Your own natural vaginal secretions hinder the sperm’s efforts to enter the cervix. Lubricants slow sperm down even further. This increases the likelihood that the sperm will die before they reach the egg. Studies have shown that lubricants harm sperm and inhibit efforts to conceive.
If you need lubricant for comfort during intercourse, do not despair. Many couples rely on a home remedy in lieu of store-bought lubricant. Some couples use egg whites as lubricant while other couples use water.
There are products on the market designed to aid in lubrication but not impede fertility efforts, but your best bet, if possible, is to go without. Try spending more time in warm-up so that lubricant is not really missed during intercourse.
When you are trying to conceive, you want to tip the scales in your favour as much as possible. Avoiding the use of lubricants will only aid in your quest to conceive.
