Medical review and important information
Our editorial and medical review policy explains how we research and check our health articles.
This page provides general information and does not replace personalised advice from a qualified health professional. Always read the label and follow the directions for use. Conceive Plus is a personal lubricant intended to moisturise, lubricate and supplement natural lubrication. It is not a fertility treatment, does not treat infertility and cannot guarantee pregnancy.
If the person trying to become pregnant is under 35, speak with a GP or fertility specialist after 12 months of regular unprotected sex without pregnancy. If they are 35 or older, seek advice after 6 months. Speak with a clinician sooner if periods are irregular or absent, there is a known or suspected reproductive health condition, recurrent pregnancy loss, or concerns about sperm health. Seek urgent medical care for severe pain, heavy bleeding, fainting or other sudden or concerning symptoms.
