It's important to remember that the male partner plays a very important role in achieving pregnancy. It is critical to have a normal sperm count (and quality) in order to get pregnant naturally. There are many things that can damage sperm, but diet and lifestyle changes can be made to enhance fertility. There are also several supplements available which could be helpful. Keep in mind, any changes made will not show up for a few months, as it takes that long for new sperm to develop.
