Natural Family Planning Methods Research Articles

Current Medical Research

This issue of Current Medical Research (CMR) includes studies that provide evidence that use of natural family planning (NFP) can be helpful for subfertile couples wishing to achieve a pregnancy, the effectiveness of a method of NFP during breastfeeding, and the effects of using NFP on marital relationships. This review also includes evidence on predicting the sex of a baby by timing intercourse, evidence that brain injuries can be reflected in changes in the menstrual cycle, and that women prefer methods of family planning that have no side effects. The issue ends with an in-depth review of new technologies that aid in the use of NFP. Topics covered include subfertile couples, breastfeeding, marriage, predicting the sex of a baby, brain injuries, and new technologies.

Self-Monitoring of Fertility Hormones: A New Era for Natural Family Planning?

Natural family planning (NFP) methods have served many generations well, and in particular, the symptothermal or symptohormonal methods. The comparison of daily mucus and temperature records for individual cycles with daily hormone measurements, which is now possible, shows that some of the assumptions underlying NFP may not be completely accurate. The various methods are inadvertently depending on an element of chance, which, of course, cannot be known by the NFP user. However, it is statistically inevitable that such errors will result eventually in an unexpected pregnancy, and these discrepancies are the likely reason for the method failures. Further research and integration of home hormone measurements with NFP symptoms are needed. Summary: Traditional NFP methods, based on the observations of temperature, mucus, and luteinizing hormone, can work well. However, these data are sometimes difficult to interpret, and significant changes in the variables are sometimes "missing" from some cycles. Changes in these variables are elicited by the estrogen and progesterone released from the ovaries. It follows that the direct measures of events in the ovaries are the levels of estrogen and progesterone or their derivatives in blood or urine. Measurements of urinary derivatives of estrogen and progesterone can be used to monitor the ovaries directly and are clearer indicators than traditional NFP methods.

Use of Natural Family Planning (NFP) and Its Effect on Couple Relationships and Sexual Satisfaction: A Multi-Country Survey of NFP Users from US and Europe.

Birth control is a persistent global health concern. Natural family planning (NFP) comprises methods to achieve or avoid pregnancy independent of mechanical or pharmacological intervention. The sympto-thermal method (STM) of NFP employs daily observation of cervical fluids and measurement of basal body temperature. This multi-country study was undertaken to describe the characteristics of STM users, understand their perceptions of NFP, and its perceived impact on relationships. Questionnaires for women and men were developed in German and translated to English, Polish, Italian, Czech, and Slovak by native speakers. A total of 2,560 respondents completed the online questionnaire (37.4% response). Participants were married (89%) and well educated, and their self-perceived financial status was described as "good" or "very good" by 65% of the respondents. Forty-seven percent had previously used contraceptives. Ninety-five percent of women and 55% of men said using NFP has helped them to know their body better. Large majorities of men (74%) and women (64%) felt NFP helped to improve their relationship while <10% felt use of NFP had harmed their relationship. Most women (53%) and men (63%) felt using NFP improved their sex life while 32% of women and 24% of men felt it was unchanged from before they used NFP. Seventy-five percent of women and 73% of men said they are either "satisfied" or "very satisfied" with their frequency of sexual intercourse. This survey demonstrates STM of NFP is a well-accepted approach to family planning across several Western cultures. It is consistently viewed as being beneficial to couples' self-knowledge, their relationship, and satisfaction with frequency of sexual intercourse.

The effect of a drospirenone-containing combined oral contraceptive on female sexual function: a prospective randomised study

