Leucorrhea is a kind of liquid in women's body, usually transparent, consisting of secretions from the vaginal mucosa and lochia during uterine contractions. However, many people believe that large amounts of leucorrhea only occur during ovulation. Is this correct? Let’s explore it.

Therefore, we can conclude that the zona pellucida appears throughout a woman’s menstrual cycle and is usually most abundant during ovulation. However, this does not mean that zona pellucida is not present or less numerous at other times. In fact, the appearance and number of the zona pellucida may also be affected by other physiological factors, such as vaginal inflammation, uterine disease, frequency of sexual intercourse, etc.

Therefore, we should not only pay attention to the appearance of the zona pellucida during ovulation, but should pay attention to women's physical health, regular physical examinations, and timely detection and treatment of diseases to ensure their reproductive health. At the same time, we should also pay attention to keeping the vagina clean and hygienic to avoid infection with bacteria and viruses, thereby protecting our own health.
