Bidirectional body temperature during ovulation refers to the two body temperature peaks in which a woman's body temperature fluctuates before and after ovulation. This change in body temperature is very important for women's reproductive health, because women's hormone levels change during ovulation, which affects the development of the embryo and the health of the baby after birth.

So, what are ovulation hormone levels? During ovulation, a woman’s body secretes a hormone called HCG (human choriocarcinoma hormone), which is very important for women’s reproductive health. HCG is formed in a woman's ovaries and then transported throughout the body through the bloodstream, eventually reaching the embryo. During ovulation, HCG levels will rise suddenly and then gradually fall, a process called "fertilization."

So, how to observe a woman’s ovulation period? Generally speaking, women can determine their ovulation period by measuring their basal body temperature and observing changes in body temperature. Basal body temperature refers to the body temperature measured when a woman wakes up in the morning. It is usually 0.3 to 0.5 degrees Celsius higher than the day before. Observing body temperature changes is to record a woman's body temperature changes to determine her ovulation period.

During ovulation, a woman's body temperature will rise suddenly and then gradually drop. This change in body temperature is very important for women's reproductive health because it can help women predict the development of embryos and detect abnormalities in embryonic development in time. Therefore, women should pay close attention to changes in their body temperature and make relevant preparations when planning pregnancy.
