When you think about it, the vagina is a pretty undemanding organ. It’s cooperated through childbirth and nights of passion; it’s soldiered on uncomplainingly throughout years of menses and the occasional “oops”—such as the patient of mine who applied Retin-A skin cream instead of Vagisil, or the friend who used Ben-Gay. Her vagina did a little complaining then, but soon returned to its cheerful self.
Because the vagina has rarely been the squeaky wheel, we’ve tended to tend to take it for granted. As we age, however, vaginal tissue thins, loses elasticity, and becomes dry, so, like other parts of our bodies, that wheel tends to squeak a little louder.
Often, vaginal troubles can be addressed—or avoided altogether—with some TLC. While few of us think about how to maintain optimal vaginal health, maybe it’s time to give that longsuffering organ some extra attention. The two major factors in maintaining a healthy, uncomplaining vagina are a good bacterial balance and moisture.
First, a science lesson: pH is a measure of how acidic or alkaline (basic) a substance is. The pH scale ranges from 0 (very acidic) to 14 (highly alkaline) with seven being neutral. A healthy vagina is slightly acidic, in the range of 4.5 to 5. This acidity is maintained by a delicate balance of organisms, notably the bacteria lactobacillus that produces lactic acid. This slightly acid environment helps to ward off infection.
When the pH level in our vagina is out of whack, unwanted bacteria and other organisms can flourish—Candida albicans, for example, which is the fungus causing yeast infections. Sometimes it doesn’t take much to upset the balance. A surgary diet, some kinds of soap, a round of antibiotics, or even one of those nights of passion can upset the flora in the vagina. Sperm, for example, is alkaline with a pH of 7 to 8, and so is blood with a pH of 7.4, which is why hygiene is especially important if you’re still menstruating.
Here are some suggestions for maintaining a good pH balance and for overall vaginal hygiene.
