was the first known recipient of male-to-female sex reassignment surgery, in Germany in 1930. She was the subject of four surgeries: one for orchiectomy, one to transplant an ovary, one for penectomy, and one for vaginoplasty and a uterus transplant. However, she died three months after her last operation. Christine Jorgensen was likely the most famous recipient of sex reassignment surgery, having her surgery done in Denmark in late 1952 and being outed right afterwards. She was a strong advocate for the rights of transgender people. Another famous person to undergo male-to-female sex reassignment surgery was Renée Richards. She transitioned and had surgery in the mid-1970s, and successfully advocated to have transgender people recognized in U.S sports. The first male-to-female surgeries in the United States took place in 1966 at the Johns Hopkins University Medical Center. The first physician to perform sex reassignment surgery in the United States was the late Elmer Belt, who did so until the late 1960s. In 1997, Seargent Sylvia Durand became the first serving member of the Canadian Forces to transition from male to female, and became the first member of any military worldwide to transition openly while serving under the Flag. On Canada Day of 1998, the military changed her legal name to Sylvia and changed her sex designation on all of her personal file documents. In 1999, the military paid for her Sex Reassignment Surgery. Sylvia continued to serve and got promoted to the rank of Warrant Officer. When she retired in 2012, after more than 31 years of service, she was the assistant to the Canadian Forces Chief Communications Operator. As of 2014, Canada allowed transgender people to serve openly in its military forces. The policy of inclusion is still in effect in 2020. In 2017, for the first time, the United States Defense Health Agency approved payment for sex reassignment surgery for an active-duty U.S. military service member. The patient, an infantry soldier who identifies as a woman, had already begun a course of treatment for gender reassignment. The procedure, which the treating doctor deemed medically necessary, was performed on November 14 at a private hospital, since U.S. military hospitals lack the requisite surgical expertise.
Genital surgery
When changing anatomical sex from male to female, the testicles are removed, and the skin of foreskin and penis is usually inverted, as a flap preserving blood and nerve supplies, to form a fully sensitive vagina. A clitoris fully supplied with nerve endings can be formed from part of the glans of the penis. If the patient has been circumcised, or if the surgeon's technique uses more skin in the formation of the labia minora, the pubic hairfollicles are removed from some of the scrotal tissue, which is then incorporated by the surgeon within the vagina. Other scrotal tissue forms the labia majora. In extreme cases of shortage of skin, or when a vaginoplasty has failed, a vaginal lining can be created from skin grafts from the thighs or hips, or a section of colon may be grafted in. Surgeon's requirements, procedures, and recommendations vary enormously in the days before and after, and the months following these procedures. Since plastic surgery involves skin, it is never an exact procedure. Cosmetic refining to the outer vulva is sometimes required. Some surgeons prefer to do most of the crafting of the outer vulva as a second surgery, when other tissues, blood and nerve supplies have recovered from the first surgery. This relatively minor surgery, which is usually performed only under local anaesthetic, is called labiaplasty. The aesthetic, sensational, and functional results of vaginoplasty vary greatly. Surgeons vary considerably in their techniques and skills, patients' skin varies in elasticity and healing ability, any previous surgery in the area can impact results, and surgery can be complicated by problems such as infections, blood loss, or nerve damage. Supporters of colovaginoplasty state that this method is better than use of skin grafts for the reason that colon is already mucosal, whereas skin is not. Lubrication is needed when having sex and occasional douching is advised so that bacteria do not start to grow and give off odors. Because of the risk of vaginal stenosis, any current technique of vaginoplasty requires some long-term maintenance of volume by the patient using a vaginal expander, or vaginal dilation using graduated dilators to keep the vagina open. Penile-vaginal penetration with a sexual partner is not an adequate method of performing dilation. Daily dilation of the vagina for six months in order to prevent stenosis is recommended among health professionals. Over time, dilation is required less often, but it may be required indefinitely in some cases. Regular application of estrogen into the vagina, for which there are several standard products, may help, but this must be calculated into the total estrogen dose. Some surgeons have techniques to ensure continued depth, but extended periods without dilation will still often result in reduced diameter to some degree, which would require stretching again, either gradually, or, in extreme cases, under anaesthetic. With current procedures, trans women are unable to receive ovaries or uterus. This means that they are unable to bear children or menstruate, and that they will need to remain on hormone therapy after their surgery to maintain female hormonal status and features.
Other related procedures
Facial feminization surgery
Occasionally these basic procedures are complemented further with feminizing cosmetic surgeries or procedures that modify bone or cartilage structures, typically in the jaw, brow, forehead, nose and cheek areas. These are known as facial feminization surgery or FFS.
Breast augmentation
is the enlargement of the breasts. Some trans women choose to undergo this procedure if hormone therapy does not yield satisfactory results. Usually, typical growth for trans women is one to two cup sizes below closely related females such as the mother or sisters. Oestrogen is responsible for fat distribution to the breasts, hips and buttocks, while progesterone is responsible for developing the actual milk glands. Progesterone also rounds out the breast to an adult Tanner stage-5 shape and matures and darkens the areola.
Some MTF individuals may elect to have voice surgery, which alters an individual's vocal range or pitch. However, this procedure carries the risk of impairing a trans woman's voice forever, as experienced by transgender economist and author Deirdre McCloskey. Since estrogen alone does not alter a person's vocal range or pitch, some people take the risk that comes along with voice feminization surgery. Other options, like voice feminization lessons, are available to people wishing to speak with less masculine mannerisms.
Tracheal shave
A tracheal shave procedure is also sometimes used to reduce the cartilage in the area of the throat and minimize the appearance of the Adam's apple in order to assimilate to female physical features.
Buttock augmentation
Some MTF individuals will choose to undergo buttock augmentation because anatomically, male hips and buttocks are generally smaller than those presented on a female. If, however, efficient hormone therapy is conducted before the patient is past puberty, the pelvis will broaden slightly, and even if the patient is past their teen years, a layer of subcutaneous fat will be distributed over the body, rounding contours. Trans women usually end up with a waist to hip ratio of around 0.8, and if estrogen is administered at a young enough age "before the bone plates close", some trans women may achieve a waist to hip ratio of 0.7 or lower. The pubescent pelvis will broaden under estrogen therapy even if the skeleton is anatomically masculine.
