Etymology: "Oestradiols" is simply the plural of "oestradiol," the name for a steroid hormone that belongs to the estrogen family. The plural form is used when chemists or physiologists refer to more than one such compound, such as the naturally occurring isomers or the various forms found in different species and tissues. The singular "oestradiol" is built from "oestr-", the combining form tied to "oestrogen" and the word's older root in "oestrus" (the period of fertility in many female mammals), plus the chemical suffix "-diol," which signals a molecule carrying two hydroxyl groups. The name thus encodes both its biological role and its chemical structure, a pattern typical of modern steroid nomenclature.
