How long does the temperature rise last after ovulation?

Women all know that during the normal ovulation period, women's body temperature will change to a certain extent. Some women will have a low body temperature, while others will have a high body temperature. This is often caused by different physical constitutions or different levels of physical health. Therefore, when women's body temperature rises after ovulation, they need to find the reason. So how long will the temperature rise after ovulation last?

First, how long will the temperature rise last after ovulation? The menstrual cycle is regular, with each cycle lasting 28-30 days. Ovulation usually occurs about 14 days before the next menstruation. The 10 days between 5 days before ovulation and 4 days after ovulation are the ovulation period, which is also the fertile period. During the menstrual cycle, the basal body temperature before ovulation is often lower. Normally, the body temperature before getting up in the morning (i.e., basal body temperature) is below 37 degrees, approximately 36.4-36.6 degrees. The body temperature drops slightly during ovulation, and rises by an average of about 0.5 degrees after ovulation, and remains at this level until the onset of menstruation, when it begins to drop.

Second, the method of measuring basal body temperature is: after waking up every morning, do not get up, preferably in the same time period, measure your body temperature with an oral temperature meter. Generally speaking, the body temperature is always around 36.5 before ovulation. The body temperature drops slightly during ovulation. After ovulation, the temperature rises to around 37 degrees, with an average increase of about 0.5 degrees, and continues until the next menstruation, and then returns to the original body temperature level. If you measure your basal body temperature for three consecutive menstrual cycles, you can estimate the ovulation date more accurately. In addition, measure your body temperature every day and record it on a paper form to observe changes in body temperature at any time.

What changes will occur in body temperature during ovulation? During ovulation, body temperature changes into two phases, high and low. Body temperature will rise during ovulation. When the human body is in a state of complete rest, free from mental and all objective interference, the measured body temperature is called basal body temperature. The most accurate temperature is measured when you wake up at 6-7 in the morning but have not yet gotten up to move around. Basal body temperature can more accurately reflect the ovulatory function of the ovaries and the corresponding endocrine levels. The follicular phase is before ovulation, during which the ovaries secrete estrogen and the basal body temperature is mostly passively kept below 36.6°C. After ovulation, a corpus luteum is formed in the ovary, which secretes progesterone. Progesterone has a thermogenic effect on the central nervous system, raising the basal body temperature by 0.3-0.5°C. The increase in body temperature continues until 1-2 days before the onset of menstruation and then begins to decline. In this way, the changes in basal body temperature during an ovulatory menstrual cycle present a biphasic curve. When the temperature transitions from low temperature to high temperature, an extremely low temperature will occur. The day when the extremely low temperature occurs is the ovulation day.
