AbstractBasal body temperature (BBT) is the lowest body temperature in a 24-hour period. It is a predictable pattern to the menstrual cycle that will allow the women to estimate when they ovulate. Basal body temperature can be used as a way to predict fertility or as a part of a method of contraception, by helping the best days to have or avoid unprotected sex.
