Pre Seed Lube?

Wendy

So my husband and I have been trying to have a baby for the past year and a few months. We had a miscarriage last month. It's been so hard but we are trying to stay positive. A colleague at work told me I should try the Pre Seed lube because it would help his sperm swim better. She said her friend had trouble too and once she used that one simple thing they had a baby. Any one use it and have some stories to share? Does it help? Does it not?
