Well, if you wish to be specific, standard US prices are about $30,000 for Male to Female and $70,000 for Female to Male. Hormone therapy is considered a seperate cost from the surgery.
TS Specialty centers however are cheaper than that. Plastic surgeons charge for essentially how much their time is worth, how much they think their cutsomer can pay, and how esoteric the operation is. Specialty places can process patients quicker, tend to be working class patients, and for them it's near routine, so it's cheaper there. That $5,000 quote is old however, it's probably $8,000 now. That's a hosiptal in Wisconsin, or somewhere upper mid north USA if I remember right.
If the combination doesn't make sense, know that most of the actual costs come from anisthetics, stay/care, and insurance. It's very economical for a doctor to do both while the patient is out.
The actual operation itself is only a few hours, then the patient is released the next day and advised on how to use stints. For those that travel to a specialty clinic, they generally stay two weeks there and consider it a recovery vacation.
