It is necessary to predict the safe period, and for couples who do not want children, effective contraception is the wisest option. Some people may know about predicting ovulation period based on body temperature, but its prediction is not accurate. Because ovulation can be delayed due to exposure to cold, predicting the safe period is inaccurate, and contraception is also unsafe. So how to prevent ovulation by measuring body temperature?
How to prevent pregnancy by measuring ovulation temperature
The basal body temperature measurement method can determine the ovulation date and the safe period after ovulation, but cannot pre determine the safe period before ovulation. This method is cumbersome and has strict requirements. If body temperature is not measured according to regulations, the ovulation date cannot be accurately determined. In addition, the timing of ovulation in women is influenced by factors such as external environment, climate, personal emotions, and health status, which may result in delayed or advanced ovulation, as well as the possibility of additional ovulation. Therefore, the safe period cannot be accurately calculated, so contraception during the safe period is unsafe.
How to determine ovulation period from body temperature
After ovulation, the ovary forms a corpus luteum, which secretes progesterone. Progesterone has a thermogenic effect on the central nervous system, causing an increase in basal body temperature of 0.3-0.5 ℃, which continues until 1-2 days before menstruation to begin to decrease. In this way, the changes in basal body temperature during an ovulatory menstrual cycle exhibit a biphasic curve. During the transition from low temperature to high temperature, an extremely low temperature occurs, and the day when the extremely low temperature occurs is ovulation day.
There are many ways to predict ovulation period, and accurately knowing the ovulation date for couples who want to have children is beneficial for pregnancy. So how to prevent ovulation by measuring body temperature? However, for couples who do not want children, knowing ovulation day can be an effective contraceptive measure. It is recommended to use high-quality contraceptive devices when using contraception. Using substandard products not only fails to achieve contraceptive effects, but also poses a risk to both partners.
