Calendar methods of fertility regulation: a rule of thumb.

"[Many] illiterate women, particularly in the third world, find [it] difficult to apply usual calendar methods for the regulation of fertility. Some of them are even unable to make simple subtractions. In this paper we are therefore trying to evaluate the applicability and the efficiency of an extremely simple rule which entails only [the ability to count] a number of days, and always the same way."

Late infertile days in early postpartum cycles.

Luteal phase abnormalities in early menstrual cycles after pregnancy have been shown to cause confusion in the practice of natural family planning (NFP) for some patients and to restrict severely the number of late infertile days available to others. The cause of the abnormalities is uncertain but appears to be related to the nursing status of the patient.

Contraception survey: Denmark 1988.

In 1988 a survey** was conducted in 1,033 women living in Denmark, whose ages ranged from 15 to 44 years. The main aims of the study were to identify the influence, if any, of demographic and socioeconomic factors on contraceptive use and to assess the women's knowledge of selected facts concerning their own fertility. The study's additional objectives were to gain insight into factors influencing communication on the subject of contraception, such as advice obtained from professional counsellors, general information dissemination and discussion between partners, and to investigate women's attitudes and opinions regarding contraceptive methods and their use. The results are discussed in relation to the findings of other studies on the use of contraceptives both worldwide and in a number of European countries. The Danish findings are also examined in the context of possible action to reduce the relatively high rate of legally induced abortions in Denmark.

Is the lactational amenorrhea method a part of natural family planning? Biology and policy.

The lactational amenorrhea method is a natural method of family planning for women who breastfeed their infants. The underlying physiology results in a natural suppression of ovulation, and the concomitant amenorrhea, induced by exclusive (or almost exclusive) breastfeeding. This in addition to the infant's age of 6 months or less and specific feeding pattern are the parameters used to identify the possible return of fertility. The lactational amenorrhea method provides at least 98% protection against pregnancy. Data from a recent multicenter study of breastfeeding support the use of the lactational amenorrhea method as a natural family planning method. The lactational amenorrhea method can be incorporated into natural family planning programs and teaching.

Fertility and contraceptive adoption and discontinuation in rural Kenya.

After a long period of slow progress, the recent uptake of contraceptive use in Kenya has been dramatic. This report describes adoption of a method and method switching and discontinuation among a cohort of married women aged 25-34 in two contrasting rural areas. A retrospective "fertility diary" completed by each woman provided information on spousal separation, reproductive status, and contraceptive use over a period of 46-48 months. Contraceptive prevalence rose rapidly over the period in both areas, with significant net adoption of injectables in both areas and of IUDs in one only. Method discontinuation was concentrated among users of pills, barrier methods, and "natural" methods, and only one-third of all discontinuations were voluntary. The wide differences between the two rural areas in contraceptive prevalence were not totally reflected in recent fertility levels, and the contribution of other proximate determinants of fertility, particularly postpartum amenorrhea and spousal separation, are discussed.

Epidemiological studies of natural family planning.

The prevalence of the use of natural family planning (NFP) can be estimated from sample surveys of married women in the reproductive ages (MWRA). Surveys in developed and developing countries during the past decade indicate that the prevalence of NFP use varies from 0 to 11%. In addition, if one considers NFP use in relation to other contraceptive methods, the percentage of all current contraceptors who use NFP varies from 1 to 35%. This suggests that NFP is an important method in certain countries. Pregnancy rates for NFP vary widely, but most reliable studies report 1-year life-table pregnancy rates between 10 and 25/100 woman-years. The Billings ovulation method consistently has higher pregnancy rates than the sympto-thermal method and NFP users generally have among the highest pregnancy rates compared to other methods. The major safety issue concerning NFP is the risk of adverse pregnancy outcomes associated with aged gametes. There are suggestions from a number of investigations that conceptions distant from ovulation have a higher risk of spontaneous abortion and a higher proportion of male births. The findings with respect to birth defects or multiple pregnancies are less consistent, although some studies have reported an increased risk of chromosomal anomalies.

Basal body temperature as a method of ovulation detection: comparison with ultrasonographical findings.

In 47 cycles with hormonal evidence of ovulation, the detection and timing of ovulation by basal body temperature (BBT) and by ultrasonographical observation are compared. The ovulation detection rate by ultrasonographical method proves to be considerably higher than by BBT criteria. The timing of the day of ovulation is evaluated, assuming that the ultrasonographical event of follicle disappearance represents ovulation. BBT criteria nadir, coverline and the eye-balling method show a very poor frequency distribution. The result of the FDHP method is a nearly symmetrical distribution, however, with a considerable range. We conclude that ovulation detection and timing by BBT are not reliable.

Perspectives of physicians in Sri Lanka on periodic abstinence.

Since physicians strongly influence both national family planning policy and individuals' contraceptive choice, a survey was conducted to learn about the perspectives of Sri Lankan physicians (n-100) regarding periodic abstinence methods of family planning (PA). Female doctors (28% of the sample) were twice as likely to have ever provided PA advice to their clients as their male counterparts. Providers of PA were more likely to have ever personally used this form of contraception than PA non-providers. Regardless of PA provider status, all physicians most frequently recommended pills, injectables and IUDs to their clients. They had very good knowledge of the temperature method. The scientific foundation of this method is studied in medical school, suggesting that if the other modern methods (Billings and sympto-thermal) were incorporated into medical school curricula, physicians might be more willing to discuss, refer or provide other modern, scientific forms of PA to their clients.

Natural family planning: suitability of the CUE method for defining the time of ovulation.

The purpose of this study was to compare the CUE method for family planning with the Ovulation Detection Method for defining the fertile phase of the menstrual cycle. We evaluated 42 cycles from 10 women in Monterrey, Mexico, who were monitored by basal body temperatures, urinary LH, pelvic ultrasound, and the CUE monitor. The fertile phase of the cycle was adequately defined in all cycles using the CUE method, and in 35 cycles (83.3%) by the Ovulation Method. Using our protocol, the period of recommended abstinence with the CUE method is 9 days and with the Ovulation Method 11 days. The CUE method accurately defines the fertile phase of the menstrual cycle, thus improving the predictability of ovulation for women who use natural methods of birth control.
