Conjugal relationship generally refers to sexual life, and sexual life is not recommended 3 days before the gynecological examination. If you need to have a gynecological examination, it is generally not recommended to have sex 3 days before the examination, because sex may affect the vaginal environment, destroying the acidity and alkalinity of the vagina, and may cause changes in the vaginal secretions, so it may lead to changes in the results of the examination. At the same time, if there is a colposcopy, after having sex, it may lead to the possibility of false positives, so in order to check the accuracy of the results, it is recommended to avoid sex before the gynecological examination. It should also be noted that gynecological examination should be avoided during menstruation, and it is recommended to go to the hospital for examination after menstruation is completely cleared. For details, it is recommended to consult a professional doctor.
