Among the characteristics that this tool allows you to select are categories of sex, gender, and sexuality. You should check all that apply. For example, a researcher might wish to gather information about how chest self-examinations are discussed with people who have substantial breast tissue, but do not identify as women. Such individuals include cisgender men with gynecomastia, transgender men who have not had chest reconstruction, and transmasculine people with nonbinary gender identities. The researcher in this case should check the boxes “Males or men,” “Transgender,” and “Gender nonbinary”
