The number was calculated from the actual sex ratio in the population compared to what it would theoretically be, if equal treatment were given to the sexes during pregnancy, birth and afterwards.
Despite Asia's robust economic growth, the report found that millions of women remained shut out of the benefits of greater prosperity.
The region, and especially south Asia, ranks near the worst in the world -- often lower than sub-Saharan Africa -- on issues such as protecting women from violence, as well as access to health, education, employment and political participation.
"Today, the Asia-Pacific region is at a crossroads," the report said. "Whether gender equality is pushed aside or pursued with greater energy amid the economic downturn depends on actions taken or not taken now by governments."
The report, launched on International Women's Day, focused on the need to improve women's rights in three key areas: economic power, political participation, and legal protection.
Helen Clark, the former prime minister of New Zealand who now heads the UNDP, said both genders would benefit if progress were made in all three sectors.
"Female participation in society can improve a country's economic position, and you can't achieve your development goals unless you have females as part of the equation," she said.
"Countries who don't do that will always fail to fulfill their potential."
