Contraception continues to be controversial politically it seems, judging from recent news. However, there are quieter revolutions in reproductive health occurring somewhat surprisingly in the field of natural family planning. The Georgetown University Institute for Reproductive Health recently announced the availability of a free app for the Two Day Method of natural family planning, which focuses on raising women’s awareness of their cervical secretions surrounding their most fertile periods. This simple, inexpensive method of family planning does not involve contraceptives except for the possible use of condoms during fertile days. It can be used by women with varying cycle lengths. It is not necessary for a woman to be able to distinguish between types and consistency of secretions, only to be alert to their existence during her cycle. (The instructions do provide information about those types of secretions that indicate infection, however.)
When used correctly the Two Day Method is 96% effective, with typical use it is around 86% effective. That means that no more than 5-14 per 100 women using this method will get pregnant if avoiding pregnancy is the goal. (It can also be used by couples hoping to conceive a child.) Although there are some obvious benefits to the Two Day Method, including its ease of use and the ability to avoid hormonal contraceptives or other types of contraception, there are some disadvantages as well. First, the woman has to remember to check her secretions regularly. She must also have a partner willing to abstain from sex during her fertile days or use condoms. The method by itself provides no protection against HIV or other sexually transmitted diseases.
The new 2Day Method app is available for free download to iPhones at the App Store. The results of the clinical trial on the method at Georgetown University were first published in Fertility and Sterility in 20004.
