Bikkurim4: 5
אֵינוֹ שָׁוֶה לֹא לָאֲנָשִׁים וְלֹא לַנָּשִׁים כֵּיצַד? אֵין חַיָּבִין עַל טֻמְאָתוֹ, וְאֵין שׂוֹרְפִין עַל טֻמְאָתוֹ, וְאֵינוֹ נֶעֱרָךְ, לֹא כָאֲנָשִׁים וְלֹא כַנָּשִׁים; וְאֵינוֹ נִמְכָּר בְּעֶבֶד עִבְרִי, לֹא כָאֲנָשִׁים וְלֹא כַנָּשִׁים; וְאִם אָמַר: ,,הֲרֵינִי נָזִיר שֶׁאֵין זֶה אִישׁ וְאִשָּׁה” — הֲרֵי זֶה נָזִיר.  רַבִּי יוֹסֵי אוֹמֵר: אַנְדְּרוֹגִינוֹס — בְּרִיָּה בִּפְנֵי עַצְמָהּ, וְלֹא הִכְרִיעוּ בוֹ חֲכָמִים אִם אִישׁ אִם אִשָּׁה. אֲבָל טוּמְטוּם — אֵינוֹ כֵן, אֶלָּא סָפֵק אִישׁ, סָפֵק אִשָּׁה.
[In] which [ways] is [the androgyne] not equal to men nor to women? They are not liable due to his tumah, they do not burn [terumah] on his tumah, and he cannot be the subject of an erech vow, not like men and not like women; he cannot be sold as a Hebrew slave, neither like men nor like women; and if [one] says, “I am a nazir that this [androgyne] is not a man and a not a woman,” he is a nazir.  R' Yose says: An androgyne is a creature unto it- self and the Sages could not decide whether he is a man or a woman. But a tumtum is not so; rather, he is possibly a man and possibly a woman.
