Now, use your saliva to test if you are ovulating

London:  Researchers have developed a new lipstick shaped 'revolutionary' ovulation kit that uses saliva, rather than a urine sample to determine when a woman is fertile.Traditional fertility predictor kits use urine to test for an increase in lutenising hormone (LH) which takes place oneor two days before ovulation.[caption id="attachment_500209" align="alignleft" width="380"] Representative image.

But if small fern leaves appear on the lens, the woman is said to have two or three days until ovulation.A full pattern of fern leaves on the lens means the woman is ovulating at that moment. Fertility experts, however, have warned that saliva tests have a history of being unreliable."A study of saliva testing devices published in the Lancet found that 8/10 post-menopausal women and all 10 men testedpositive for ovulation," Jane Knight, Fertility Nurse Specialist at the Zita West Clinic said."They concluded that the saliva test is unreliable for predicting the fertile time and its use should be discouraged," Knight said.PTI
