Ok, you must quit before a phallo, period no ifs, and or buts. The jury is out on top and meta unless you are getting nipple grafts and meta if grafts are used. Now the logic, phalloplasty requires multiple grafts that must heal properly if you want to have more then a stub where your penis died, multiple skin grafts and possible loss of donor site (your arm). Smoking slows that growth of new cells and increases DVTs. The new penis has a limited amount of time to recover and smoking increases that time well past the survival point of the new tissue. I have never heard of a sucessful case where the patient didn't quit. You are also immobile for a very long time and that my dear is how people generally get DVTs. No reputable surgeon will preform flap microsurgery on a patient that still has nicotine in their system because that would promise a poor result for something they are putting upwards of 12 hours of surgery into. Jay you have the right to smoke all you want but the surgeon also has the right to say you are a poor candidate for surgery and refuse you and if they didn't that would be unethical. Frankly it is disturbing that you are considering this surgery without a basic idea of what can and can't be done and that you are demanding your own way of treatment. You can not have your cake and eat it too. I didn't quit for my top or hysto and frankly it took me forever to heal properly. I am in discussion with surgeons about bottom surgery and everything single one has made it quite clear if I have nicotine in my system (they will test me) prior to the surgery then it will be canceled. As soon as I have a date I am quiting however hard it is going to be, it is harder by far to live without a penis and if you can't say the same then their are bigger issues then smoking. If you have doubts type "microsurgery", "smoking" and "healing" into google and you can read probably 100s if not 1000s of articles saying exactly what I have said.
Oh yes in terms of T, DVTs and smoking. I can't really say whether there is a need. I had 2 DVT before T both caused by trauma. I have had 5 or 6 DVTs since T though because I forgot to aspirate and injected into a vein. For reference T in vein= DVT so always make sure there is no blood in the syringe when you pull out. I have no way of knowing whether smoking helped cause those DVTs but I have smoked for all but 1 of my DVTs. I am high risk for DVT so even though I will quit I still have to be on blood thinners and these legging that keep the blood flowing in my legs. Try to remember that T thickens your blood increasing your risk of DVTs and smoking also can have this effect. Hard to say what the risks are but smoking has a whole lot of other risks too.
