Why fertility-friendly lubricant matters

Not all lubricants are safe for conception

25%

Clinical research shows that around 1 in 4 couples trying to conceive experience vaginal dryness or discomfort, leading many to reach for a lubricant. But studies — including guidance from the World Health Organisation — show that many common lubricants can impair sperm function, slow sperm movement, or create a barrier that makes fertilisation more difficult.

Clinically tested for sperm safety

Tested against fertile donor sperm

In a controlled laboratory study using computer-assisted sperm analysis (CASA) — the gold standard for sperm testing — conducted at a UK NHS andrology clinic:

FertilSafe® PLUS — Best performer

Caused the smallest loss of progressive sperm movement among all commercial lubricants tested, preserving motility and swimming speed.

Standard lubricants — Underperformed

Significantly reduced sperm motility compared with FertilSafe® PLUS and sperm-safe alternatives.

Saliva — Worst performer

Caused the greatest sperm damage of everything tested in the study.
