In dealing with reproduction, the Church believes that every human being has a beginning but has no end; this is why conception constitutes an event of unique importance. The exact moment of the beginning of life is unknown to man, but the logic of sexual intercourse without reproduction and of reproduction without sexual intercourse must be seen with concern. Irrespective of the way it is conceived, the embryo has both a human beginning and a human perspective and in it, along with cellular multiplication, another process takes place, the beginning and development of its soul. Although modern technology has greatly contributed to health research, its irrational use threatens to desacralize man and to treat him as a machine. For this reason, all modern techniques of artificial fertilization have ethical and spiritual parameters that compel the Church to state Her reservations. The Church cannot recommend assisted reproduction as the solution to infertility; instead, She proposes a non-secularized perception on life that guarantees simplicity, peace, abstinence and mutual trust between spouses. She does not oppose resorting to medical help, but, at the same time, suggests that men and women render their life into the hands of God.
