What should I do if women's underwear has a yellow pungent smell?

The yellow secretion on women's underwear is leucorrhea. The main components of leucorrhea are leucorrhea and cervical secretion, which is a normal physiological phenomenon after puberty. But the normal leucorrhea state should be egg white-like, and there should be no obvious odor. If leucorrhea touches underwear, it is normal that the secretion will turn yellow to a certain extent because of the oxidation of air. If the leucorrhea is yellow, we should consider whether there is the possibility of vaginal inflammation. You can check vaginal secretions to find out whether there are bacteria, mold or trichomonas infections in the secretions, and then use drugs to treat them according to the inspection results. Paying attention to personal hygiene at ordinary times, taking a bath frequently and changing underwear frequently will help to improve.
