If you are looking at a large academic institution, then all HP's will make a difference. Any of the large programs will look at those candidates who have some honors and research. The past few years board scores have been very high, but the applicant transcripts aren't as strong. Even though our institution may want to recruit males, we don't invite them unless they are just as strong as the females that apply to our program. Being a male doesn't not give them any extra points at least not here, though you may find a program that does. I think you should be meet with the OBGYN Chair or someone else in the dept. and get their feedback.