Objectives: The study investigated the effects on female sexual function of a progestogen-containing combined oral contraceptives (COCs) with an antiandrogenic profile taken in a continuous regimen.Methods: In this prospective randomised single-institution study, 80 healthy women with a monogamous partner and an active sexual life were randomised into two groups for a period of 3 months. Women in the exposed group (n = 40) took a COCs containing 30 μg ethinylestradiol (EE) and 3 mg drospirenone (DRSP) in a 21/7 regimen. Women in the control group (n = 40) used either a barrier contraceptive method (BCM) or a natural family planning method (NFPM). Participants were asked to complete a set of validated questionnaires to assess sociodemographic variables and measure Female Sexual Function Index (FSFI).Results: The total FSFI score (p < 0.0001), as well as the desire (p = 0.04) and arousal (p = 0.03) scores, were significantly lower in the COCs group after 3 months of hormonal contraceptive use compared with baseline. Women using BCM or NFPM showed an improvement in total FSFI score (p = 0.02). Hormonal contraception with DRSP increased the likelihood of worse sexual function in the desire (odds ratio [OR] 2.47; 95% confidence interval [CI] 1.22, 4.98; p = 0.01) and arousal domains (OR 2.85; 95%CI 1.34, 5.93; p = 0.005) and in total FSFI score (OR 2.01; 95%CI 1.45, 2.79; p < 0.001). The results remained statistically significant even after adjustment for smoking status.Conclusions: The study found evidence that women taking a combined EE/DRSP COCs for 3 months may have a worsening of sexual function as measured by FSFI.

Monitoring of ovarian activity by measurement of urinary excretion rates using the Ovarian Monitor, Part IV: the relationship of the pregnanediol glucuronide threshold to basal body temperature and cervical mucus as markers for the beginning of the post-ovulatory infertile period.

Do the basal body temperature (BBT) shift and the cervical mucus markers for the beginning of the post-ovulatory infertile phase (POIP) of a menstrual cycle agree with the corresponding urinary pregnanediol glucuronide (PdG) threshold value? Perfect agreement between the cervical mucus markers and BBT shift and the hormonal definition of the start of post-ovulatory infertility occurred for only 7-17% of the cycles. The PdG threshold of 7.0 µmol/24 h is an objective and accurate marker for the beginning of the POIP. The rise in serum progesterone also produces the BBT shift and changes in cervical mucus which determine the mucus peak. Serum progesterone and urinary PdG are closely correlated when variations in urine volume are taken into account. Individual menstrual cycle profiles of urinary PdG excretion rates for 91 fertile cycles from normally cycling women were analysed to identify the day of the beginning of the POIP. These days were compared with those determined by the day of the BBT shift +2 days, the day of the mucus peak +4 days and the later of these two indicators. The study lasted 3 years. A total of 62 women with normal menstrual cycles were recruited from three centres: Palmerston North, New Zealand; Sydney, Australia and Santiago, Chile. The cycles were displayed individually in a proprietary database program which recorded the PdG excretion rates, the BBT shift day and the cervical mucus peak day. A group of 15 women from a separate Chilean study had PdG urinary data measured as well as their day of ovulation determined by ultrasound. The BBT and cervical mucus markers differed significantly in their identification of the beginning of the POIP when compared with the PdG excretion rate of 7.0 µmol/24 h. The observation that the BBT shift day and the mucus peak day could be identified even though the PdG excretion rates were still at baseline levels in some cycles could lead to an unexpected pregnancy for women using these natural family planning (NFP) indicators. The study consisted only of fertile cycles from women with regular cycles of 20-40 days duration. All the women were intending to avoid a pregnancy during the study, thus the limits of the fertile window were not tested. The NFP signals occurring earlier than the PdG threshold day could lead to an unexpected pregnancy. The signals occurring on the same day or later than the PdG threshold would not lead to unexpected pregnancies, but would require extra abstinence that could lead to non-compliance with the NFP method. A possible improvement in reliability of NFP methods is suggested. This study (project #90905) was funded by the NDP/UNFPA/UNICEF/WHO/World Bank Special Programme of Research, Development and Research Training in Human Reproduction (HRP). D.G.C. currently works for a diagnostic development company, Science Haven Ltd. The other authors have nothing to declare.

