I found this comment on a site discussing that very thing. It's something that's just not normally talked about or it's just ignored or put up with but there is definitely a valid debate here.

"It is really surprising that there is still public controversy about the question of male doctor eroticism during a pelvic exam. The medical community recognizes the problem - Why don't you ladies? I will summarize what I see on the matter, and you tell me what facts I have wrong and were my logic has gone astray. Medical textbooks inform the young male medical student that it is "inevitable and unavoidable" that erotic sensations will occur while doing a pelvic exam. Textbooks at least into the 1980's provide this caution. Medical students relate stories that male professors would often comment that "if you do the pelvic correctly you won't need extra lube when you do the bimanual exam." Occasionally medical journals publish cautionary memoirs about young male doctors who "fall in love" with female patients while looking at and feeling the patient's breast and genitals, the tale always ending with a warning from an older colleague. The medical profession has frequently ordered surveys by medical school personnel to determine the extent of sexual violations during intimate encouters in the doctor's office. The published results of self-confession indicate high rates of abuse by male gynecologist (not ear, nose and throat doctors), sometimes running as high as 20%. When male gynecology developed over one hundred years ago there was no denial of eroticism for the male. The novel practice of a man examining the female anatomy was simply defended as a practical necessity - there was no female in the profession to do the job. You want good health, you go to the male doctor. As I have said, textbooks and procedures acknowledged the explosive nature of the exam and doctors quickly set up the chaperone sytsem to reduce the tension. It is only recently as female doctors have moved into the field that male doctors and their followers have come up with the absurd notion that a male can examine a female body in the most intimate manner, and experience absolutely no sexual response. In other words, it has been discovered that male gynecologists are unique in the human species - after six million years of evolutionary development in which the male "automatically" responds to the sight and touch of the female genitals, this all can be blocked out by a couple years in the medical lab. To those of you who comment that the pelvic exam is a simple medical procedure, I say of course it is, but what is the real nature of that procedure. To those of you who say you feel comfortable with your male doctor, I say your comment tells us nothing about what the male doctor is thinking nor anything about your level of awareness. To those of you who say all I want is the best doctor, I respond that all of us want that and I want more. I receive what I want from my female gynecologist. Common sense and a bit a research will indicate to all that it doesn't matter whether he is wearing a white coat and a stethescope, or a tweed jacket with a pipe, he is still underneath a man."
