Many Kiwi women actively keep tabs on their ovulation - yet relatively few are able to accurately pinpoint their fertile window.
That's according to a new study in which just 13 per cent of women surveyed were able to identify their fertility window, despite a third reporting that they monitored their ovulation.
The senior author of the paper, just published in the Australian and New Zealand Journal of Obstetrics and Gynaecology, says health professionals themselves may need help in busting common myths around ovulation and conception.
In the Otago University study, a sample of 1034 women aged 25 to 50 living in southern New Zealand were asked to fill in a fertility questionnaire.
More women who had ever monitored ovulation correctly identified the fertile window, although the proportion was still low, at just 13 to 18 per cent.
