Official title
Randomized Comparison of Two Internet Supported Natural Family Planning Methods
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this research study is to compare the effectiveness of two natural family planning (NFP) methods that are provided over the internet by the Marquette University Institute for Natural Family Planning. One of the NFP methods is the use of a hand held electronic hormonal fertility monitor. The other method involves the self-observation of cervical mucus to track fertility. Both of the methods will involve placing information about fertility into an online charting system that automatically displays the days of fertility and infertility. The investigators are also interested in the influence of mutual motivation by the woman and her partner in using these methods to avoid pregnancy. The investigators hypothesize that there will be lower unintended pregnancy rates among those couples who use the electronic hormonal fertility monitor and among those couples who have a strong motivation to avoid pregnancy.
