PERSONA is a method of contraception that works in harmony with your body.
It works by monitoring the changes in hormones (luteinising hormone and estrogen) which control your cycle and identifies the days when you are at significant risk of becoming pregnant.
PERSONA consists of Test Sticks and a hand-held Monitor.
The Test Sticks collect hormones from your first urine of the day and process them into information that the Monitor can read.
The Monitor reads, stores and uses the information from the Test Sticks to let you know whether you are at risk of becoming pregnant (‘Red’ Day) or free to make love without a contraceptive* (‘Green’ Day).
Through its coloured Lights and Display Screen your Monitor tells you your contraceptive status.
*Based on independent trials PERSONA is 94% reliable when used according to the instructions and as the only method of contraception. This means that if 100 women use PERSONA for one year, 6 are expected to become pregnant as a result of sex on a Green Day due to PERSONA incorrectly identifying their fertile days.
