• NFP methods support reproductive health. They are good for the body. The natural methods have none of the harmful side effects caused by contraception, especially chemical contraceptives (e.g., pill, injection, etc.). For the woman, NFP charting can even assist in the diagnosis of underlying medical problems. And, if a couple find they are having trouble conceiving, NFP information can help them pinpoint the most fertile time of the wife's cycle.
  NFP methods can be marriage strengthening. NFP relies on couple communication and behavior change. NFP methods require husband and wife to cooperate with each other in the most intimate area of their lives. During times of periodic sexual abstinence, husband and wife live a renewed courtship as they discover non-sexual ways to express their love for each other. On a practical level, husbands are encouraged to "tune into" their wives' cycles, and both spouses are encouraged to speak openly and frankly about their sexual desires, hopes for number of children, and prayerful discernment of God's will for their marriage.
  When living the NFP lifestyle, husband and wife learn that they have a shared responsibility for safeguarding God's gifts of human sexuality, marriage and family. They also grow in their understanding of God's will for their family size. NFP has the potential to make good marriages great!
