Q&A: Effects of Lubricants on Getting Pregnant?
Yes and yes. Even on its own, vaginal secretion is an acidic sperm killer that repels healthy sperm before it can enter the cervix. Store-bought lubricant only slows the sperm further, leaving it more likely to die within the vagina, before reaching the egg.
Need an alternative? Try Pre~Seed, a new lubricant that’s advertised as “fertility friendly,” and doesn’t seem to harm sperm. Or, try a home remedy. Some couples find water or even egg whites works as a non-toxic lubricant. There’s also the old-fashioned option — save your money, step up the foreplay and let nature do the rest.
