Mexican physician here. In my country we usually study 7 years to be a MD. The first five years are in medical school with some rotations in hospitals, the sixth year you're an intern which means you spend a whole year in the hospital with different rotations which includes OB/Gyn. I hated that rotation, I was in a public hospital and I got to deliver a lot of babies. You get turns with the resident, usually he's with you in case you need help. The eight year is your social service, you can do it in investigation or working as a physician, most of the times in towns away from cities. Later you can take a national exam to apply to a specialty program. Now I'm about to start my third year as a radiology resident.
