Fertility Monitors and How They Work



fertility monitor

If a woman does not know how to monitor her reproductive health, it may result in repeated failed attempts at becoming pregnant. To avoid the frustration, discouragement, and disappointment, a fertility monitor will be very useful in determining the best time in your ovulatory cycle to have intercourse. Fertility monitoring is ideal for couples struggling but not succeeding to conceive.

A fertility monitor is a battery-operated computerized device that analyzes hormonal levels in bodily fluids such as urine, sweat and saliva as ovulation approaches. The resulting hormone levels are shown on a digital display. Fertility monitors work different than ovulation tests, which work by detecting the surge in Luteinising Hormone (LH), which occurs approximately two days prior to ovulation. Rather, fertility monitors work by determining fertile days within each cycle, pinpointing two peak fertility periods, identifying up to five additional fertile days.

There are three common types of fertility monitors, using different samples to derive the results. Urine based monitors measure the level of luteinizing hormone in the urine; readings are stored and compared to subsequent results.Saliva based monitors measure salivary electrolyte levels, indicating whether an increase or decrease in estrogen levels is present. Finally, skin-based monitors measure the changes of electrolytic levels in sweat. Changes in the electrolyte levels in bodily fluids are affected by changes in estrogen and luteinizing hormone levels, and it is upon this principle that these monitors are based.

The following are examples of fertility monitors available on the market.
• Clearblue Easy: Using disposable urine test sticks, this product can identify up to six fertile days per cycle.

• Duo Fertility: When worn overnight, this armband thermometer is able to record over 20,000 temperature readings.With this many recordings, the device isable to pinpoint ovulation more accurately than other systems. Fertile days can be predicted with an accuracy of 99%.

• Ovacue: This fertility monitor measures the electrolyte composition of saliva to determine an upcoming ovulation. This fertility monitor comes with a vaginal sensor that aids in confirming the date of ovulation.

• Persona: This urine-based monitor is hand-held, using disposable urine test sticks to determine the upcoming date of ovulation.

• Cyclotest:This fertility monitor uses basal body temperature and displays the results on an LCD screen.This enables the user to see her entire menstrual cycle.To store the data offline, it is equipped with USB connectivity for easy download.

The retail cost for fertility monitors can range from $100 to $700 for a single electronic fertility monitor, not including consumable supplies such as urine sticks, which need to be purchased regularly. Despite expensive initial prices, these devices are designed to last for several years.

Certain drugs and medications have been known to affect the reliability, and validity of fertility monitor results. Misleading results may occur if you are using antibiotics, hormonal treatment, and fertility treatments.
