Gender-affirmation surgery refers to a collection of procedures by which a transgender individual physically alters characteristics to align with their gender identity. While not all patients who identify as transgender will choose to undergo surgery, the surgeries are considered medically necessary and lead to significant improvements in emotional and psychological well-being.1 With increasing insurance coverage and improved access to care, more and more patients are seeking gender-affirming surgery, and it is incumbent for providers to familiarize themselves with preoperative recommendations and requirements.

Ob.gyns. play a key role in patients seeking surgical treatment as patients may inquire about available procedures and what steps are necessary prior to scheduling a visit with the appropriate surgeon. The World Professional Association of Transgender Health has established standards of care that provide multidisciplinary, evidence-based guidance for patients seeking a variety of gender-affirming services ranging from mental health, hormone therapy, and surgery.
Basic preoperative surgical prerequisites set forth by WPATH include being a patient with well-documented gender dysphoria, being the age of majority, and having the ability to provide informed consent.1
As with any surgical candidate, it is also equally important for a patient to have well-controlled medical and psychiatric comorbidities, which should also include smoking cessation. A variety of surgical procedures are available to patients and include breast/chest surgery, genital (bottom) surgery, and nongenital surgery (facial feminization, pectoral implant placement, thyroid chondroplasty, lipofilling/liposuction, body contouring, and voice modification). Patients may choose to undergo chest/breast surgery and/or bottom surgery or forgo surgical procedures altogether.
For transmasculine patients, breast/chest surgery, otherwise known as top surgery, is the most common and desired procedure. According to a recent survey, approximately 97% of transmasculine patients had or wanted masculinizing chest surgery.2 In addition to patients meeting the basic requirements set forth by WPATH, one referral from a mental health provider specializing in gender-affirming care is also needed prior to this procedure. It is also important to note that testosterone use is no longer a needed prior to masculinizing chest surgery.
Transmasculine bottom surgery, which includes hysterectomy, bilateral salpingo-oophorectomy, metoidioplasty, vaginectomy, scrotoplasty, testicular implant placement, and/or phalloplasty have additional nuances. Compared with transmasculine individuals seeking top surgery, the number of patients who have had or desire metoidioplasty and phalloplasty is much lower, which is mainly because of the high complication rates of these procedures. In the same survey, only 4% of patients had undergone a metoidioplasty procedure and 2% of patients had undergone a phalloplasty.2
In evaluating rates of hysterectomy with or without salpingo-oophorectomy, approximately 21% of transgender men underwent hysterectomy, with 58% desiring it in the future.2 Unlike patients pursuing top surgery, patients who desire any form of bottom surgery need to be on 12 months of continuous hormone therapy.1 They also must provide two letters from two different mental health providers, one of whom must have either an MD/DO or PhD. In cases in which a patient requests a hysterectomy for reasons other than gender dysphoria, such as pelvic pain or abnormal uterine bleeding, these criteria do not apply.
For transfeminine individuals, augmentation mammoplasty is performed following 12 months of continuous hormone therapy. This is to allow maximum breast growth, which occurs approximately 2-3 months after hormone initiation and peaks at 1-2 years.3 Rates of transfeminine individuals seeking augmentation mammoplasty is similar to that of their transmasculine counterparts at 74%.2 One referral letter from a mental health provider is also needed prior to augmentation mammoplasty.
Transfeminine patients who desire bottom surgery, which can involve an orchiectomy or vaginoplasty (single-stage penile inversion, peritoneal, or colonic interposition), have the same additional requirements as transmasculine individuals seeking bottom surgery. Furthermore, it is interesting to note that 25% of transfeminine individuals had already undergone orchiectomy and 87% had either undergone or desired a vaginoplasty in the future.2 This is in stark contrast to transmasculine patients and rates of bottom surgery.
Unless there is a specific medical contraindication to hormone therapy, emphasis is placed on 12 months of continuous hormone usage. Additional emphasis is placed on patients seeking bottom surgery to live for a minimum of 12 months in their congruent gender role. This also allows patients to further explore their gender identity and make appropriate preparations for surgery.
As with any surgical procedure, obtaining informed consent and reviewing patient expectations are key. In my clinical practice, I discuss with patients that the general surgical goals are to achieve both function and good aesthetic outcome but that their results are also tailored to their individual bodies. Assessing a patient’s support system and social factors is also equally important in the preoperative planning period. As this field continues to grow, it is essential for providers to understand the evolving distinctions in surgical care to improve access to patients.
