RECTAL METHOD
Lubricate the tip of the thermometer with a
VAGINAL METHOD
Please seek guidance from your health care professional.
V. RECORDING BASAL TEMPERATURE
Please refer to the sample recording and blank temperature tracking charts enclosed. Prepare your chart following the example. Day 1 for each cycle is the first day of menstruation (your “Period”). Above the
VI. CARING FOR YOUR BASAL THERMOMETER
Wash the tip of the thermometer with warm (not hot) soapy water before and after each use. Or, wipe the area with isopropyl alcohol before and after each use. To ensure optimum hygiene use a “Digital Probe Cover” every time a temperature is taken.
CHANGING THE BATTERY

VII. THE FEMALE REPRODUCTIVE CYCLE
In order to understand the Basal Temperature Method it is helpful to review the basics of human female reproductive activity.
A. THE ROLE HORMONES PLAY IN OVULATION
At the beginning of each menstrual cycle, the pituitary gland secretes a hormone (FSH or Follicle Stimulating Hormone), that acts upon the ovaries to prepare for ovulation. As one or more follicles in an ovary prepare for ovulation, they secrete another hormone called estrogen, that prepares the uterus for pregnancy by causing the inner lining of the uterus to thicken. Estrogen also causes some glands in the cervix to secrete a mucus discharge that is necessary for fertility. This mucus changes the environment in the vagina to make it more favorable to sperm life and provides a medium in which the sperm move upward into the uterus. The mucus typically starts as a sticky substance. During the time of fertility, it becomes more liquid and plentiful usually attaining a consistency very similar to raw egg whites. Sometimes the mucus becomes so watery that it will no longer stretch like raw egg whites, but continues to produce sensations of lubrication or wetness at the outer lips of the vagina.
