I got pg while using it, but mc. I do know several women on the pg forum that got pg using it, too. One had been trying for many yrs and got pg the 1st time she used it. She nicknamed the baby "Preseed Jr", lol
I have used Pre-Seed but not with any luck. I have some underlying fertility probs so I can't say for certain whether the stuff works or not. I do know that it works good as a lubricant and feels pretty natural.
