Funny to see this thread. I'm actually on a Uro/Gyn rotation as we speak. In fact, I just walked out of the OR where they were doing a pubovaginal sling, A/P vaginal repair, and a TVH.
Anyway, from what I can see, the lifestyle isn't too bad. Our attending is in the OR 1-2X week, with the remainder of her time in clinic.
From what I've heard, there isn't an overwhelming amount of interest in the GYN subspecialties, making it relatively easy to land a fellowship. If I get any one-on-one time with the attending, I'll ask her about this and post what she says.
