Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse. The term superfecundation is derived from fecund, meaning the ability to produce offspring.
Heteropaternal superfecundation occurs when two different males father fraternal twins. When the parents of fraternal twins are involved in a paternity suit, the odds are about 1 in 40 that the children are actually half-siblings.
