Vaginal dryness and low secretion during sex can occur in post-menopausal women if the decline in ovarian function and estrogen levels reduce cervical secretions and vaginal secretions. If cervical lesions and breast lesions are excluded, estriol ointment can be applied intravaginally to effectively relieve the symptoms of sexual dryness. In the case of women of childbearing age, this may be due to previous surgery on the cervix, which may reduce the secretion by damaging the glands of the cervix. It is recommended that this can be improved by using adult lubricants during sex. In addition, if vaginal inflammation is the cause, it is recommended to check the white belt routine and give the appropriate medication according to the result of the test to improve this vaginal dryness.
