Natural, Drug- and Hormone-free Method to Identify the Low and High Risk Days of Conceiving a Child
Designed for Maximum Ease of Use by Simple Urine Tests
The Persona monitor measures the 2 key fertility hormones (estrogen and luteinising) with a reliability of 94% to identify the days to have sex without using any contraception (green days) and the days with a high risk of becoming pregnant (red days).
During the first cycle of use you will be asked to test with Persona Test Sticks on 16 days. After your first cycle you will be asked to do a test on 8 days each cycle.
Persona is 94% reliable, if the instructions are followed and the monitor is the only method of contraception:
6 of 100 women, who are using Persona (for contraception) for one year, conceive a child because the result of the test is incorrect (monitor showing green instead of red day).
The device is supplied by 2 x AA batteries which last for 4-6 cycles due.
