Ovulation refers to a period of time in a woman's menstrual cycle, usually about 14 days before her next period. This period is a very important part of the female reproductive cycle because it is when the woman releases her eggs, allowing fertilization to occur.

1. Increase in body temperature: During ovulation, a woman’s body temperature will increase by 0.5 to 1 degree Celsius. This is the result of the body increasing its metabolic rate in order to release the egg.

2. Increased appetite: During ovulation, a woman’s appetite may increase because her body needs to provide enough nutrients to release the egg.

3. Increased sexual desire: During ovulation, a woman’s sexual desire may increase because the body needs to provide sufficient energy for fertilization.

4. Increased vaginal secretions: During ovulation, a woman’s vaginal secretions may increase, making it easier for sperm to enter the body.

5. Transparent eggs: During ovulation, a woman’s eggs may become transparent, which is also one of the important characteristics of fertilization.

Ovulation is very important for women's reproductive health. If ovulation can be accurately predicted and fertilization occurs during this period, women can avoid expired eggs or failed fertilization. Therefore, understanding the characteristics of ovulation and taking corresponding measures can help women better prepare for a healthy married life.