Opinie studentów nauk o rodzinie na temat metod planowania rodziny

The transmission of life is associated with a particular responsibility, including, among other things, making the right choice of the method of family planning. Moral rules in the sphere of procreation are presented in documents of the Church, especially in the encyclical Humanae Vitae. Those texts present morally accepted methods of family planning as methods of recognising fertility and not counteracting it. Today, however, many secular and liberal sources promote using contraceptives. There is a need for advisers who can indicate the misconceptions of such a choice and help in accepting natural family planning as a lifestyle. The students of the John Paul II Catholic University of Lublin are educated within the scope of family sciences and have the family planning exercises in their curriculum. Before starting the course questionnaire surveys were conducted, and after finishing it, we have noticed favourable changes in the attitude towards the methods of family planning. In 2011, 93% of the student participating in the course confirmed that their attitude towards the methods of family planning had changed to more favourable one under the influence of the course exercises. After finishing the course in the academic year 2012/2013, the percentage of the students deeming use of contraceptives as morally unacceptable dropped from 43.4% to 19.2%, and the percentage of the students expressing the opposition to them grew from 55.3% to 80.8%. In accordance with John Paul II's appeal expressed in his Exhortation, Familiaris Consortio, there is a need for “wider, more definite and systematic effort leading to recognition, evaluation and use” (FC 35) of the methods of natural family planning.

BillingsMentor: Adapting natural family planning to information technology and relieving the user of unnecessary tasks.

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.

Cohort Efficacy Study of Natural Family Planning among Perimenopause Age Women

To determine the efficacy of using natural family planning (NFP) methods to avoid unintended pregnancy among women of perimenopause age (i.e., age 40-55 years). A secondary analysis of subset data from two prospective observational cohort studies. A university based in-person and online NFP service program. One hundred and sixty couples who used either a website or an in-person NFP service to learn how to avoid pregnancy from January 2001 to November 2012. A prospective 12-month effectiveness study among 160 women (between ages 40-55) who used NFP to avoid pregnancy. The women used either a hormonal fertility monitor, cervical mucus monitoring, or both to estimate the fertile phase of their menstrual cycles. Survival analysis was used to determine the pregnancy rate over 12 months of use. There were a total of five unintended pregnancies among the participants. The typical use pregnancy rate was six per 100 women over 12 months. The monitor alone participants (n = 35) had a 12-month pregnancy rate of three, the participants (n = 73) who used mucus alone had a pregnancy rate of four, and the participants (n = 42) who used the fertility monitor plus mucus had a pregnancy rate of six. Natural family planning methods can be effective for older women to avoid an unintended pregnancy with correct use and adequate instructions. The pregnancy rate most likely was affected by diminished fertility and motivation to limit family size.

Influence of Motivation on the Efficacy of Natural Family Planning

To determine the influence of mutual motivation on unintended pregnancy rates of couples who used natural family planning (NFP) methods to avoid pregnancy. Using an online taught NFP method, 358 women and (their male partners) indicated "how much" and "how hard" they wished to avoid pregnancy on a scale of 0 to 10 before each menstrual cycle charted over 12 month of use. This motivation scale is used in the National Survey of Family Growth as a measure of motivation. All pregnancies were verified with an online pregnancy evaluation and urine-based pregnancy test. A combined motivation score was used in analysis. There were 28 pregnancies among the low-motivation participants (N = 60) and 16 among the high-motivation participants (N = 298). At 12 months of use, there were 75 pregnancies per 100 users for the low-motivation group and only 8 for the high-motivation group. There was an 80% greater likelihood of a pregnancy with the low-motivation group (χ = 25.5, p < .001, odds ratio = 1.80; 95% confidence interval = 1.61-1.90). High motivation to avoid pregnancy by both the female user of a behavioral method of family planning and her male partner is required for high efficacy. Assessing motivation of both the woman and her male partner before prescribing NFP methods is recommended.

Spiritual Care of Couples Practicing Natural Family Planning.

There are few studies that have investigated the spiritual problems of couples practicing natural family planning (NFP). The purpose of this paper is to analyze the spiritual problems and interventions of couples who were taught NFP by means of a professional online Web-based support system. Responses from this online system and its forums were categorized according to spiritual responses, spiritual problems, and spiritual interventions to the practice of NFP. Themes addressed included spiritual care in regards to decisions about the transmission of new life, difficulties in dealing with chastity and abstinence, bioethical problems related to pregnancy and illness, end of the reproductive life decisions, ethical treatment of women's health problems, sacrifice, and personal and relational struggles. Online community support, help in building confidence in NFP methods, and bioethicist referral are key interventions. The complexity of these spiritual responses, problems, and appropriate interventions require the expertise of health professionals in cooperation with bioethicists. We concluded that NFP can be viewed as both a spiritual practice and a means of spiritual growth.

