This is too broad of a question to answer for many reasons.
First, all tests that look at gender disparities are usually flawed. There are too many variables that you cannot account for. Second, there are social issues in places that might socialize men and women in different ways. Hence, the outcome of these studies is not perfect by any stretch of the imagination. Part of the reason why Lawrence Summers, the former president of Harvard, had to step down is when he stated that men were better in sciences than woman.
Second, people are individuals and this is far more important than the gender. In other words, some men excel in a subject and some do not. This is the same of women. So, it is much better to look at the individual than the population as men and women. There is much more precision in examining individuals.
In light of these point, I do not believe that we can make general statements on academic aptitude when it comes to men and women.
