Ovulation thermometers
Basal thermometers help you determine the stages of your cycle and provide a tool for natural family planning problems.
A basal thermometer is a thermometer used to determine basal body temperature. Several natural family planning contraceptive methods, such as the temperature method or the symptothermal method, require measurement of the body's morning basal body temperature in a woman's menstrual cycle. The measurement of the basal body temperature can also be used to determine the fertile days around the time of ovulation if the woman wishes to have a child.
