Billings ovulation method

Billings Ovulation Method is a form of natural family planning that was developed by Drs. John and Evelyn Billings of Melbourne, Australia. The method is based on the observation and charting of cervical mucus to determine a woman's fertility.

History

The Billings Ovulation Method was developed in the 1950s by Drs. John and Evelyn Billings. The couple were inspired to create a natural method of family planning after observing the lack of options available to Catholic couples following the Papal encyclical Humanae Vitae, which prohibited artificial contraception.

Method

The Billings Ovulation Method involves the woman observing and charting changes in her cervical mucus. The presence and consistency of this mucus can indicate the various stages of the menstrual cycle, including ovulation. By avoiding intercourse on days when fertile-type mucus is present, couples can avoid pregnancy.

Effectiveness

Studies have shown that the Billings Ovulation Method can be up to 99% effective in preventing pregnancy when used correctly. However, the method requires careful instruction and consistent charting, and its effectiveness can be reduced if these are not adhered to.

Criticism

Critics of the Billings Ovulation Method argue that it is not as reliable as other forms of contraception, and that it requires a high level of commitment and understanding from both partners. Some also argue that it is not suitable for women with irregular menstrual cycles.
