Donna Saliva Ovulation Microscope is the reusable ovulation test - simply put a drop of saliva on the glass, allow it to dry and look for the unique 'Ferning' pattern.

Estrogen levels increase just prior to ovulation, the increased levels of estrogen are associated with an increased level of electrolytes (salts) in the saliva. When placed on the microscope and left to dry for a few minutes, the electrolytes form the classic ferning pattern which are visiable through the Donna Saliva Ovulation Microscope. You can see the ferning pattern on the full product description where we have included a picture for you to compare with.

The closer you become to your LH surge the more 'Ferns' you will see. The microscope comes complete with full instructions for use and a battery already fitted.
