A 1995 study performed by the American Psychological Association in response to the book The Bell Curve (which investigated intelligence differences between different social classes) shows no difference in average IQ between sexes.
A 1999 controversial study by Richard Lynn in which he analyzed data from a number of published tests (such as the standardized g-loaded Wechsler Adult Intelligence Scale-Revised) found that the mean IQ of men exceeded that of women by approximately 3-4 IQ points. Lynn's meta-analysis, conducted in 2004, examining sex differences on the Standard and Advanced Progressive Matrices (comprising various g-loaded tests of non-verbal reasoning) also found that men exceeded women by an average of 5.0 IQ points.
Males aged 17 - 18 years were found to have an average of 3.63 IQ points in excess of their female equivalents in a 2005 study from the University of Western Ontario. These differences in G (factor) were found through the whole distribution of scores, at all socioeconomic levels and noted in several ethnic groups.
Other recent studies have concluded IQ performances of men and women differ little. Analyzing data from 2,404 individuals "California Verbal Learning Test " concluded that "When mediating variables were controlled, gender differences tended to disappear on tests for which there was a male advantage and to magnify on tests for which there was a female advantage." In his book, Developmental Influences on Adult Intelligence: The Seattle Longitudinal Study, K. Warner Schaie concludes that there are few gender differences in spacial competencies.
I like the statement from Donald Trump's blog site(http://www.trumpuniversity.com/blog/post/2008/02/are-men-smarter-than-women.cfm) that states "An analysis of 30 different studies shows that men and women are fairly equal in terms of overall IQ, but women tend to underplay their own intelligence while men overestimate theirs."
In my personal opinion, I believe men and women are equal in terms of ability to develop intelligence. It is one's choice and willingness to acquire wisdom and knowledge that will determine the level of intelligence.
Be Blessed.
