Calendar-based methods are not usually considered effective or useful methods of family planning among health professionals. However, new "high-" and "low"-tech calendar methods have been developed, which are easy to teach, to use, and may be useful in helping couples avoid pregnancy. The low-tech models are based on a fixed-day calendar system. The high-tech models are based on monitoring urinary metabolites of female reproductive hormones. Both systems have high levels of satisfaction. This article describes these new models of family planning and the research on their effectiveness. The author proposes a new algorithm for determining the fertile phase of the menstrual cycle for either achieving or avoiding pregnancy.

Fertility AwarenessCalendar-Based MethodsPilot StudiesStandard Days Method
Natural methods of fertility regulation are acceptable in most cultures. Many couples worldwide do not wish to use contraceptives or do not have access to them but wish to limit their family size or lengthen the time between births. Barriers to expanding use of natural family planning (NFP) methods include a lack of providers who can teach NFP and a lack of time to teach and follow couples during the initial months of NFP use. If simple yet effective methods of NFP are available, then NFP could be introduced to a wider audience. Recently, calendar rules have been revised that use a set interval to identify fertile days. These new rules provide better coverage of fertile days and require less abstinence than the rules traditionally used with the calendar method. One of these new rules is being field tested in a pilot study in Brazil. Couples are asked to abstain from day 9-19 (inclusive) of the menstrual cycle, using a beaded necklace (the 'collar') as a mnemonic device. Focus groups with the teacher-monitors and in-depth interviews with female and male users were carried out to evaluate the acceptability of the 'collar' method. A preliminary analysis of these focus groups and interviews from the first site is presented.
Fertility AwarenessMonitor vs MucusEstimation AccuracyFertility Monitor Protocol
The length of periodic abstinence, due to overestimation of the fertile phase of the menstrual cycle, is often a cause for dissatisfaction, discontinuation, and user error with natural family planning (NFP) methods. The objective of this research was to compare the length of required abstinence (ie, estimated fertility) and coital frequency between 2 NFP methods. This was an analysis of data from a 12-month prospective comparison study in which participants were randomized into either an electronic hormonal fertility monitor (EHFM) group or a cervical mucus monitoring (CMM) group-both of which included a fertility algorithm as a double check for the beginning and end of the estimated fertile window. The number of days of estimated fertility and coitus was extracted from each menstrual cycle of data, and t tests were used to compare the means of these 2 variables between the 2 NFP methods. The study involved 197 women (mean [SD] age 29.7 [5.4]) who used the EHFM to estimate the fertile window and 160 women (mean [SD] age 30.4 [5.3]) who used CMM to estimate the fertile window. They produced 1,669 menstrual cycles of data. After 12 months of use, the EHFM group had statistically fewer days of estimated fertility than the CMM group (mean [SD] days, 13.25 [2.79] vs 13.68 [2.99], respectively; t = 2.07; P = .039) and significantly more coitus (mean [SD] coital acts, 4.22 [3.16] vs 4.05 [2.88], respectively; t = 1.17; P = .026). The use of the EHFM seems to provide more objectivity and confidence in self-estimating the fertile window and using nonfertile days for intercourse when avoiding pregnancy.

Emerging research raises questions that synthetic oxytocin during childbirth may alter the endogenous oxytocin system and influence maternal stress, mood, and behavior. Endogenous oxytocin is a key component in the transition to motherhood, affecting molecular pathways that buffer stress reactivity, support positive mood, and regulate healthy mothering behaviors (including lactation). Synthetic oxytocin is widely used throughout labor and postpartum care in modern birth. Yet research on the implications beyond labor of maternal exposure to perinatal synthetic oxytocin is rare. In this article, we review oxytocin-related biologic pathways and behaviors associated with the transition to motherhood and evidence supporting the need for further research on potential effects of intrapartum oxytocin beyond labor. We include a primer on oxytocin at the molecular level.
Body LiteracyClinician Training and PerspectivesTitle X Clinic ImplementationProvider Barriers and Facilitators
Natural family planning (NFP) methods are effective for contraception with proper and consistent use. However, only 1% of patients at federally funded Title X family planning clinics select NFP as a contraceptive method. The goal of this study was to understand from clinicians' perspectives the barriers and facilitators to providing NFP methods. Six telephone focus groups were conducted with 29 clinicians from Title X clinics across the United States and Puerto Rico. A hermeneutic method was used to analyze data for related themes. The overarching theme from the study was that participants had a strong desire to teach their patients how their bodies work and to empower them to learn to control fertility. patient misinformation and misunderstanding about fertility; provider ideas about ideal types of candidates for NFP; inconsistent patient teaching strategies; and lack of time to teach NFP methods. There is a need for increased NFP training for providers and efficient NFP patient teaching strategies to meet the needs of patients with limited knowledge about fertility.
