Body temperature measured immediately after waking in the morning. In women, regular measurement of the basal body temperature provides information on the time of ovulation and can be used, for example, for natural family planning and for the diagnosis of menstrual disorders.

the temperature obtained upon awakening and before physical activity has begun

body temrperature; often used in charting ovulation

A woman's body temperature when taken at its lowest point, usually in the morning before getting out of bed. Charting BBT is used to predict ovulation.

Your body temperature at rest as measured with a special Basal Body Temperature thermometer. A rise in BBT occurs after ovulation making BBT the only fertility sign that is useful for pinpointing the actual day of ovulation.

Just before ovulation, a woman's basal (resting) temperature increases. The temperature should be taken early in the morning, which is usually the lowest temperature of the day to time intercourse to increase the likelihood of conception.

The temperature of your body first thing in the morning upon first awakening. The BBT pattern can help determine when ovulation (the monthly release of an egg from the ovary when you are most fertile) occurs

the lowest body temperature during the day (usually early morning). For a woman, the BBT has a pattern of being lower than normal prior to ovulation and higher than normal after ovulation.

body temperature in the morning before rising or moving about or eating anything

Temperature reading at rest used for detection of ovulation.

The body temperature taken orally, vaginally or rectally, usually after a rest and before any activity. Known as BBT.

A means of dtermining the time of ovulation based ondaily fluctuations in a woman's body

(BBT) test - The temperature of the woman taken every morning during a cycle before any activity is done that may raise her temperature. It is done to help determine if ovulation has taken place

The body temperature taken at its lowest point of the day, typically in the morning before getting out of bed.

A temperature monitored by women attempting to ascertain the best time to try for pregnancy. When a woman ovulates, her basal body temperature will normally rise half a degree. By monitoring her temperature every morning, a woman can determine when she is ovulating.

The temperature of the body at rest, taken immediately on waking, before any activity.

The temperature taken in the morning before getting out of bed, for the purpose of documenting a rise in temperature which is consistent with ovulation.

the woman's temperature, taken either orally or rectally, which is used to help determine ovulation

The core body temperature. Normal body temperatures can range from 96°F to 98°F but will increase by half a degree to one full degree when a woman ovulates. Women can measure their basal body temperature daily to determine when they are ovulating.

temperature of a person's body taken first thing in the morning after several hours of sleep and before any activity, including getting out of bed or talking; often charted to determine the time of ovulation.

the temperature of the human body at rest, unaffected by activity.

The temperature of the woman, taken either orally or rectally, upon waking in the morning before any activity. Used to help determine ovulation.

The temperature of your body upon first waking up in the morning. The basal body temperature rises by about 1/2 to 1 1/2 degrees around ovulation, which is how many women determine when they're fertile.

A temperature reading that can be used to chart ovulation when taken every day.

(BBT) - Your base body temperature - that is, before movement, caloric consumption or anything else is factored in.

The body temperature of a person recorded immediately upon awakening, before any activity is undertaken. The temperature can be taken orally or rectally. The temperature is recorded daily on a graph, which can show some evidence of ovulation.

The temperature of your body at rest. Best taken upon waking after at least three hours' sleep and before any activity at all. Find out more about charting temperatures.

the temperature taken at its lowest point in the day, usually in the morning before getting out of bed

BBT) The body reaches a basal metabolic temperature early in the morning when we are at rest. Charting this temperature variation helps determine when ovulation occurs. The basal body temperature is measured with a special basal thermometer. For more information, see http://www.epigee.org/guide/nfpchart.html.

This is essentially the body's resting temperature. By taking and recording your basal body temperature on a daily basis, you can monitor changes caused by an increase in the production of progesterone. This increase in progesterone levels signals that ovulation has taken place or that an embryo has successfully implanted, resulting in pregnancy.

Measuring temperature to determine ovulation activity.

body temperature in the morning before getting out of bed. Measuring and tracking daily BBT with a special thermometer can help determine when the ovary releases an egg (ovulation) and help a couple figure out the most fertile days of the month. BBT rises on the first day of ovulation. The most fertile times are the two to three days before BBT hits its highest point and the 12-24 hours after ovulation.

This is the temperature that is measured each day of the menstrual cycle at the same time (usually upon awakening).

Your body temperature when taken at its lowest point, usually in the morning before getting out of bed. Charting BBT is used to predict ovulation. BBTs are not very reliable while taking fertility medications. Biphasic: A BBT pattern consistent with ovulation and the formation of the corpus luteum, which secretes progesterone. This hormone will elevate the basal body temperature about one-half degree during the latter half of the menstrual cycle. Monophasic: An anovulatory BBT pattern where the temperature remains relatively constant throughout the cycle. Triphasic: Similar to a biphasic BBT pattern, but adds a jump to a third level of temperatures around the time implantation should occur and may indicate pregnancy.

The body temperature of a person immediately upon awakening, before any activity. When the temperature is recorded daily on a graph, a jump in temperature (about 0.5°F) may indicate ovulation. A drop in temperature may be evidence of the onset of menses or a miscarriage. The temperature can be taken orally or rectally.

Temperature taken each morning at the same time. During the second part of the cycle (after ovulation), the basal body temperature is slightly higher than during the first part of the cycle.

Basal body temperature is the body temperature measured immediately after awakening and before any physical activity has been undertaken. In women, ovulation causes an increase of one-half to one degree Fahrenheit (one-quarter to one-half degree Celsius) in basal body temperature (BBT); monitoring of BBTs is one way of estimating the day of ovulation. The tendency of a woman to have lower temperatures before ovulation, and higher temperatures afterwards, is known as a biphasic pattern.
