Breast skin temperature rhythms in relation to ovulation.

Breast skin temperatures have been monitored at 30-min intervals throughout wake-span for the whole or part of the menstrual cycle of women aged 20-37 years using both manual and automatic (chronobra) methods of measurement. Circadian breast skin temperature rhythms have been mathematically characterized and rhythm parameters assessed in relation to the estimated time of ovulation. Data generally indicate that there is a peri-ovulatory rise in breast temperature. Computer simulation and practical experiments, based on changes in the residual sums of squares from target values obtained for days in the cycle prior to ovulation, have indicated that this peri-ovulatory increase in temperature is possibly detectable within 24 h. The use of the chronobra and associated statistics may be of value in signalling the onset of the infertile phase of the menstrual cycle.

Attitudes toward the rhythm method in the Philippines.

Two sets of focus group discussions on the advantages and disadvantages of the rhythm method were carried out in the Philippines in 1980 and 1981. The first discussions were held among 30 women and nine men 21-40 years of age, and the second among eight women 25-35 years of age who had voluntary pregnancy terminations after the method had failed. Among the perceived advantages of rhythm were that it permits spontaneous intercourse on the safe days and has no bad side effects. Among the perceived disadvantages were that it is ineffective, especially for women with irregular periods, and it requires abstinence. The women who had had voluntary pregnancy terminations discussed their motivations and rationales and the methods that they had used. The information obtained from the discussions formed the basis for support materials that are now used throughout the country.

A diaphragm tampon applied to an ovulation method in a birth control system.

Gynaeseal is a re-usable diaphragm tampon made from latex which forms a unique cervico-vaginal seal and isolates menstrual loss. In a prospective study involving 80 women, Gynaeseal was offered in combination with the Billings Ovulation Method in an advised birth control system. This system included: use of the diaphragm tampon during the menstruation-fertile phase interphase; periodic abstinence during the overtly fertile phase of the cycle; and if extreme reliability was required, for a further 2 days after the Billings method 'rules' allow resumption of intercourse. The diaphragm tampon successfully complemented the Billings Ovulation Method with 44 women (60.4%) assessing the GOM System as being as good, or better than, currently available reversible methods. It functioned effectively as a tampon with 50% (31 women) stating that they used the product as a contraceptive. One woman claimed an unplanned pregnancy. No significant medical complications were recorded. The product has major advantages as a tampon: it is easily and accurately inserted because of the efficient applicator; it isolated menstrual loss within a collection chamber; it protects the cervix; and it facilitates sexual activity. Based on a minimum effective diameter (62mm), the diaphragm tampon does not interfere with the normal physiology of the vagina. There appeared to be no significant distortion of normal adult pelvic anatomy, and properly placed, no sensation of the diaphragm tampon's presence. Regarding insertion of the diaphragm tampon using the spiral-curved applicator: 31 women (42.5%) had little or no difficulty; 29 (39.7%) moderate difficulty; 13 (17.8%) experienced serious difficulty; and 7 (8.7%) were unable to use the product.

A biphasic basal body temperature record during pregnancy.

A case of biphasic temperature record is reported during the course of an ectopic pregnancy. Possible implications of this phenomenon may improve our understanding of the role of ovum transmigration and the endocrinological interaction of pregnancy with hormonal control of ovulation.

The modified mucus method in India.

The modified mucus method-Prajanan Jagriti (fertility awakening) is intended to serve the cultural needs of illiterate and semilliterate women. Over 10 months, 3003 women in northern India were taught the modified mucus method. There were a total of 42 pregnancies in 24,702 cycles for a Pearl index of 2.04. High effectiveness is attributed to the support that was provided to clients by the instructor.

Physicians' views of periodic abstinence methods: a study in four countries.

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.

Comparative evaluation of two methods of natural family planning in Columbia.

Results of a comparative study of the ovulation method (OM) and symptothermal method (STM) of natural family planning in Colombia are presented. Recruitment of volunteer couples began in August, 1976, and continued through December, 1978, during which time 566 couples were randomly assigned to one or the other of the two methods. The study included 3 to 5 months of training in the method assigned, after which the couples entered the follow-up phase of the study. They remained in follow-up until (1) they dropped out or (2) the study closed in June, 1979. Total dropout rates were high for both methods of natural family planning. One year after entry into the follow-up phase of the study, net pregnancy rates were 24.2% for OM users and 19.8% for STM users. Gross pregnancy rates were 29.2% for OM and 26.1% for STM. Differences in pregnancy rates between the two methods were not statistically significant.
