'infertility' originates from Latin, specifically the word 'infertilitas,' where 'in-' meant 'not' and 'fertilis' meant 'fruitful.'

'infertilitas' transformed into the Old French word 'infertilité,' and eventually became the modern English word 'infertility.'

Initially, it meant 'not fruitful or productive,' but over time it evolved into its current meaning of 'inability to conceive children.'
