Must Couples Intend to Conceive Each Time They Have Intercourse?

Must Catholic married couples intend to conceive every time they have sex? This article examines recent magisterial teaching on procreation, conjugal love, and why openness to life does not require an explicit intention to achieve pregnancy in every marital act.

Is it necessary for Catholic married couples to intend procreation every time they engage in the conjugal act? The most recent answer given to this question by the Magisterium is no. The following excerpt is from Una Caro, the most recent magisterial document on marriage and monogamy written by the Dicastery for the Doctrine of the Faith and signed by Pope Leo XIV. Here is what it says:

145. An integral vision of conjugal charity does not deny its fruitfulness—that is, the possibility of generating new life—because “this totality, which is required by conjugal love, also corresponds to the demands of responsible fertility.”[232] The sexual union, as a way of expressing conjugal charity, must naturally remain open to the transmission of life,[233] even though this does not mean that procreation must be an explicit goal of every sexual act. In fact, three legitimate situations may occur:

(a) Where a couple cannot have children. Karol Wojtyła explains this magnificently when he recalls that marriage “possesses an inter-personal structure: it is a union and a community of two persons. […] [The couple may be without children for a variety of reasons, but this] in no way deprives marriage of its proper character. The inner and essential raison d’être of marriage is not simply its eventual transformation into a family but is, above all, the creation of a lasting personal union between a man and a woman based on love. […] A marriage which, through no fault of the spouses, is childless still retains its full value as an institution. […] [Such a family] does not lose its significance.”[234]

(b) Where a couple does not consciously pursue a specific sexual act as a means of procreation. Wojtyła also affirms that a conjugal act, “must be an act of love, an act of unification of persons, and not merely the ‘instrument’ or ‘means’ of procreation.”[235]

(c) Where a couple respects the natural times of infertility. Following this line of reflection, Pope Saint Paul VI states: “the Church teaches that married people may then take advantage of the natural cycles immanent in the reproductive system and engage in marital intercourse only during those times that are infertile.”[236] This can serve not only for “spacing births,” but also to choose the most opportune moments to welcome new life. In the meantime, the couple can take advantage of such periods to “express their mutual love and safeguard their fidelity toward one another. In doing this, they certainly give proof of a true and authentic love.”[237]

146. All of this shows the important innovation Pope Pius XI offers when he states that conjugal love “pervades all the duties of married life and holds pride of place in Christian marriage.”[238] In this way, he helps to move beyond the discussion about the relationship between the ends or meanings of marriage (the procreative and the unitive) and the order that exists between them, by placing conjugal charity above this dialectic of ends and goods as the central issue of married life, which, in turn, gives marriage a multifaceted fruitfulness. Even in the most challenging moments, spouses can say: “We are friends, we love each other, and we value one another. We have decided to share our entire lives. We belong to one another, and we have freely chosen this union that God himself has blessed and strengthened. If at a given moment there are no children, we remain united and find fruitfulness in other ways. If at a given moment there is no sexual intercourse, we continue to live this unique, exclusive, and all-encompassing friendship, which is also our best path of growth and sanctification.” 

This excerpt clearly teaches that married couples are free to engage in the marital act while not intending to conceive regardless of whether a couple is infertile, practicing natural family planning, or simply desires to engage in the marital act with each other but does not desire to conceive. Alongside the already established teaching that each marital act must retain its intrinsic relationship to procreation and that contraception is prohibited, the teaching in this document does not require any that the couple have any other motive for having intercourse, except that it “must be an act of love, an act of unification of persons”. That the marital act can be legitimately engaged in while not intending conception, either due to permanent infertility or by taking advantage of the infertile periods in the cycle of the wife, has been clearly taught in every magisterial document on the matter since Casti Connubii. However, the inclusion of point “b” in the list of the three legitimate situations leaves no room for doubt on the matter. The point is emphasized even further by saying that there has been movement “beyond the discussion about the relationship between the ends or meanings of marriage (the procreative and the unitive) and the order that exists between them, by placing conjugal charity above this dialectic of ends and goods as the central issue of married life” which also leaves no room for doubt that the Church has moved beyond the use of the language of “procreation as the primary end”, while not denying that the procreative significance sexual act is essential to it by stating clearly the requirement of the sexual act to “naturally remain open to the transmission of life”. From this teaching it is clear that married couples are not morally required to intend to conceive each time they engage in the marital act, and that they need no other motivation to make the marital act legitimate as long as it is done out of love for each other.
