Regarding the sex-dependant blessing shelo asani isha / she'asani kirtzono in the Birkot HaShachar, what does an androginus or a tumtum say? Do these people of ambiguous sex use the text normally used by males, that normally used by females, or some other formulation of this blessing?
The Mishna Brurah 46:18 writes that while a tumtum and androgynous are obligated in all mitzvos because of a doubt, they do not say "shelo asani isha," because they are a safek [Pri Megadim].
So I looked up the Pri Megadim (Eshel Avraham), who writes a tumtum and androgynous are chayiv in all mitzvos because of a safek; he writes that they do not say "shelo asani isha" because of a safek, and he then writes maybe they should say "kirtzono" (it is interesting the Mishna Brurah left that part out from his peirush).
It may very well be that the Mishna Brurah did this because of safek brachos lhakel (when in doubt, leave it out).
