PDF download of the BBT chart used at the Fertility and IVF Acupuncture Clinic.


The basal body temperature (BBT) is an integral tool in treating infertility with acupuncture and Chinese herbal medicine. The BBT chart allows a better understanding of the timing and quality of the different phases within a menstrual cycle. The BBT chart simply graphs the body temperature of a fertility patient when the body is at rest. To maximize the effectiveness of a BBT it is imperative the fertility patient fills in the chart as per the requirements of the respective acupuncturist or Chinese medicine herbalist. Below is a list of instructions for fertility patients at the Fertility and IVF Acupuncture Clinic to insure your BBT chart is completed to our requirements.

Recording your temperature on the BBT chart:

  • Start a new BBT chart on the first day of bleeding (period). If your period starts before midday, then today is day one. If it starts after midday then, day one on the BBT chart will be tomorrow.
  • For a reliable and meaningful reading make sure you have had at least four hours of unbroken sleep. If you feel a poor sleep may affect your chart, mark it on your chart so this will not be forgotten during your next consultation.
  • Take your temperature immediately after you wake up each morning. Try your best to do this at the same time each morning. If you delay your reading, it may result in anomalies in your BBT chart.
  • At the IVF and Fertility Acupuncture Clinic we advise you use a mercury thermometer. They have a tendency to be more reliable. There are thermometers which are specifically designed for BBT readings. It will be easier to use one of these thermometers.
  • Make sure you read the instructions which accompany your thermometer and follow these instructions closely. This will ensure an accurate temperature reading.
  • You can either use your thermometer orally or vaginally. For convenience, orally is fine (a vaginal reading will only be necessary if you receive very inconsistent readings orally).
