When I can have the vaginoplasty surgery done? I have taken estradiol since April 2018 and had orchiectomy done.

I'm sorry for not getting back to you sooner. You can do vaginoplasty if 1. you are in good health2. BMI less than 27, now your BMI is 35.43. NO HIV hep B and CYou take hormones for a long time, and you can have surgery, but we suggest you make weight loss. around to be 160 pounds. You will have a good result and recover from

It sounds like you've thought this through and are ready to go. You should find a surgeon and start talking with him/her about next steps. The surgeon will probably want to meet with you in the clinic a few times to make sure you are ready and check the status of your progression. Most reputable surgeons will ask you to provide letters from mental health professionals and may require hair removal before your surgery. Hair removal can take around 6 months. Additionally you should get a physical and stop smoking (if you smoke) to make sure your body can handle the shock of a major surgery. Your weight puts you at a BMI of 35, which is at the upper end at which most providers will perform surgery. What is more important than the actual number of your BMI, is where you hold your weight. This can be determined by an exam in the office by the surgeon that you choose. You should make sure that you have a social network in place to support you during your recovery.
Your medical history is also important. We need to make certain that you are at peak health at the time of surgery. More information would be need to determine your candidacy for surgery, but the age is not an issue. We have performed vaginoplasties on patients that are older than you.
I hope this is helpful. Good luck!

Generally most insurances just require that you've been transitioned for at least 12 months and that you have 2 letters of support from your therapists.
