Environmental pollutants which mimic the effects of estrogen inside our bodies are called xenoestrogens. We are confronted with these in several ways including car exhaust, pesticides, solvents (present in nail polish and remover), emulsifiers present in soap and cosmetics, plastics (think water bottles) and synthetic hormones found in birth control pills and other drugs which can be flushed into the sewers and back in our soil and water. It's quite common for women to suffer with a drop in libido and vaginal dryness post menopause. However, it is possible to boost your sex drive and alleviate problems like menopause dryness so that you can enjoy great sex once again. The reason for this really is why these adjustments to diet also change or get a new woman's vaginal environment and PH. If that environment is alkaline, it's more friendly towards the Y or boy producing sperm. If it's acidic, it is quite tough on those self same Y sperm but friendly for the X's (or those that produce girl babies.)
