Is measuring body temperature an effective method of contraception?

Generally speaking, the temperature method of contraception has some effectiveness, but it cannot fully achieve contraceptive effects. The specific analysis is as follows:

During the menstrual cycle, a woman's body undergoes certain hormonal changes. During the follicular phase, the ovaries mainly secrete estrogen, and at this time the body temperature is relatively low and stable. As the follicles develop and mature, on the day of ovulation the egg is released, and the ovaries begin to form the corpus luteum, which secretes large amounts of progesterone. Progesterone acts on the hypothalamic thermoregulatory center, causing the basal body temperature to rise. By measuring body temperature, women can roughly determine their ovulation period. If sexual intercourse can be avoided during this period or reliable contraceptive measures are used during this time, the possibility of pregnancy can be reduced.

However, the temperature method of contraception is a natural contraceptive method and cannot achieve absolute contraceptive effectiveness. Body temperature can be affected by sleep quality, illness, emotional fluctuations, and other factors, leading to irregular temperature changes, thus affecting the accuracy of ovulation period prediction.

If women have contraceptive needs, it is recommended to combine other contraceptive methods, such as using condoms, taking oral short-acting contraceptives, etc., which can better prevent unintended pregnancies.
