Basal Body Thermometer

Definition - What does Basal Body Thermometer mean?

A basal body thermometer is an extra sensitive thermometer that can detect the slight changes in body temperature women experience during ovulation. A standard thermometer normally displays temperatures to the tenth of a degree, while a basal body thermometer registers to the hundredth degree.

FertilitySmarts explains Basal Body Thermometer

Most women have an average temperature between 96 an 99 degrees Fahrenheit. This temperature drops slightly then increases one half to one degree Fahrenheit during ovulation. This increase in temperature is related to an increase of progesterone that is release from the corpus luteum after ovulation.

Basal body temperature is the temperature of the body at rest. It is best taken immediately after waking in the morning, prior to undertaking any activity. Charting waking temperatures can be an effective method for tracking ovulation and is considered a component of fertility awareness.
