Which are the only two women-only sports at the Summer Olympics?

The only two sports that are women-only are rhythmic gymnastics and artistic swimming. Rhythmic gymnastics uses props to add to the grace and beauty of the movements. Artistic swimming, which used to be synchronized swimming, is incredibly impressive synchronized movements in the water including synchronizing with the legs out of water and the upper body below.
