London - Makers of the controversial contraceptive Persona launched a high-profile advertising campaign in a bid to allay fears about the natural method of birth control which has led to hundreds of unplanned pregnancies. Its half-page advert in eight national newspapers - starting today - outline the benefits of the computerised birth control kit which monitors a woman's menstrual cycle.
The British government has warned women not to use the product if an unplanned pregnancy was "completely unacceptable", as one in 17 women each year could become pregnant because the device wrongly identifies a fertile period.
