Computer Database Sex Gender codes

Oracle Database Tips by Donald BurlesonMay 7, 2015

Question:  I am working on a medical clinic database and I am told that I need more than male and female genders, to cover patients who are neither men nor women.  I have never heard of such a thing.  What are the accepted sex genders for computer databases?

Answer:  Yes, you're correct, many Oracle databases allow for more than just male and female genders for computer database gender codes.  It used to be that gender was either male or female, but that's not politically correct anymore.

Some States have adopted a multi gender code system.

  1. Male
  2. Female
  3. Male becoming female
  4. Female becoming male
  5. Eunuch, a castrated male.

The World Health Organization (WHO) has adopted more genders, with computer codes for Oracle medical databases that cover every possibility.

Here is the list of genders used by the WHO:

  1. Male
  2. Female
  3. Unknown:  No physical exam.
  4. Indeterminate:  Physical exam taken, but inconclusive.
  5. Male once Female:  Male gender re-assignment.
  6. Female once male: Female gender re-assignment.
  7. Male been both:  Gender re-assignment twice
  8. Female been both:  Gender re-assignment twice.
  9. Hermaphrodite:  Gender neutral, with some male and some female physical genital attributes.

Mr Garrison:  Male becoming female becoming male
