Disease relevance of Natural Family Planning Methods

The estimated time of ovulation (ETO) was correlated with the day of defined postovulatory infertility in 66 hormonally normal menstrual cycles from 24 subjects for each of 15 different natural family planning methodologies [1].

High impact information on Natural Family Planning Methods

The present experimental models suggest that AY-25,205 or similar analogs could be potentially useful for a more reliable rhythm method of birth control in humans, by timing ovulation and narrowing the fertile period of the cycle [2].
Twelve natural family planning teachers (average age 34.6 years) observed their cervical-vaginal mucus, tested their urine for LH, and observed salivary and cervical-vaginal mucus ferning patterns (with the Lady Free Biotester) for two menstrual cycles [3].
A protective effect was found for women who had had a tubal ligation, for those who practised the rhythm method of birth control, and for women who breastfed [4].
An independent assessment of the CUE Monitor (Zetek, Aurora, Colorado) as an ovulation predictor was made with emphasis on its potential role in "natural family planning". The device provides a digital measurement of the electrical resistance of saliva and vaginal secretions [5].
A majority of women (68% or greater) responded accurately about the mechanism of action of condoms, abstinence, sterilization, and abortion, but a substantial percentage of women (between 19% and 57%) were uncertain about the mechanisms of action of oral contraceptives, intrauterine devices (IUDs), Depo-Provera, or natural family planning [6].

Gene context of Natural Family Planning Methods

Contraception--a look forward, Part I: New spermicides and natural family planning [7].
Studies to evaluate use-effectiveness and cost-effectiveness of natural family planning (NFP) were conducted in Liberia and Zambia. The Liberian programme provided uni-purpose NFP services to 1055 clients mainly in rural areas; the Zambian programme provided NFP services integrated with MCH to 2709 clients predominantly in urban areas [8].