Challenges faced by older women in Botswana in accessing services that address sexual and reproductive health, and family planning needs, in Botswana

AbstractObjective: This study explored the challenges that older women from selected sites in Botswana face in accessing services that address sexual and reproductive health (SRH) and family planning (FP) needs.Design, setting and subjects: Two rural and two urban health districts were randomly selected for the study. A statistically determined sample of 454 older women was allocated to the different districts (strata), using probability proportional to size.Outcome measures: The study estimated the percentage use of sexual and reproductive health services (including family planning services), unmet need for family planning and factors inhibiting use of these services.Results: The study revealed that 25% of the older women used some type of FP method. Of this number, 67.9% were aged 50–59 years, 17.4% 60–69 years, 10.1% 70–79 years, and 72% had unmet needs for FP. The older women used natural FP methods mainly. The main SRH services used by them were screening for human immunodeficiency virus/acquired imm...

Clinician Perceptions of Providing Natural Family Planning Methods in Title X Funded Clinics

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. Four subthemes emerged: 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.

Natürliche Familienplanung

Due to new and further developments, the field of natural family planning methods has become confusing. The conventional nomenclature—the temperature method, the Billings method, the symptothermal method—includes numerous variations of natural methods that vary substantially in efficacy, practicability, and acceptability. The new name of the evidence-based symptothermal method of the German working group NFP (Natural Family Planning) is sensiplan® (www.sensiplan.eu), which has a proven high efficacy rate. Women can reliably and independently determine the fertile window of their individual cycle without much effort. Thus, this method can be used for family planning and differentiated monitoring of a woman’s cycle.

Natural Family Planning in Education and Practice

Natural family planning (NFP), which comprises multiple, variegated methods, is an underutilized form of birth control. This is despite women's interest in it. It is unclear why this is the case. One hypothesis is that nurses and physicians, main sources of information on reproductive health matters, are not adequately trained to provide NFP services to patients. The extant English language literature on the subject of NFP and professional education was examined and analyzed for information on the breadth, content, and depth of NFP teaching in medical and nursing programs. Data on physicians’ and nurses’ practice and attitude toward NFP were also examined. Few articles and limited data exist to indicate what type of training in NFP student doctors and nurses receive, though it is clear that some information about it is obtained through the undergraduate nursing or medical curriculum. The literature suggests that many health-care providers would offer an NFP method to specific patients, but that such opportunities are rarely sought and are in fact limited. These methods would be more widely used if health-care professionals in general had better and more adequate training in NFP and offered it to more of their patients. Catholic professionals in particular have a special responsibility to train users and teachers of NFP.

The Life and Times of John J. Billings: The Mucus Symptom, a Physiologic Marker of Women's Fertility

Dr. John J. Billings died on April 1, 2007, after a long illness. Prior to his death he had been awarded the President's Medal by Georgetown University in recognition of his research in developing the Billings Ovulation Method of natural family planning. However, he was personally unable to accept the award due to his failing health. This paper is a biographic sketch of his long and illustrious career.

Natural Family Planning: Physicians’ Knowledge, Attitudes, and Practice

ObjectiveTo assess physicians’ knowledge, attitudes, and practice with respect to four evidence-based natural family planning (NFP) methods: Standard Days, cervical mucus, basal body temperature, and the lactational amenorrhea method. MethodsWe undertook a cross-sectional survey of a random sample of family physicians and all gynaecologists in British Columbia (n = 460) who have women of reproductive age in their practice, as well as all affiliated residents (n = 239). Main outcome measures were (1) physicians’ attitudes towards NFP and their perceptions of its effectiveness; (2) the relationship between physicians’ demographic factors, their personal experience or beliefs, and their attitudes and knowledge; and (3) how these factors affect the counselling physicians offer their patients. ResultsThe survey response rate was 44%. Only 3% to 6% of physicians had correct knowledge of the effectiveness in perfect use of the NFP methods cited in this study. Fifty percent of physicians who responded mention NFP to their patients as an option for contraception, and 77% of physicians mention NFP as an option to couples trying to conceive. Family physicians and residents were much more likely than gynaecologists or gynaecology residents to mention NFP during counselling. Older physicians were more likely to mention NFP than younger physicians and also had more personal experience with NFP. ConclusionMost physicians in our study underestimated the effectiveness of NFP methods, and only a small proportion of physicians provide information about NFP during contraceptive counselling. Physicians need better understanding of modern methods of NFP to provide evidence-based contraceptive counselling to selected highly motivated patients who prefer NFP as a contraceptive choice.

