Ovulation refers to the time period when an egg is released from a woman's body, usually between the 14th and 17th days of the menstrual cycle. This period is very important for women's reproductive health, because eggs are the core substance in female reproductive cells. If the eggs cannot be discharged normally, it may cause fertility problems.

- Increase in body temperature: During ovulation, a woman's body temperature will rise by 0.5 to 1 degree Celsius, which may be caused by the egg waiting to be fertilized in the ovary.

- Appetite changes: During ovulation, women may feel an increase in appetite and want to eat high-protein, high-energy foods to meet the body's demand for nutrients.

To ensure their own reproductive health, women should pay close attention to their body temperature and symptoms, and engage in appropriate exercise and dietary control during ovulation to help promote egg discharge and sperm encounter. If a woman has any health problems, she should consult a doctor to ensure proper diagnosis and treatment during ovulation.
