The calendar rhythm method of natural family planning (NFP) is one of the most popular contraceptive methods in the Philippines. As a result, the Philippines has one of the highest NFP prevalence rates in the developing world. In recent years, family planning program officials have become increasingly interested in improving the practice of NFP, both by improving the quality of rhythm practice and by introducing newer, more accurate NFP methods. Over the years a substantial body of research data related to NFP practice in the Philippines has accumulated. This paper presents major findings from past research on NFP in the Philippines, discusses their implications for program management, describes current research, and suggests needs for future research.
A study of the knowledge, perceptions, and behavioral intentions of physicians regarding periodic abstinence (PA) methods was undertaken in Mauritius, Peru, the Philippines, and Sri Lanka. Most respondents considered PA to be useful, although even the PA providers prescribed mainly non-PA methods. Detailed knowledge of PA methods was not evident, but most physicians were willing to initiate general discussion about PA with patients. Physicians favored methods perceived as "scientific" and "modern," which primarily prevent pregnancy and secondarily avoid other health risks. When carefully presented as "scientific" and "modern," methods presented to medical audiences may find acceptance and be more likely to result in referral.

Fertility awareness-based methods (FABM) of family planning have increased in popularity in recent years. The effectiveness of various methods can vary substantially and can be user dependent. For various reasons, there is a bias in OBGYN physicians against the use of FABMs for family planning. However, once educated about the methods of FABMs, this bias improves. There is limited regarding the education dedicated to FABM use in residency. We hypothesized that the residency education obtained regarding FABMs would be insufficient in preparing resident OBGYNs in effectively counseling patients regarding FABMs. a 16-question survey was created via SurveyMonkey and was sent to all ACGME accredited OBGYN residency programs for distribution to current residents. The survey was administered from October 2023 to December 2023. 125 responses were collected. Less than 40% of residents received formal training in regards to FABMs. Respondents indicated they felt most comfortable describing the calendar method to patients (68% respondents agree or strongly agree when queried if they could describe the method). 79.5% of respondents could not describe mucus-only, hormone monitoring, or sympto-thermal methods of family planning. When questioned if they were prepared to counsel postpartum patients who refused contraception regarding FABM, 58% of respondents indicated they could not assist their patients. Despite increased use in recent years and multiple options for FABM use, resident education in the application and use of FABMs is lacking. Additionally, residents indicated they are most familiar with the least effective methods (calendar method) which would likely be a significant detriment to their patients.
### What you need to know Fertility awareness based methods of contraception are increasingly being used for pregnancy prevention.1 In the US, the proportion of contraceptive users who choose such methods has grown from 1% in 2008 to approximately 3% in 2014.12 Relative to other methods of pregnancy prevention, however, substantial misinformation exists around fertility awareness based methods of contraception, particularly about the effectiveness of specific methods and how to use them. Providers who offer family planning counselling can promote correct and consistent use of the chosen method by helping people find a method that best fits their individual lifestyle, preferences, and goals.3 This article aims to help clinicians counsel people about fertility awareness based methods for pregnancy prevention by explaining the different methods, the evidence base for their effectiveness, and practical considerations for use. Fertility awareness based methods are devised on the premise that sexual intercourse can only lead to pregnancy during approximately 6-9 days of the menstrual cycle, commonly referred to as the “fertile window” (or fecund window, box 1).5 …
Various fertility indicators are used by natural family planning methods to identify the fertile and infertile phases of a woman's menstrual cycle: mucus observations, cycle-day probabilities, basal body temperature readings, and hormonal measures of LH and estrogen. Simplified NFP methods generally make use of a single fertility indicator such as cycle-day probabilities (Standard Days Method) or mucus observations (Billings Ovulation Method). The Couple Bead Method integrates the two simplest fertility indicators, cycle-day probabilities and mucus observations, expanding its applicability to all women, regardless of cycle regularity and length. In determining cycle-day probabilities, the Couple Bead Method relies on a new data set from ultrasound-derived determinants of gestational age that more directly define the day of conception and the fertile window. By using a visual-based system of inexpensive colored beads, the Couple Bead Method can be used by couples of all educational and income levels. Lay Natural family planning methods provide education in regard to the signs of a woman's body which indicate if she is possibly fertile or not. Two important signs are the day of her menstrual cycle and her observations of bleeding and cervical mucus or dryness. The Couple Bead Method teaches a couple how to observe these signs and chart them with a system of colored beads. The Couple Bead Method can be used by women with regular or irregular cycles. The bead sets are inexpensive and consist of a length of plastic cord, colored "pony beads" and safety pins.
