Pre-Seed is the only lubricant formulated by a woman Sperm Physiologist.
Meet Dr. E and learn more about her research.
I loved Pre-Seed! We used it to conceive our daughter Kattie… We love the texture and the fact that it didn't cause any vaginal dryness which happens with the other lubricants we used…
Our patients love your products! Your products are the only lubricants we recommend. Thanks for making such great products!
I am so glad I can confidently recommend a lubricant to my subfertile patients that won't work against them.
Safe for use by couples trying to conceive—Pre-Seed is the first lubricant ever allowed to make this statement. The safety of Pre-Seed for sperm is supported by independent, published studies.
Woman Sperm Physiologist Dr. Joanna Ellington (Dr. E) invented this 'fertility-friendly' isotonic formula specifically to meet the need for safe lubrication when trying to get pregnant.
Pre-Seed comes with applicators to deposit the unique lubricant inside, where it can coat the vagina and external cervix and best mimic your own natural fluids in an optimal environment for sperm.
When you are trying to conceive, know the facts about vaginal lubricants. A number of medical studies report that leading “nonspermicidal” lubricants damage sperm and should be avoided if you are ready for a baby.

Having to have intercourse during the woman’s fertile time can lead to stress and increased vaginal dryness.
Women who are trying to conceive are also aware of the quality of their fertile fluids. Normally, during ovulation, these special fluids are made by the woman’s body to support sperm on their journey through the cervix to meet the egg. Fluid volumes increase, and they become more slippery (like egg whites), with a rise in fluid pH to protect sperm. As women age, or if they have hormone imbalances, these normal fertile fluid changes don’t occur, making it difficult for the sperm to swim through the cervix.
When you are trying to conceive, know the facts about vaginal lubricants. Published medical studies report that leading “nonspermicidal” lubricants can damage the ability of sperm to swim, at the same rate as a contraceptive gel! These studies recommend that “every day” lubricants be avoided if you want to become pregnant.
Even though a risk of lubricants to fertility has been known for decades, some people are still confused about their use when trying to conceive. In fact, some doctors may inadvertently recommend lubricants that can stop sperm from swimming. Just because a lubricant does not contain a spermicide or it is water soluble, does not mean it won’t harm sperm.
Common lubricants damage sperm because they have the wrong pH and are not “isotonic,” meaning they have high salt or ion levels that dehydrate sperm and stop them from swimming. Some also contain sperm-toxic ingredients, such as glycerol (glycerin). Even saliva and water can kill sperm and should be avoided when you are trying to conceive.
→Choosing the right lubricant is important to give you the best chance of getting pregnant, according to the American Society of Reproductive Medicine.
Pre-Seed was developed specifically to match a woman’s fertile fluids and to provide safe lubrication for use when trying to conceive a baby!
Published studies also show that Pre-Seed's isotonic formula is less irritating to the sensitive tissues of intimacy than other leading lubricants. Pre-Seed is safe enough to make a baby, but it also provides natural feeling mild lubrication for anyone at any time. Pre-Seed is made in America and has been trusted by TTC couples since 2002.
