Using eight test sticks, the Persona ovulation monitor analyses two hormones (LH and E3G) in first void urine and shows non-fertile days. While Persona is the best-known contraception monitor, it is comparatively unreliable with a Pearl Index of 6.
Many couples use Persona successfully to become pregnant. Since the summer of 2012, Persona has come in elegant casing with a colour touchscreen including a cycle predictor and an integrated alarm clock. Another new function is the option to protect data with a password.
