The leukorrhea does not necessarily mean ovulation: 1. Most of the leukorrhea that appears in the vagina of women is due to the influence of estrogen secreted by the ovaries. The amount of leukorrhea is small when the menstruation is just clean, and the amount of leukorrhea secretion increases during ovulation, which is colorless and transparent, with a high degree of straining, while there is more leukorrhea secretion in the late ovulation period. Therefore, it is inaccurate to diagnose ovulation by leucorrhea secretion alone, which is prone to error, When a woman suffers from gynecological inflammation such as cervical inflammation, it will also lead to increased leucorrhea secretion.
