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.
How does PERSONA work?
PERSONA works by monitoring the hormones that directly control your cycle.
The levels of these natural chemical 'messages' rise and fall as they regulate the various stages of your cycle. This makes it possible to identify the days around ovulation when you are at significant risk of becoming pregnant.*
The Test Sticks collect hormones from your first urine of the day and process them into information that can be read by the Monitor. The Monitor then reads, stores and uses this information to let you know whether you are at risk of becoming pregnant ('Red' Day) or free to make love without a contraceptive* ('Green' Day).
The egg usually only survives for up to a day, however it is possible for sperm to survive for several days inside your body around the time of ovulation. PERSONA takes into account both egg and sperm survival times.*
During the first month of use, PERSONA will ask for 16 tests (day 6 and days 9-23) in order to build up a complete picture of your individual cycle as quickly as possible. From then on it will only ask for a test on 8 days of each cycle.
*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.
