Types of Multiple Births: Terminology

Monozygotic – multiple (typically two) foetuses produced by the splitting of a single zygote

Dizygotic – multiple (typically two) foetuses produced by two zygotes

Polyzygotic – multiple foetuses produced by two or more zygotes

Litter – the offspring produced by a multiple birth in non-human placentals

Terms used for the order of multiple births are largely derived from the Latin names for numbers.

Two offspring – twins

Three offspring – triplets

Four offspring – quadruplets

Five offspring – quintuplets

Six offspring – sextuplets

Seven offspring – septuplets

Eight offspring – octuplets

Nine offspring – nonuplets

Ten offspring – decaplets

Eleven offspring – undecaplets

Twelve offspring – duodecaplets

Thirteen offspring – tredecaplets

Fourteen offspring – quattuordecaplets

Fifteen offspring – quindecaplets

For five, quintiplets (spelling?)

For four…quartuplets? ( don’t know for that one…)

Quadruplets.
