BillingsMentor is an automated Web-based service for the Billings Method of natural family planning in which the guidance and interpretation previously communicated from teacher to student is provided by programmed algorithms. There are two functions: (1) to instruct the client to generate proper descriptions of her fertility symptoms; and (2) to interpret the symptoms efficiently according to the Billings Method and to communicate the results to the client. The efficiency of billingsMentor was tested by using the historical records of students who were under the guidance of a teacher to emulate their experience under the guidance of billingsMentor. The results indicate that billingsMentor performs as well as the teacher/student in recognizing the peak of fertility but it is slightly less efficient than the teacher/student in establishing the basic infertile pattern. Advantages that arise from adapting natural family planning to information technology are discussed.

The Natural Cycles app employs daily basal body temperature to define the fertile window via a proprietary algorithm and is clinically established effective in preventing pregnancy. We sought to (1) compare the app-defined fertile window of Natural Cycles to that of CycleProGo, an app that uses BBT and cervical mucus to define the fertile window and (2) compare the app-defined fertile windows to the estimated physiologic fertile window. Daily BBT were entered into Natural Cycles from 20 randomly selected regularly cycling women with at least 12 complete cycles from the CycleProGo database. The proportion of cycles with equivalent (±1 cycle day) fertile-window starts and fertile-window ends was determined. The app-defined fertile windows were then compared to the estimated physiologic fertile window using Peak mucus to estimate ovulation. Fifty seven percent of cycles (136/238) had equivalent fertile-window starts and 36% (72/181) had equivalent fertile-window end days. The mean overall fertile-window length from Natural Cycles was 12.8 days compared to 15.1 days for CycleProGo (p < 0.001). The Natural Cycles algorithm declared 12% to 30% of cycles with a fertile-window start and 13% to 38% of cycles with a fertile-window end within the estimated physiologic fertile window. The CycleProGo algorithm declared 4% to 14% of cycles with a fertile-window start and no cycles with a fertile-window end within the estimated physiologic fertile window. Natural Cycles designated a higher proportion of cycles days as infertile within the estimated physiologic fertile window than CycleProGo.
Use of cervical mucus in addition to BBT may improve the accuracy of identifying the fertile window. Additional studies with other markers of ovulation and the fertile window would give additional insight into the clinical implications of app-defined fertile window differences.
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.
The following is an address presented to a summit meeting on natural family planning sponsored by the Pontifical Councilfor the Family in December, 1992
I am honored and privileged to have this opportunity to be with all of you at this summit meeting on natural family planning. I wish to thank Alfonso Cardinal Lopez Trujillo for his invitation and all ofthe members ofthe Pontifical Council for their generosity and hospitality.
I have been asked to discuss with you what has become known as the Creighton Model Natural Family Planning System. This system obtained its name from my personal association, in its early days of development, with Creighton University School of Medicine in Omaha, Nebraska. This discussion will be, by its very nature, a summary of work that has been done and work that is currently ongoing.
The Creighton Model is referred to as a "model" as opposed to a "method" because it is an integrated education, research and service oriented system which meets the demands of the allied health and medical professions in the field of natural family planning. This system was specifically built to accomplish accountability and competency through a strong professional infra-structure. At the same time, it has been built within the context of a Catholic ethical and moral service delivery framework. It uses a standardized modification of the Billings' Ovulation Method in accomplishing these goals.
I personally became involved in natural family planning with a research project I did as a senior medical student in 1968. As I investigated the salivary albumin concentrations in women during the course of their menstrual cycles, I was looking for a reported decrease in albumin around the time of ovulation. Unfortunately, a project which I had no doubt would solve the problems related to natural family planning (sic), proved to be not a very good idea. . .

Fertility awareness-based methods (FABMs) are evidence-based means of tracking observable biomarkers of a woman's fertility for the purpose of reproductive health monitoring and family planning. However, medical education regarding FABMs is limited. The purpose of this study was to examine the effect of a 4-week, two-part online elective on students' knowledge of FABMs, confidence in explaining and offering them to patients, and anticipated behaviors in future practice. The online elective, "FABMs for Family Planning and Women's Health," was delivered from August 2020 to May 2023. Students completed preand postknowledge surveys. Paired t tests and the Wilcoxon signed rank test were used for analysis of the data. A total of 571 students completed the elective, and 462 students completed both preand posttest surveys (response rate=81%). Students' knowledge of FABMs increased significantly. Posttest scores increased by a mean of 9.02 for Part A and 5.95 for Part B. We identified a significant increase in students' confidence discussing FABMs to avoid pregnancy, achieve pregnancy, monitor reproductive health, and address reproductive health concerns. At the completion of the elective, students were significantly more likely to offer FABMs as an option for most or all women. This online elective addresses the knowledge gap in FABMs and was effective in improving students' knowledge of FABMs and their confidence and willingness to offer these methods to patients for family planning and management of common women's health conditions.
