As an OB/GYN in practice for a little less than a decade with a busy OB and surgical practice, let me address some of the above comments:
1. "Sloppy surgeons" - I can see where your exposure to certain practitioners might color your view. It is a view held within our specialty as well. However, for what it is worth, I have seen my fair share of poor general surgeons as well. I personally believe that an extra year of residency would benefit the surgical side. I was fortunate in that I trained in a large, academic surgery focused residency and I had exposure and training in technical minimally invasive and vaginal procedures that smaller programs cannot provide. There is a very significant cadre of gynecological surgeons who take great pride in our surgical skills and acumen.
2. Clerkship - I agree - it can be pretty malignant. Again, it depends on who you get. As a more senior resident, I personally enjoyed teaching, but you need to realize it is the attendings' job (or maybe the chief residents') to teach. The residents are there to learn as well. As a resident, I found a certain cadre of medical students, how should I say this, intolerable. The ones who wanted to know where the call room was, bitched about not getting deliveries when they refused to get up, and disappeared when help was needed for exposure in a complicated vaginal repair at 3 in the morning. I agree that it is a bit shitty to be paying for the privilege to be up all night doing scut work, but that is the life of OB/GYN house staff. I recommend, however much you may detest the idea of being an OB/GYN, come to the clerkship with an open mind and be willing to pitch in. Knowing the cardinal movements of labor, the layers of the anterior abdominal wall, and the basics of pelvic anatomy will go a LONG way to making your clerkship more enjoyable.
