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.
