Root Explanation
Antifertility is formed from "anti-" (meaning against) and "fertility" (from Latin "fertilitas", meaning the quality of being fertile). The word describes a condition or substance that works against fertility.
Memory Tip
Think of 'against' ('anti-') fertility ('fertility') — that's why antifertility means something that opposes the ability to conceive.
