What are the main biological differences between men and women?

Men are about 10 percent taller than women.  Women usually have a larger pelvis, which makes it easier for them to give birth.  Men tend to have more upper-body strength.  Their skeletal muscles are larger and more efficient at energy conversion.

At what ages of development do these differences start presenting themselves? Are they most present before or after puberty?
