Why do men become gynocologists?

It's a job. People usually follow a career path because they have passion for it and as a result excell in their job.
Why not? As a specialist, i get to help women of all ages, be involved in childbirth, and still get to perform life-improving, life-saving surgeries. I get to provide primary & preventive care, follow patients through different phases of their lives, and perform procedures. Very few specialties provide all of these components. Not only do I enjoy my work, i'd like to think that i'm quite good at it.
