Okay, time to chime in. I'm a male entering OB/GYN and frankly don't really care what anyone says about males in the field. I have heard what's been said... it hasn't affected me and I don't think it should affect anyone else either. If you're a male entering OB/GYN, you've considered the gender difference whether you realize it or not. You wouldn't have the desire to do OB/GYN if patients were not comfortable with you as their provider already. If thats the case then you already know its not an issue for you, IMO. If you like the field and see yourself having a successful, enjoyable, fulfilling career in it, then do it. Everyone is their own person, and you'll do what you'll do and make the best of the situation when necessary. There is no general rule, and I wouldn't rush to assume I'd conform to it even if one existed. Patients have been very comfortable with me, and I will make sure that continues to be the case for the next however number of years I practice.
Anyway, all that being said, I think (hope) we can all agree on:
-it depends on the individual patients preference, race, religion, etc etc or whatever other reasons she has for choosing a male or female gyn
-it depends on the individual physician and the rapport he can or cannot establish with his patients in general, and with each individual patient with their concerns, etc
-it depends on the city and state, and therefore what the predominant social preferences are, whether they are relatively conservative or liberal, progressive etc.. whatever words you want to use
-and even within the same city, it depends where you are located - neighborhoods can range from conservative or orthodox religious populations to yuppie to middle class white Christian family with 2.5 children to anything else we can think of, depending on the particular city. Obviously some are more diverse than others.
-it depends on the overall personality and environment of your department or practice, and how comfortable the patient is there
basically... it depends?
