To chime in again: PC statements about "equality" aside, relative to men, more women want more flexibility to raise children. This really means wanting less time requirements for work demands. There are a lot of reasons to be passionate about ENT, and among surgeons, we have it pretty good, but ENT still has higher demands relative to non procedural or shift work fields.
My wife is a hospitalist, and I can tell you that works better for her, for me, and for our family, with her working predictable shifts. (Week on/week off.) She has amazing dedication, and spends extra hours with meetings, teaching residents, etc. But the predictability of the shifts is huge for scheduling a nanny.
ENT in most facets involves some unpredictable availability. Although not particularly common (and certainly better than gen surg), you do have call demands where you sit around the hospital waiting for an add on case, or run in at night for epistaxis. In my first years of private practice, I took very little vacation, because I want to be available. (Availability is the most important "A"). In private practice, I also spend some late nights or early mornings with business-oriented meetings. Essentially, I could need someone available (either wife or nanny) to help with child care at any time, day or night. If my rhinoplasty patient has their incision dehisce, I am not going to have a colleague who doesn't do rhinoplasty cover that, because I am not on call. And for other specific niches, such as I mentioned previously, you are going to have more or less unpredictability in your patients' needs. Cancer, airways, trauma, etc. To put it another way: If both my wife and I were ENTs, it would be a lot harder.
Family-work balance issues are obviously not unique to ENT, or women-only problems, but things that come along with highly driven career individuals in any field, not necessarily medicine. Similar problems for a CEO, for example. These are things you probably consider when applying for medical school. ENTs tend to be quite driven so you tend to have high expectations for both work and family.
And of course, it depends on what your spouse does, as far as how your two careers mesh together. (Stay at home husband =no problem.)
