Usually, leukorrhea occurs throughout a woman’s menstrual cycle and becomes apparent after menstruation clears. At different times, the amount and nature of leukorrhea may vary greatly.
Before ovulation, leukorrhea is usually transparent, small in volume, odorless and not easily stretched; during ovulation, leukorrhea is abundant, thin and transparent and can be stretched up to 10 cm or more; after ovulation, leukorrhea is more turbid and gradually decreases in volume. If the patient has inflammatory stimulation, the leucorrhea usually appears abnormal, such as odor, high volume, yellowish green, or tofu-like or foamy. Therefore, women can often determine ovulation by the nature of the leukorrhea, and thus speculate on the probability of pregnancy after intercourse.
When a patient has abnormal leukorrhea, it is recommended to go to the hospital for a routine leukorrhea examination to determine if targeted treatment is needed based on the results of the leukorrhea examination.
