The race issue doesn't light my fire as much as the gender issue does.
I would only consider a female gyn now that they are available.
There are always individual differences but there is no changing nature.
Men for all times have liked to break things, fix things, build things and tinker and be aggressive.
Women like to nurture, build relationships, do community activities, mess with kids, Why wouldn't it affect the types of specialties in medicine they choose..
The gender of a person could play a role, but that may be more cultural and what a woman is doing these days. There are women who are not wives and mothers who would make VERY good surgeons.
