Natural family planning. Demand is increasing

Efficacy and Efficiency in Natural Family Planning Services

Fehring RJ, 2009 · Linacre Q ·

Relatively few Catholic couples in the United States use modern methods of natural family planning (NFP). So too, few Catholic physicians and health professionals prescribe the use of NFP methods for their patients. Reasons for low use of NFP methods include their perceived low efficacy; the complexity of learning, using, and teaching these methods; and the prolonged (and often unnecessary) required abstinence. Newer and simplified methods of NFP have been developed by physicians and scientists that are less complex and use modern technologies of detecting fertility and communicating instructions. Catholic physicians and scientists need to continue to answer the call by the Holy Fathers (from Pius XII to Benedict XVI) to develop secure and scientifically sound methods of NFP.

Response to “The illusion of reproductive choice: how restorative reproductive medicine violates reproductive autonomy and informed consent”

Stanford JB et al., 2026 · Fertility and sterility ·

Peipert et al. (1) claim that restorative reproductive medicine (RRM) originated as a political and religious movement with the purpose to limit access to in vitro fertilization (IVF). In so doing, they mischaracterize the origin, development, and aims of RRM, as articulated by the International Institute for Restorative Reproductive Medicine, founded in 2000. They do not refer to any peer-reviewed medical literature published by clinicians and researchers working to develop RRM. Objecting that certain political or economic interests promote RRM (or, alternatively, IVF) does not constitute the basis for an evidence-based scientific critique or discussion. Thus, their editorial falls short of a serious effort to understand RRM scientifically.

Pregnancies, intentions, and fertility behaviors during use of the Creighton Model FertilityCare System after initial intention to avoid pregnancy: Results from the Creighton Model effectiveness, intentions, behaviors assessment study

Stanford JB et al., 2025 · PLoS One · Open Access

Knowledge of the fertile and infertile phases of the menstrual cycle can be applied to conceive or to avoid pregnancy. Fertility intentions and sexual behaviors during the fertile time may influence whether and when pregnancy occurs. The Creighton Model FertilityCare System (CrMS) is a specific system of fertility appreciation used to conceive or to avoid pregnancy. The objective of this paper is to report intentions, behaviors, and pregnancy rates during use of the CrMS among couples who initially intended to avoid pregnancy.Data and methodsWe analyzed a prospective cohort study conducted in 17 CrMS centers across the USA and Canada, following 296 couples for up to one year after onset of initial use of the CrMS to avoid pregnancy. Baseline data included demographics, motivations, and pregnancy intentions for each partner. Couples contributed 2894 menstrual cycles, most of which had data collected (by questionnaires and daily diary) on cycle-specific pregnancy intentions, days of potential fertility, and fertility behaviors. Pregnancies were prospectively actively ascertained. We found a high concordance (91%) in cycle pregnancy intentions between partners. However, 44% of cycles with strong intentions to avoid pregnancy included intercourse on potentially fertile days or days of undetermined fertility status. Across all sensitivity scenarios, cumulative 13-cycle pregnancy rates with cycle intention to conceive ranged from 88.0% to 89.8%, and cumulative 13-cycle pregnancy rates with cycle intention to avoid ranged from 29.1% to 35.3%. In multivariate analysis, baseline motivations and intentions for pregnancy within 2 years were strongly correlated with the likelihood of pregnancy, more so than cycle intentions. The findings suggest that in some populations using natural family planning, baseline motivations and intentions may be more strongly related to pregnancy rates than cycle intentions. Our findings also highlight essential elements for evaluating correct use, including complete recording of intercourse and its timing.
