OV Watch
Sernova's first commercial product brought to market was the PSC Fertility Monitor. The monitor set a new benchmark in family planning by providing a more reliable and user-friendly approach to natural, cycle-based fertility status measurement. The PSC Fertility Monitor is a non-invasive method of predicting ovulation and the fertile window of women through the measurements of sweat ion changes on the surface of the skin.

It is a small wristwatch-like device, containing an interactive microprocessor combined with a biochemical sensor allowing it to produce data that predicts the fertility status of the user (not-fertile, fertile or ovulating). The computed results can then be viewed on the LCD screen of the device and/or the user can be alerted via optional audio signals.

In 2004 Sernova (then known as Pheromone Sciences) sold the fertility monitor technology to HealthWatchSystems, Inc. of Sarasota , Florida . The monitor is now sold under the name OV-Watch and Sernova receives royalties on the net sales.
