If such a child was Jewish and accepted as female upon birth, several interesting situations could occur:
- The person was married to a male after age 12, only to then turn into a male.
- The person, thought to be halachically an adult (since girls mature at age 12) performed acts of halachic bearing, only to then turn into a male and therefore losing status as adults (since males mature at 13).
- The person would supposedly need a circumcision, but at what point in the gradual transition would it be performed? (Asked by CashCow.)
What would the halachic implications be?
