What is male dominance polygyny?
Polygyny (e.g. a dominant male with a harem of several females) is more adaptive when environmental resources (e.g. water, food) are patchy (clumped) and when females occur in groups. Thus, males compete for acquisition of a group of females by fighting with other males and displaying their prowess to females.
Which primates are polygyny?
The mating system in these primates is usually polygynous (i.e., each male mates with multiple females). This type of social system characterizes galagos, lorises, some lemurs, some tarsiers, and orangutans. Notably, orangutans are the only anthropoid primates with a solitary social system.

Where is polygyny most common?
sub-Saharan Africa
Polygyny is most widespread in rural, agrarian areas of sub-Saharan Africa (Boserup 1985; Jacoby 1995; Kishor and Neitzel 1996). In these settings, human labor (particularly female labor) yields high economic value, and men use polygyny as a strategy to increase their family’s productivity (Klomegah 1997).
Why is polyandry so rare?
It is a rare form of marriage that exists not only among peasant families but also among the elite families. For example, polyandry in the Himalayan mountains is related to the scarcity of land. The marriage of all brothers in a family to the same wife allows family land to remain intact and undivided.

It’s true in the context of men who want monogamy, as well as in the context of men who just want to sleep around as much as they can. Both types of sexual behaviour exist in all of us. As humans, we can be monogamous and we can be promiscuous or polygamous, or anything else.
Are males monogamous?
The human male body provides ambiguous clues to the answer but the balance of evidence indicates that we are biologically inclined towards monogamy while retaining an urge to “sleep around”.
