'''Heteropaternal superfecundation''' is a rare occurring [[medical]] term describing the [[fertilization]] of two or more [[ovary]] by [[sperm]] from different males. According to Academic Dictionaries & Encyclopedias, "A woman who has sexual relations with two or more men at short intervals within the same ovulatory period can be impregnated by both men," thus twin newborn children with different [[father]]s.
