Does the most common vaginal infection relate to infertility, or can it put an existing pregnancy at risk? Here's what you need to know.

When you find out you’re pregnant, everything supposedly changes. And you make a lot of changes—in your diet and lifestyle. And yet many seemingly insignificant habits remain and these can have a big impact on a healthy pregnancy and a healthy child.
Your exposure to BPA is probably not one of the things you set about changing. But you might want to rethink that. It’s a frequent component of a wide variety of common consumer products and plastics. Unfortunately, BPA is quite adept at leaching out of things that contain it and into food, water, and our bodies. According to the Centers for Disease Control, 93 percent of all Americans have bisphenol-A in their bloodstreams.
This is of concern for expectant moms and moms of young children because BPA is believed to mimic hormones and disrupt the endocrine system that’s responsible for assuring proper fetal development. These mechanics are incredibly sensitive—hormones released in amounts as tiny as a tenth of a trillionth of a gram control the womb environment and fetal growth. No doubt that’s why countless studies have associated exposure to BPA with a greater risk of reproductive and developmental disorders, and why the FDA has expressed concern about its possible effects on the brain, behavior, and prostate glands in fetuses and infants.
The good news is that BPA can’t touch us unless we touch or ingest it. Here are the chief places it hides. Knowing these can help us steer clear—now and in the future:
What To Do: Many cans are lined with a protective resin that contains BPA, which easily migrates into whatever those cans contain. Substitute frozen, dried, and/or fresh varieties of the canned foods you normally consume. Or look for them in glass containers. Especially avoid acidic items like canned tomato products, fruits, and soda, which leach more BPA than low-acid foods.
Watch Out For: Cans labeled “BPA-free.” Though nontoxic linings do exist, many BPA-free products simply use a substitute called bisphenol-S that appears to behave in much the same way. Check with the manufacturer.
