Still Going: the Cue II The Cue II is an earlier model in the Cue line, introduced in 1999. Cue II features the same sensitive electronics as the OvaCue for monitoring changes in your body. The Cue II uses Zetek's patented Electrolyte Method for measuring changes in the body associated with ovulation. With the Cue II, you record daily readings on a Cue Chart and interpret the pattern according to instructions. Keeping and interpreting a chart is not difficult, it just requires a little extra effort. Combining the vaginal sensor with either device allows you to completely define the fertile window. Cue Charts Users of the Cue II need to download Cue Charts and learn how to track and interpret their readings. This is explained in detail in the Owners Manual. In brief, the user plots a numeric reading on a Cue chart each day. About a week before ovulation, electrolytes such as sodium and potassium change markedly. It is this Cue Peak on the graph that announces the beginning of the ovulatory process. A few days after the Cue Peak, the luteinizing hormone (LH) in the blood increases and decreases very sharply over a period of 24 hours (the LH surge). As LH reaches its peak in the blood, there is a definite change in the reproductive tract which can be measured by the Cue vaginal sensor. Mucus secretion increases, and the electrolyte content of the mucus changes. This change causes a sharp, clear drop and increase in these readings. It is this nadir and subsequent rise that the Cue uses to confirm ovulation. A breakthrough in hormonal measurement  How do you identify that moment of peak fertility? The researchers at Zetek discovered a convenient and accurate way, measuring electrolytes in saliva. Your body prepares for ovulation with complex changes in the output of hormones. About a week before ovulation, a threshold of increasing amounts of estrogen is reached. At this time, one ovum is selected from among the many available in one of the two ovaries. This one ovum begins to grow and the uterus begins to be prepared to receive a possibly fertilized egg. At the same time, other hormones are changing the amounts of minerals like sodium and potassium (electrolytes) that are kept or discarded by the body. This is what produces the Cue Peak, a high point in the salivary readings of electrolytes that corresponds to the release of an egg. Place a Bid!
