From what I understand, bones can grow to meet the needs of the body. If you do lots of running, for example, your leg bones and pelvic girdle will strengthen itself along with your muscles. Your bones can also enlarge, so you could hypothetically gain a feminine figure, its just a question of how to get your bones and muscles to do the right things.
In most cases, the generation of completely new organs is impossible. It is beyond the function of the developed human body to do so. However, certain animals can change their sex (strange but true) so it MAY be possible to do this, but since I've never heard of any humans gaining sexual organs they weren't supposed to have, so I have to say as of yet I have no idea of whether or not it is possible in a human.
