'fertility-supporting' originates from the combination of 'fertility' and 'supporting', where 'fertility' refers to the ability to reproduce and 'supporting' means to aid or assist.

'fertility' comes from the Latin word 'fertilitas', and 'supporting' comes from the Old French 'supporter', which means to bear or hold up.

Initially, 'fertility' meant the ability to produce offspring, and 'supporting' meant to hold up or assist. Together, they evolved to mean aiding in the ability to reproduce.
