It is not normal for a woman to have no vaginal discharge. In normal fertile women, the vestibular gland and the cervical glands secrete a small amount of fluid every day to ensure vaginal lubrication, and the function of the glands is proportional to the level of sex hormones. If there is no vaginal secretion, it indicates low female hormone level, which will cause vaginal dryness, atrophy, painful intercourse, prone to vaginitis, and seriously affect the quality of life, which may be accompanied by menstrual disorders or infertility, which only occurs in older women after menopause, and the hormone level should be checked to determine the degree of decline. If supplementation is needed, you can choose to take oral estradiol valerate, Imazine, etc. You can also use combined estrogen ointment and progesterone ointment for application to promote the secretion of vaginal lubricating fluid from the glands and relieve the symptoms of vaginal dryness.