Efficacy and Efficiency in Natural Family Planning Services

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.

Efficacy of Cervical Mucus Observations Plus Electronic Hormonal Fertility Monitoring as a Method of Natural Family Planning

To determine the effectiveness of an electronic hormonal fertility monitor plus cervical mucus monitoring to avoid pregnancy. A 12-month prospective clinical efficacy trial. One hundred ninety five (195) women (mean age 29.8 years) seeking to avoid pregnancy with a natural method at 5 clinical sites in 4 cities. Each participant was taught to track fertility by self-observation of cervical mucus and an electronic monitor that measures urinary levels of estrone-3-glucuronide and luteinizing hormone. Correct- and typical-use unintended pregnancy rates. There were a total of 26 unintended pregnancies, 3 with correct use. With 1,795 months of use, the correct-use pregnancy rate was 2.1% per 12 months of use (i.e., 97.9% effective in avoiding pregnancy when rules of the method were always followed) and the imperfect-use pregnancy rate was 14.2% per 12 months of use (i.e., 85.8% effective in avoiding pregnancy when rules of the method were not always followed and all unintended pregnancies and months of use were included in the calculations). Correct use of an electronic hormonal fertility monitor with cervical mucus observations can be as effective as other fertility awareness-based methods of natural family planning. Comparative studies are needed to confirm this conclusion.

Knowledge, attitude and practice of natural family planning methods in a population with poor utilisation of modern contraceptives

SummarySub-Saharan Africa has one of the highest fertility rates in the world, which is further promoted by the low utilisation of modern contraceptive methods. Yet, many communities claim to have traditional methods of family planning that pre-date the introduction of modern contraceptives, implying that contraception is a culturally acceptable norm. It was therefore postulated that the study population would have a high level of awareness and practice of natural methods of family planning. We aimed to obtain an insight into the extent and correctness of knowledge about natural family planning methods, and its practice as a guide to the general acceptance of contraception as a concept. Pre-tested structured questionnaires were administered to women of childbearing age in households properly numbered for primary healthcare activities. The level of awareness of natural family planning methods was significantly less than awareness for modern methods of contraception. The awareness rate for rhythm method, lactational amenorrhoea method and coitus interruptus was 50.7%, 42.1% and 36.1%, respectively. For all three national family planning methods, there is a steady decline between awareness, correct description of method and utilisation, a difference that was statistically significant in all cases. The sociodemographic factors of the responders had varying influence on utilisation of all three natural family planning methods studied. Rural dwellers practised the lactational amenorrhoea method significantly more often than urban dwellers. Significantly more Muslims than Christians with four children or more practised coitus interruptus or the rhythm method, while the use of lactational amenorrhoea method was significantly increased with the number of living children in both religious groups. There is a relatively low level of awareness of natural family planning methods in the study population, poor utilisation and wrong use of methods. Therefore, improving the correct level of information on natural family planning methods is likely to improve the use of both natural family planning and modern contraceptive methods.

The Future of Professional Education in Natural Family Planning

Nurses and other health care professionals often have little knowledge of methods of natural family planning (NFP) and do not readily prescribe natural methods for their patients. One reason for this is that little or no information on NFP is provided in nursing or medical schools. The holistic, informational, and integrative nature of NFP fits well with professional nursing practice. A university online distance education NFP teacher training program, which offers academic credit and includes theory, practice, and the latest developments in fertility monitoring, has been developed for health care professionals. Professional NFP services in the United States need to meet worldwide standards and include documenting and assessing pregnancy outcomes, tailoring NFP services to the client or couple, and simplifying them for ease of use in a standard health care practice.
