“…These effects may sometimes prevent implantation (a postfertilization effect) and could be in conflict with some women's beliefs or value systems [16][17][18][19]. A study conducted in several clinics in Utah and Oklahoma, (USA) showed that 53% and 74% of women responded "no" when asked if they would use a method that acts after fertilization or after implantation, respectively [20].…”

Objective: Some methods of family planning may occasionally work after fertilization or implantation. These effects may be important to some women. We explored Spanish women's attitudes towards these potential mechanisms of action of family planning methods.Study design: Cross-sectional study in a Spanish representative sample of 848 potentially fertile women, aged 18-49. Data were collected using a 30-item questionnaire about family planning. Logistic regression was used to identify variables associated with women's attitudes towards postfertilization effects.Results: The majority of women were married, held an academic degree and had at least one child. Forty-five percent of women would not consider using a method that may work after fertilization and 57% would not consider using one that may work after implantation. Fortyeight percent of the sample would stop using a method if they learned that it sometimes works after fertilization, increasing to 63% when referring to a method that sometimes works after implantation. Women who believe that human life begins at fertilization, those who believe it is important to distinguish between spontaneous and induced embryo losses and women who report having a religion were less likely to consider the use of a method with some postfertilization effects. Conclusion:The possibility of postfertilization effects may influence Spanish women's choice of a FP method. Information about mechanisms of action of birth control methods should be disclosed to women so that they can make informed choices.

“…Patients rightfully rely on their medical professionals to supply the information relevant to making informed decisions, but as already mentioned, the professionals themselves may lack sufficient knowledge. Dr. Larimore himself has said that he prescribed oral contraception for years as a primary care physician without really knowing how it works (Larimore and Stanford 2000).…”
