Polycystic ovaries with egg white-like discharge is considered to be related to ovulation, vaginitis and other factors. 1. Ovulation: patients with polycystic ovary syndrome ovulate irregularly, when the patient appears to ovulate, due to the rise in the level of estrogen in the body, so it will lead to increased secretion of mucus from the vagina and cervical tissues, so there will be an egg-white-like discharge. 2. Vaginitis: Since the vagina is an environment where bacteria exist, when the body’s resistance is lowered, it will lead to the proliferation of anaerobic bacteria and other pathogenic bacteria, which will be manifested as a large amount of egg-white discharge, accompanied by vulvar itching and leukorrhoea odor. For patients with polycystic ovary syndrome, if there is egg-white discharge, combined with vulvar itching and other discomforts, it is recommended that the patient go to the gynecology department of a regular hospital, complete the examination of the leukorrhea and other related examinations, and then treat the cause of the disease positively.
