Which thermometer is best to use for taking my basal body temperature (BBT)?

At the Fertility and IVF Acupuncture Clinic it is recommended you use a mercurial thermometer. Dr Wilson has noticed there is less of a chance of an incorrect reading with mercurial thermometers. Since mercurial thermometers are no longer manufactured, ask your pharmacist for a digital thermometer specifically designed for BBT purposes.

In the past, some patients at the Fertility and IVF Acupuncture Clinic have used battery operated thermometers and as a result, they have ended up with inaccurate BBT charts. The battery operated thermometers have two main shortcomings. Firstly, inaccurate readings when the batteries start to weaken, and secondly digital thermometers may have calibration problems. Both of these potential problems will mostly go unnoticed and will result in inaccurate BBT readings. If your digital thermometer is brand new, it is unlikely you will have a problem. If it is an older thermometer, consider buying a new one. Be mindful of the fact that an accurate BBT chart facilitates better treatment for your infertility.

The most important thing to remember with all the thermometers is to carefully read and follow the instructions. It sounds simple, but it is surprising how many people do not consider reading the instructions. As a result their temperature is taken incorrectly. Reading the instructions is especially important with a mercurial thermometer as you need to know how long it will take for the thermometer to produce an accurate reading.

If your BBT chart seems irregular, ask Dr Wilson and he will discuss potential thermometer issues with you during one of your consultations.
