Body contouring surgery usually involves suctioning fat cells from one part of your body (e.g. waist) and injecting them in another location (e.g. butt). The waist->butt transfer is also called a brazilian butt lift (bbl). This is by no means exclusive to trans women, but is sometimes used to deal with fat that doesn’t readily redistribute from hrt alone.

There are other procedures sometimes included with the jaw shaping in whats called facial feminization surgery (ffs) such as brow/eye socket shaping, a nosejob, or implants. A prominent “adam’s apple” can be smoothed out with a tracheal shave. Voices are usually modified through voice training, which teaches you to adjust your pitch and resonance without physical intervention, but there is a surgery for shortening the vocal cords.

There’s also a range of options that fall in the “bottom” surgery category, from an orchiectomy (removing the testes) to full gender/sex reassignment surgery, where they remove the external genitalia entirely, usually to create a vulva and/or vagina.
