected as a person from the moment of his conception”.. The Gospel shows that physical sterility is not an absolute evil. Spouses who still suffer from infertility after exhausting legitimate medical procedures should unite themselves with the Lord’s Cross, the source of all spiritual fecundity. They can give expression to their generosity by adopting abandoned children or performing demanding services for others” (CCC. Paras2378-2379)
