Ladies often ask if they should use pre-seed or another “fertility friendly” lubricant when doing AI. I strongly advise against doing so, unless a doctor tells you otherwise. Some ladies do get pregnant when using them, but they also clearly kill sperm. Below is an experiment I did that demonstrates that, and I have had similar results when experimenting with Conceive Plus. My guess is that if you use one of these produce BEFORE inseminating, then they get diluted within your body and maybe have little effect. But mixing them directly with semen is a recipe for failure.
Original Sample
This is my original sample under the microscope immediately before I mixed it with Pre-Seed. Swimming nicely.
Sample After Pre-Seed
This is the same sample five minutes later after I mixed it with Pre-Seed. Almost all dead.
