Boost Your Conception Chances with Pre-Seed Lubricant

Planned intercourse, when trying for a baby, can be stressful and intimidating. The pressure of needing to perform “on demand” can lead to vaginal dryness, which many couples experience when trying to conceive. That’s where Pre-Seed Fertility Lubricant comes in.

Many couples instinctively reach for a regular lubricant to help — but this is where the trouble begins. Most lubricants sold in high-street shops are fine for everyday use, but when you are on a mission to conceive, they can actively work against you. Research shows that many standard lubes impair sperm motility and lower sperm counts, both of which reduce the chances of getting pregnant. Only motile sperm can fertilise a female egg; immotile sperm cannot make the journey.

Everyday lubricants also tend to have the wrong pH balance and incorrect salt and ion levels. These factors can dehydrate sperm or even stop them swimming altogether — precisely the opposite of what you need when trying to conceive. According to NHS guidance on fertility, sperm health is one of the most important factors in achieving pregnancy, making it essential to avoid anything that could compromise it.

Why Regular Lubricants Can Harm Your Chances

The issue with most standard lubricants is not that they are poorly made — it is that they are not designed with conception in mind. The vaginal environment during the fertile window is carefully balanced to support sperm survival. A woman’s own cervical mucus is isotonic, meaning it matches the natural osmotic pressure of sperm, allowing them to swim freely towards the egg.

Regular lubricants disrupt this balance. Many contain glycerin, which draws water out of sperm cells through osmosis, causing them to shrink and become less motile. Others have a pH that is too acidic, further damaging the sperm before they have a chance to travel. If you are also using ovulation prediction kits to time intercourse accurately, it would be a shame to undermine your efforts by using the wrong lubricant at the critical moment.

What is Pre-Seed Fertility Lubricant?

Pre-Seed was developed by Dr. Joanna Ellington, a leading sperm physiologist, specifically to address the problem of sperm-hostile lubricants. Unlike standard lubes, Pre-Seed is designed to work in harmony with sperm rather than against it. Its formula mimics the natural properties of a woman’s cervical fluid during the fertile phase, creating an environment in which sperm can thrive.

The key benefits of Pre-Seed include its pH balance, which is calibrated to match the natural vaginal pH during the fertile window, and its isotonic formulation, which prevents the osmotic damage that affects sperm in regular lubricants. It is also free from glycerin, parabens, and other compounds commonly found in standard lubricants that can harm sperm. For couples who also want to understand their fertile window better, pairing Pre-Seed with knowledge of ovulation signs can help make the most of each cycle.

Using the Right Lube When Trying for a Baby

Clinical studies have shown that sperm exposed to Pre-Seed Lubricant have significantly higher motility than those exposed to regular lubricants. Because Pre-Seed mimics the body’s own cervical fluid, it has also been found to preserve the DNA integrity of sperm — an important factor in successful fertilisation and healthy embryo development.

Studies also suggest that couples using Pre-Seed during their fertile window have a 2.4 times higher chance of achieving pregnancy than those using traditional lubricants or no lubricant at all. This is a meaningful difference, particularly for couples who may already be anxious about how long conception is taking. The Human Fertilisation and Embryology Authority (HFEA) recommends that couples trying to conceive take practical steps to optimise their chances, and switching to a sperm-friendly lubricant is one of the easiest changes to make.

Pre-Seed is available in easy-to-use applicators, which allow precise application before intercourse. It is compatible with both latex and polyurethane condoms and is safe and gentle for both partners to use.

The Best Fertility Lubricant: What the Research Says

In a 2014 study published on PubMed, Pre-Seed was tested alongside nine other fertility lubricants in research examining the effects of vaginal lubrication on sperm function. Pre-Seed came out on top, with researchers finding it had the least negative effect on sperm motility and vitality of all the products tested. Conceive Plus was ranked a close second.

For couples weighing up the options, we have a detailed comparison of Pre-Seed vs Conceive Plus that looks at the differences between the two leading fertility lubricants and helps you decide which is most suited to your needs. Both are solid choices — but the research consistently places Pre-Seed ahead when sperm motility preservation is the primary concern.

How to Use Pre-Seed Effectively

For best results, Pre-Seed should be used during the fertile window — the days leading up to and including ovulation. If you are not already tracking your cycle, using ovulation tests alongside Pre-Seed is an effective combination that many couples find helpful. The applicators provided allow the lubricant to be placed internally before intercourse, mimicking the natural lubrication of the fertile phase as closely as possible.

Pre-Seed does not require refrigeration and has a long shelf life, making it convenient to keep to hand throughout your cycle. For couples who are also monitoring basal body temperature or tracking cervical mucus changes alongside ovulation tests, Pre-Seed fits naturally into a comprehensive, fertility-aware approach to conception planning.
