Nah--it ain't genetics...It's all the endocrine-disrupting chemicals we've been exposed to over the years.
Common herbicides can turn male frogs (& many other species) into egg-laying females, so it's easy to imagine something similar going on with the human species. I'm convinced it's widespread and only a matter of time before scientists begin to realize why so many genetic men are realizing they're more feminine than their parents' generations were.
This could affect one's genetics, too, I suppose, but I'm no scientist.
