More about natural family planning.
When properly taught and practised, natural family planning can be a highly effective form of birth regulation. Recent studies indicate low failure rates of less than three pregnancies per 100 women years for couples with a strong motivation to follow the method. Studies show that pregnancy rates are high when the rules for avoiding pregnancy are not adhered to. Successful natural family planning can lead to heightened self esteem and marital enrichment.
