Medical treatment
Medical treatment of gender dysphoria might include:
Hormone therapy, such as feminizing hormone therapy or masculinizing hormone therapy
Surgery, such as feminizing surgery or masculinizing surgery to change the breasts or chest, external genitalia, internal genitalia, facial features, and body contouring
Some people use hormone therapy to seek maximum feminization or masculinization. Others might find relief from gender dysphoria by using hormones to minimize secondary sex characteristics, such as breasts and facial hair. Treatments are based on your goals, as well as an evaluation of the risks and benefits of medication use, the presence of any other conditions, and consideration of your social and economic issues. Many people also find that surgery is necessary to relieve their gender dysphoria.
The World Professional Association for Transgender Health provides the following criteria for hormonal and/or surgical treatment of gender dysphoria:
Persistent, well-documented gender dysphoria.
Capacity to make a fully informed decision and consent to treatment.
Age of majority in a given country or, if younger, follow the standard of care for children and adolescents.
If significant medical or mental concerns are present, they must be reasonably well controlled.
In addition, the other link I embedded spoke to the potential for genetic mutations to be 'causative' for "Gender Dysphoria"...be sure to read that as well. Again, there are many unknowns, so folks shouldn't dig their heels in and rely on what they "like" or "don't like".
