16.97

半擇除五者，亦除男女三無漏。景云：自有半擇迦亦成男女根，以不恒起名半擇迦。今據全無男女二根者為論，故言除五。若二形及以無形不得入聖，不成無漏根故。

"A paṇḍaka excludes five": also excluding male, female, and the three taintless. Jing says: Some paṇḍakas also accomplish the male and female faculties, but because they do not arise constantly, they are called paṇḍakas. Here the discussion is based on those who completely lack both male and female faculties; hence it is said to exclude five. If one has two physical genders or is without physical gender, one cannot enter noble status, because one does not accomplish the taintless faculties.
