However, the Ghanaian government has been working to promote monogamy and discourage polygyny. In 1985, the Marriage of Customary Unions Law was enacted, which requires men to obtain the consent of their first wife before marrying another woman. In addition, the 1992 Constitution of Ghana guarantees women's rights and equality, and discourages the practice of customary laws that are discriminatory against women.
As a result of these legal reforms, the practice of polygyny has declined in Ghana in recent years. However, it still exists in some rural areas and among certain ethnic groups. According to a 2010 Demographic and Health Survey, about 7% of married women in Ghana were in polygamous unions.
The debate over polygyny in Ghana is ongoing, with some people arguing that it is a cultural practice that should be respected, while others argue that it is discriminatory against women and should be eliminated.
