In my field, there is mandatory radiation protection for pregnant women. If you start, you want to ask on the form for the (biological, birth) sex, and if it is not female you can simply skip the part where you inform the worker about rights and responsibilities in case of pregnancies. Honestly, I don't think you need to ask for any (gender|sex)-information in most cases, but it is often added out of completism. The only valid reasons are: - Self-presentation of the user, e.g. in a profile page -> allow the user to write whatever they want - Advertising, argh, but you often can't get around this. I don't know if advertisers care about how people identify or about trans people, but they probably want a simple m/f flag that fits enough people. - Medical or legal stuff
