From the Research
Pre-Seed lubricant is the most suitable option for couples trying to conceive, as it has the least negative effect on sperm motility and vitality, according to the most recent and highest quality study 1. When considering the use of lubricants during conception, it's essential to choose a product that is "sperm-friendly" to minimize any potential negative effects on fertility.
- Pre-Seed lubricant is specifically formulated to mimic the natural pH and osmolality of cervical fluid, making it an ideal choice for couples trying to conceive.
- Regular lubricants, such as KY jelly and Durex, can contain ingredients that can damage sperm or create hostile environments, altering pH levels or creating physical barriers 1.
- The study published in 2025 1 compared the effects of five coital lubricants on sperm motility and vitality, and found that Pre-seed demonstrated sperm parameters comparable to the vaginal fluid simulant control at any incubation time.
- In contrast, KY jelly, Vaseline, and Baby oil reduced progressive sperm motility at certain times, while Durex showed a significant decrease in sperm motility and deteriorated sperm vitality at 60 minutes 1.
- Another study published in 2014 2 also found that Pre-seed had the least negative effect on sperm function, with Conceive Plus being a close second.
- It's crucial to note that while Pre-Seed lubricant can support fertility, it does not enhance it, and addressing underlying fertility issues through medical evaluation is more important than lubricant choice if conception has not occurred after 12 months (or 6 months if over 35) 2, 3, 1.
- For couples experiencing vaginal dryness during their fertile window, Pre-Seed offers a solution that allows for comfortable intercourse without compromising sperm function, and it should be applied internally using the provided applicators about 15 minutes before intercourse, following package instructions for the recommended amount (typically 2-3 grams).
