>For example it can be important to know whether an individual can get pregnant or not. Out of curiosity, can you explain why you would want something like that?

You would then need a sub-item for the medical history, one can well be of the "right" gender (female) to become pregnant but be infertile nonetheless, whether from birth, due to some accident or due to the effects of another medical condition doesn't really matter.

And that would probably be the kind of information that you shouldn't be allowed to know, record and store online.
