What is a fertility friendly Lubricant System?

A fertility friendly lubricant system enables couples, trying to conceive, to use lubricants that are pH and osmolality matched to semen during ovulation and matched to typical vaginal pH after ovulation.  Semen is neutral to alkaline, so using an acidic lubricant at ovulation may damage sperm motility. The vagina is typically acidic, which maintains a healthy defence against infection, so using a neutral to alkaline lubricant all month may impact vaginal health. The typical acidic vaginal environment protects against infections such as Bacterial Vaginosis and Thrush.

What is in a fertility friendly Lubricant System?

Ovulation tests to determine the most fertile period

Fertility Friendly Lubricants
(Pre-Seed, Conceive Plus, Zestica)

A two-pack conception friendly lubricant system. Holistic view of vaginal pH management

Guaranteed pure & natural through Soil Association Organic Certification


No purity or natural guarantees, all contain synthetic chemicals and Methylparaben as a preservative

Addresses both sperm and vaginal health, with ovulation sticks to enable self management*
