[Matrix] If you get a gender reassignment surgery in the Matrix, does anything happen to your real body?

Assuming you're still plugged in. Do the machines perform surgery on you? Do they artificially change the hormone levels in your body? Does your brain "make it real?" If everyone in the Matrix got a sex change at once, could that strain the caretaker systems?

This is a very interesting question (actually it is).

There is no canonical evidence to support the sexual reassignment of a person's body outside of the matrix. At least not in the terms you mean.

However, the character Switch may meet some of your criteria for gender selection or gender reassignment. This character changed genders upon entering the matrix. But there is no physical change to the body outside the matrix.

As an aside, author Robert A. Heinlein tackled some aspects of gender identification in his story *I Will Fear No Evil*.
