Answers in the survey might revolve largely around differences between the sexes in anatomy (including genitalia of course), or might even extend to sex-specific or sex-biased roles in reproduction (which sex gives birth, lactates, is typically the primary carer, and so forth).

Males produce sperm (the name for the smaller sex cells) and females produce ova/eggs (the name for the larger sex cells), but these are just names that we have chosen to give to the sexes and their sex cells - we could just as well call them something entirely different.
