Zetek: Company Overview

"Building beautiful families since 1983"

Zetek, Inc. was founded in 1983 for the purpose of bringing a product to market that would help women accurately identify their fertile window by predicting and confirming ovulation. After extensive product development and testing and FDA approval, the Cue Ovulation Monitor was made available to the general public.

The company manufactures all Cue products in its Aurora, Colorado facility and each one is tested, sanitiized and sealed, before it is shipped. Every Cue is guaranteed to be free from defects for one year after purchase.

Zetek holds a patent on the Electrolyte Method™ and the Cue™ family of devices that predict and confirm ovulation by measuring electrolytes in saliva and vaginal fluid. The OvaCue Fertility Monitor is the third generation product, preceded by the Cue and Cue II. All are based on the Electrolyte Method.
