‘Superfecundation’; famous’ choice for word of the.. month

Superfecundation

Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse. The term is also sometimes used to refer to the instances of two different males fathering fraternal twins, though this is more accurately known as heteropaternal superfecundation. This therefore leads to the possibility of twins also being half-siblings. The term superfecundation is derived from fecund, meaning the ability to produce offspring.
