A fertility thermometer is used by women to determine the date of ovulation – the release of a ripe egg from the ovary – and therefore the optimum time for conception. Most women’s body temperature fluctuates approximately one degree after ovulation. She can assess when this has occurred by keeping a daily record of body temperature. This is the 'temperature method' of fertility control. The thermometer measures temperatures from 35˚C to 39˚. The thermometer was more accurate than other clinical thermometers of the time because it measured temperatures to within 0.1˚C. It was easily available from high street chemists.
