Polyandry

Polyandry (Greek: poly—many, andras—man) is a form of polygamy whereby a woman takes two or more husbands at the same time. In zoology, polyandry is a mating system involving a female and two or more males. Most broadly, polyandry refers to sexual relations with multiple males, within or without marriage. Polyandry is contrasted with polygyny, involving one male and two or more females. Polyandry is also distinct from group marriage, involving plural participants of each sex.
