Pre-Seed is the only lubricant formulated by a woman Sperm Physiologist.
In her book Jean M. Twenge states: “If you need some extra help, you can try a lubricant called Pre-Seed that more closely resembles natural lubrication and doesn't kill sperm."
In The Big, Fun, Sexy Sex Book its authors write: “Couples who prefer to use a lubricant may want to try Pre-Seed, a lubricant designed just for those trying to conceive.”
The authors of Sexually Speaking write: “The solution is to use a lubricant that doesn't have this negative effect on sperm. Pre-Seed has been given FDA approval to make the claim that it is safe to use for couples trying to conceive.”
The authors write: “Consider using a lubricant. Water-based lubricants and silicone-based lubricants can be used with latex condoms. ... If you're trying to conceive, ask your healthcare provider for his or her opinion about Pre-Seed or other lubricants that have been designed to be more friendly to sperm."
In this supportive guide to intimacy for women with cancer, the authors list Pre-Seed “for use even while trying to conceive.”
The author writes that Pre-Seed is “…proven to be less harmful to sperm motility movement and sperm DNA” and “if you have been using any other lubrication aids, research indicates that these may adversely affect sperm movement and can damage sperm DNA.”
Here’s what the authors have to say about Pre-Seed: "Pre-Seed, (is) a clinically proven, fertility-friendly moisturizer that mimics natural body secretions to relieve vaginal dryness. It provides an optimal environment for sperm and is delivered in a fluid that is mild on a woman’s body."
The authors of Fully Fertile state: "Bottom line is that even if you feel you don’t need it, a sperm-friendly lubricant can make the life of sperm much happier. Remember most lubricants are not sperm-friendly so you need to do some research and find one that is, such as Pre-Seed."
Dr. Falcone of The Cleveland Clinic writes: "Lubricants such as K-Y Jelly and olive oil can inhibit sperm motility. However, other lubricants such as Pre-Seed…do not."
Here’s what Dr. David and his co-author say about Pre-Seed: "If you need a little extra moisture – and many couples do at ovulation or under the stress of trying to conceive – you don’t have to do without. Look for Pre-Seed lubricant, which is specially designed for couples trying to conceive. It does not contain any glycerin or propylene glycol, the mischief makers in most lubricants. Its pH is the same as fertile cervical mucus, and it contains roughly the same amount of salts… A new Cleveland Clinic study of lubricants published in the journal Fertility and Sterility found that Pre-Seed was the only commercially available vaginal lubricant that didn’t decrease sperm motility or compromise sperm DNA."
Here’s what author Debby Herenick writes: “MYTH: A lubricant is a lubricant is a lubricant. Not so. Because lubricants are not regulated in the same way that condoms are, ... That said, recent studies have found that some lubricants (such as Pre-Seed… ) may be more “fertility friendly” than others.”
Dr. Greene in his book states: "Studies of infertility patients reveal that women are about twice as likely to experience pain during “timed sex” than spontaneous sex–largely because of decreased lubrication. Less lubrication can be a side effect of some fertility medications, but it can also be related to stress or anxiety or a lack of arousal caused by the clinical nature of scheduled sex. Many women have avoided popular lubricants because they’ve been shown to interfere with normal sperm function. There is a least one product, called Pre-Seed, that won’t reduce fertility. Pre-Seed has the proper acid-to-base balance to protect sperm."
Dr. Greenfield writes: "And some lubricants used for sex can be mildly toxic to sperm, as can douching after sex. Research has shown that KY Jelly, Astroglide, Replens, olive oil, and saliva all interfere with sperm motility. If you need a lubricant...a sexual lubricant called Pre-Seed also advertises that it is nontoxic to sperm."
Here’s what Toni Weschler, in her bestselling book, writes about Pre-Seed: "Until recently, there really wasn’t a viable option to use during the one time in your life that you probably would have appreciated it most. Luckily, though, a revolutionary new vaginal moisturizer has recently been developed that is specifically designed to mimic natural body secretions and provide an optimal environment for sperm. It is called Pre-Seed, and it works by delivering a pH balanced semen-like fluid."
