I think this concept could work, depending on what you do with it. Is it one of those things where "everyone" just does it, or are they forced to by the government or something? If it's the latter, you could have a very interesting concept for a dystopia and could explore the entire concept of gender and to what extent one's gender impacts a person's personality and fundamental identity. If it's not forced, there will be people who opt out, either for religious/moral reasons, or because they can't afford the hormones and surgery (or both, and keep in mind that this would include everyone who said the amount of genetic engineering involved gave them the creeps up thread). Those people will be less androgynous, so I don't think you could have a society where EVERYONE is androgynous. Are people who are more visibly gendered discriminated against? Treated as equals? Tolerated, but thought of as nut jobs/freaks/hippies? That could be something you might want to explore. Also, obviously the language would evolve, becoming more gender-neutral. Names probably would be more gender-neutral, and the religious/moral crowd who opts out would probably have more gendered names as well.) You do have to explore this in some way, you can't just do, say, a mystery set in this world unless the androgynous society is relevant to the plot. From another angle, you might want to explore the processes involved with the genetics and everything. (If two biological males conceive, is there a process that keeps the baby healthy, and XX or XY instead of YY?) I'm asking because female-female reproduction is theoretically possible, and female parthenogenesis can happen in real-life (just not with humans) but male-male reproduction would have more factors to account for, namely: mitochondria and other organelles,the a fore mentioned YY scenario, etc.
The way I was planning to write it, before all this bru-haha started, was that the mass-androgyny had basically become so common in society that it was an Unusually Uninteresting Sight to a person from a secluded nation or culture. It would be like someone from the modern era explaining a car, a smartphone, or shampoo to a primitive society that hasn't gotten past the chariot. None of the main characters would have any clue how it worked. "Something about gene manipulation and nanomachines, the eggheads say".
In other words, by this time, it might not be something that everyone does, but it's common and growing steadily popular. At the point the story takes place, the androgynous people would be a marginal majority in the developed world.

Ouch: I failed again. I was being sincere in my sorry and the noting of my failure to be able to put my words together well. I think we just have a fundamental clash in styles.
"When your intent doesn't carry through to the reader, it is your fault as a writer, not theirs." That's one of my maxims. 
Just wanted to drop this link here: http://www.cracked.com/article_19780_5-gender-stereotypes-that-used-to-be-exact-opposite.html
It's a pretty interesting look at how, in some cases, just the past 100 years has shifted the perspective of genders and the stereotypes associated.
If I didn't make it clear in my first post with the magical reference to Nanomachines, I'm fine with the One Big Lie.
