Symtothermal Method (This ain't the Rhythm Method)

A 2004 German-based study showed the Symtothermal method of fertility tracking to be 99.6% accurate in identifying ovulation. Cyclotest is the only fertility monitor on the European market that allows you to use the Symtothermal method.


So what is Symtotermal fertility tracking? It's the practice of tracking your bodily symptoms, ie, cervical mucus or LH hormone, plus your BBT temperature to gain a precise understanding of your monthly fertile and infertile phases.


Because many methods and fertility apps are based on overgeneralizations or weak science, cycle tracking is often perceived as unreliable. Cyclotest fertility monitors change the rules of the game, so you can confidently make decisions based on absolute understanding of your body's cycle.
