PERSONA offers women the choice of a natural method of contraception, working in harmony with their bodies. It works non-invasively by monitoring hormone levels in urine. This method of contraception is ideally suitable for women in stable relationships who intend to have children in the future and who have regular cycles between 23 and 35 days in length. PERSONA consists of a small hand held monitor and simple, disposable urine test sticks. During the testing, these sticks collect hormones from the urine and convert them into information that the monitor is able to interpret. A green or red light on the monitor then indicates whether the user is free to make love without a contraceptive*. Complete starter kit containing the Persona monitor, and one month's supply of test stick.
