Vaginal lubrication is natural and varies
Vaginal lubrication is naturally produced. The cells in the vagina produce healthy bacteria that keep the vaginal area moist. Some degree of vaginal lubrication is normally present even without sexual arousal. Engorgement of blood vessels from increased blood flow during sexual arousal produces lubrication needed to facilitate comfortable sex. The Bartholin glands that are present in the vaginal area secrete fluid that enhances vaginal lubrication. The amount and consistency can change with hormonal cycles in women.
Conditions that affect vaginal lubrication
Most vaginal lubrication comes from seepage through the blood vessels that supply the walls of the vagina. Normal lubrication is clear, odorless and non-irritating. Menopause, breast feeding, cancer treatment, smoking, immune dysfunction, medications and ovarian surgery result in decreased estrogen levels. Estrogen decline causes the vaginal walls to thin and become less elastic, leading to vaginal dryness.
Why vaginal lubrication varies
A variety of organisms contribute to vaginal health and lubrication. The most prevalent is lactobacili, found in probiotics. Normally, the PH of the vagina is slightly acidic because of beneficial bacteria. The vagina and cervix, which is the opening to and lower part of the uterus, produce lubricating mucous. The consistency and amount of lubrication change with menstrual cycle and after menopause. Estrogen decline contributes to loss of vaginal lubrication. Two weeks after menstruation lubrication normally increases, producing a noticeable discharge. Vaginal lubrication varies throughout life, and is affected by many factors. Infection, medications, menopause, breastfeeding, emotions, sexual arousal and alcohol can all affect the amount of vaginal lubrication experienced by women.
