GRS meaning in Medical ?

Sex reassignment surgery (SRS), also known as gender reassignment surgery (GRS) and several other names, is a surgical procedure (or procedures) by which a transgender person's physical appearance and function of their existing sexual characteristics are altered to resemble those socially associated with their identified gender. It is part of a treatment for gender dysphoria in transgender people. The term is also sometimes used to describe surgical intervention for intersex people.

Professional medical organizations have established Standards of Care that apply before someone can apply for and receive reassignment surgery, including psychological evaluation, and a period of real-life experience living in the desired gender.

Feminization surgeries are surgeries that result in anatomy that is typically gendered female. These surgeries include vaginoplasty, feminizing augmentation mammoplasty, orchiectomy, facial feminization surgery, reduction thyrochondroplasty (tracheal shave), and voice feminization surgery among others.

Masculinization surgeries are surgeries that result in anatomy that is typically gendered male. These surgeries include chest masculinization surgery (top surgery), metoidioplasty, phalloplasty, scrotoplasty, and hysterectomy.

In addition to SRS, patients may need to follow a lifelong course of masculinizing or feminizing hormone replacement therapy.
