Ah yes... another volatile subject... muwahaha... Well, my personal opinion is that intelligence has too many aspects to be measured by one test. Some of you may be familiar with the 8 intelligences theory by Howard Gardner. Basically, it states that there are 8 measures of intelligence, including: linguistic, logical, musical, spatial, bodily kinesthetic, interpersonal, intrapersonal, and naturalistic.
IQ tests only measure logical intelligence.
Most of the above mentioned intelligences are self-explanatory, but I'll elaborate on some of the more obscure ones...
Spatial intelligence is "a mental process which is associated with the brains attempts to interpret certain types of incoming information. This information is basically anything visual - pictures, maps, plans etc. While other types of intelligence (such as mathematical ability) are historically esteemed by society, Spatial ability is probably and silently the most vital aspect of the humans mental capabilities. Without the ability to comprehend and interpret visual information something as apparently straightforward as remembering how to get to the front door of our house (from the living room!) would be beyond us."

Interpersonal intelligence is understanding other people and is commonly referred to as "streetsmarts," social skills, or sometimes just common sense.
Intrapersonal intelligence is understanding yourself and being secure with yourself. Basically, it amounts to mental stability and knowing your limits.
Naturalistic intelligence is basically your ability to survive in the wild.
As far as the genders go, men would likely have more experience and more of an aptitude in the traditional logical intelligence, because it is closely connected to math. Obviously, there are plenty of women that are good at math, but men tend to find it more interesting while women avoid it.
It's not so much a matter of biology as it is culture. Men are encouraged to become the scientists and engineers while women focus more on socially oriented work. Therefore, it's not surprising that women tend to be better at interpersonal intelligence. A lot of women are just better in communicating with the masses than men are...
Ironically, men tend to be better at intrapersonal intelligence, because of the self-esteem that testosterone often conveys in men. Women are more likely to suffer from depression, and some have suggested that women are more prone to mental instability... Whether it's a matter of hormones or culture, it's kind of hard to tell.... Granted, testosterone is a double-edged sword, because the confidence it invokes often leads to risky or stupid behavior, which is an indication of shortcomings in intrapersonal intelligence (because of the "knowing your limits" factor).
Linguistic, musical, bodily kinesthetic, spatial, and naturalistic intelligences seem to depend more on the individual than on gender.
