Most women are unaware of the user failure rate for hormonal contraception. Some studies indicate that the typical user failure rate for injectable contraception is about 4%.

The failure rate increases to 10% for oral hormonal contraceptives.

In the United States alone, 50-60% of all pregnancies are unplanned. The most common reasons for the high failure rate of hormonal contraception are incorrect usage and contraception failure, both of which can result in accidental ovulation.

Using the KNOWHEN® medical device to detect accidental ovulation while using hormonal contraception gives women the choice of taking immediate action to prevent a pregnancy.
