Answer to Question 1

The perfect-use failure rate is the number of pregnancies (per 100 users) that will occur within the first year of use if the method is followed consistently and correctly. The typical-use failure rate is the number of pregnancies (per 100 users) that will occur within the first year of use if the method is not followed as outlined or it is used inconsistently.
