Contraception / IVF
40. Heterologous fertilization (that is, any technique used to achieve conception by the use of gametes coming from at least one donor other than the spouses) is prohibited because it is contrary to the covenant of marriage, the unity of the spouses, and the dignity proper to parents and the child.
41. Homologous artificial fertilization (that is, any technique used to achieve conception using the gametes of the two spouses joined in marriage) is prohibited when it separates procreation from the marital act in its unitive significance (e.g., any technique used to achieve extracorporeal conception).
48. In case of extrauterine pregnancy, no intervention is morally licit which constitutes a direct abortion.
42. Because of the dignity of the child and of marriage, and because of the uniqueness of the mother-child relationship, participation in contracts or arrangements for surrogate motherhood is not permitted. Moreover, the commercialization of such surrogacy denigrates the dignity of women, especially the poor.
52. Catholic health institutions may not promote or condone contraceptive practices but should provide, for married couples and the medical staff who counsel them, instruction both about the Church’s teaching on responsible parenthood and in methods of natural family planning.
53. Direct sterilization of either men or women, whether permanent or temporary, is not permitted in a Catholic health care institution. Procedures that induce sterility are permitted when their direct effect is the cure or alleviation of a present and serious pathology and a simpler treatment is not available
