Polyandry is a form of polygamy in which a woman takes two or more husbands at the same time. Polyandry is contrasted with polygyny, involving one male and two or more females. If a marriage involves a plural number of "husbands and wives" participants of each gender, then it can be called polygamy, group or conjoint marriage. In its broadest use, polyandry refers to sexual relations with multiple males within or without marriage.

Polygamy is the practice of marrying multiple spouses. When a man is married to more than one wife at the same time, it is called polygyny. When a woman is married to more than one husband at the same time, it is called polyandry. In sociobiology and zoology, researchers use polygamy in a broad sense to mean any form of multiple mating.
