Persona
The Persona is a small computerised monitor that assesses your early morning urine samples for levels of two hormones LH and an oestrogen. Sixteen daily tests are usually required in the first cycle and eight after that. A red indicator indicates fertile days. First year failure rates are in the order of 6 per hundred women-years (Table13.1). One authority suggests that if sheaths are used from Day 1 until the first 'red' day, abstention through the red days and unprotected intercourse from the second 'green' day, failure rates of less than 3% could be expected.
Persona is 94% effective - if one hundred women use it and no other method then 6 would be likely to conceive in one year.
