Barrier Methods

Barrier methods attempt to keep the sperm from reaching the egg. Withdrawal occurs when a man removes his penis from a woman’s vagina prior to ejaculation. This action intentionally frustrates the completion of the marital act and thus frustrates openness to life. (It is generally very ineffective as a method of birth control because it is likely some sperm will leak into the vagina prior to ejaculation.)

Barriers and devices also are direct physical actions to prevent the natural completion of the marital act. These include condoms, diaphragms, spermicides, and vaginal sponges. Aesthetically, these devices require a couple to act as if they are gearing up for war rather than preparing for what should be a complete gift of themselves to their spouse through marital intercourse. All of these produce multiple side effects, from allergies to bladder infections to toxic shock syndrome (from sponges).

No barrier methods are as effective as NFP as a means of postponing a pregnancy.
