function Sex= Choose_Sex
disp('Choose Sex or Gender to preview Health Data on')
Sex = menu('Choose sex','Female','Male');
if Sex == 1
disp('Female')
elseif Sex == 2
disp('Male')
end
while Sex == 0
disp('Error Choose sex,');
Sex = menu('Choose sex','Female','Male');
end
How can i let the answer of Sex show as string female or male instead of double 1 or 2

while true
choice = menu(etc)
if choice == 1
Sex = "Female";
break;
elseif choice == 2
Sex = "Male";
break
end
fprintf('What??\n');
end

still show sex as a box in a fprintf statement

No it does not. The only fprintf() statement there is for the case that neither male nor female is chosen, and in that case it displays a hard-coded string with no box.
You might perhaps have a different fprintf() statement that you have not shown us.

You can use a cell array of character vectors (formerly known as a cell array of strings) to store the options.
function Sex= Choose_Sex
disp('Choose Sex or Gender to preview Health Data on')
Sexes = {'Female' 'Male'}; % 'Sexes' is a cell array of character vectors
Sex = menu('Choose sex',Sexes{:});
if Sex > 0
disp(Sexes{Sex});
end
while Sex == 0
disp('Error Choose sex,');
Sex = menu('Choose sex',Sexes{:});
% Edit: I guess you want to display the sex here too
if Sex > 0
disp(Sexes{Sex});
end
end

Return the character vector from the Choose_Sex function rather than the index Sex:
function Sex= Choose_Sex
disp('Choose Sex or Gender to preview Health Data on')
Sexes = {'Female' 'Male'}; % 'Sexes' is a cell array of character vectors
Sex = menu('Choose sex',Sexes{:});
if Sex > 0
disp(Sexes{Sex});
end
while Sex == 0
disp('Error Choose sex,');
Sex = menu('Choose sex',Sexes{:});
% Edit: I guess you want to display the sex here too
if Sex > 0
disp(Sexes{Sex});
end
end
Sex = Sexes{Sex}; % return the character vector, not the index
Then, when calling the function and printing the result, use the %s format specifier for strings/character vectors:
selected_sex = Choose_Sex();
fprintf('Selected Sex is %s',selected_sex);

Try this:
function Sex= Choose_Sex
disp('Choose Sex or Gender to preview Health Data on')
selectedButton = menu('Choose sex','Female','Male');
Sex = 'Male'; % Initialize.
if selectedButton == 1
disp('Female')
Sex = 'Female';
elseif Sex == 2
disp('Male')
end

It DOES run. I just tried it again. It's now attached. If it doesn't run for you, then attach your code.
