The term superfecundation is derived from fecund, meaning the ability to produce offspring. Heteropaternal superfecundation refers to the fertilization of two separate ova by two different fathers. Homopaternal superfecundation refers to the fertilization of two separate ova from the same father, leading to fraternal twins. While heteropaternal superfecundation is referred to as a form of atypical twinning, genetically, the twins are half siblings. Superfecundation, while rare, can occur through either separate occurrences of sexual intercourse or through artificial insemination.

They are classified according to the trigger that opens the channel for such ions, i.e. either a voltage-change (``Voltage-gated'', ``voltage-sensitive'', or ``voltage-dependent'' sodium channel also called ``VGSCs'' or ``Nav channel'') or a binding of a substance (a ligand) to the channel (ligand-gated sodium channels).
