What is basal body temperature?

Basal body temperature is the lowest possible temperature of a human body when it is totally at rest.

Normal basal body temperature

Normal value of a person’s basal body temperature is between 97 and 97.5 degree Celsius. Basal body temperature is achieved just before the ovulation and stays for around 24 hours. After 24 hours, the body temperature starts to rise up again.

Just after the ovulation and after about 24 to 48 hours progesterone comes over and its higher levels increase the basal body temperature. This stays for almost 72 hours. If the fertilization does not occur, the body temperature lowers and indicates the start of menstruation phase of menstrual cycle of a fertile woman.

Implementation of knowledge of basal body temperature

Knowing the physiology of basal body temperature, one can understand its clinical implementations in a woman’s life. We can enlist them in the following lines.

  • As a birth control method

If a couple is trying to avoid the pregnancy, they can use the knowledge of basal body temperature for contraception. A female keeps record of her basal body temperature every morning and when it is 97. She knows it is the time for ovulation. Avoiding an unprotected intercourse during ovulation for about 48 to 72 hours means you are safe now and won’t get pregnant.

  • For conception

Same information can be used for a couple which is trying to conceive, and all other laboratory tests are normal otherwise. When the basal body temperature falls, now is the time to try to conceive and one must know this is the only time of the month when they can try their luck.

  • Diagnostic tool

Knowledge of the basal body temperature can also be used as a diagnostic aid for a couple of hormonal changes. Infertility is a growing issue in today’s world and the basal body temperature can be used to know the time of ovulation or if any ovulation is taking place or not.

It can also be used as the way of calculating the exact age of the fetus and expected date of delivery. Last menstrual period date only can give you an estimate with an error of two weeks. But this method is more accurate.
