Sorry, but scientifically speaking, men can never be women and vice-versa. Because humans reproduce via sexual, not asexual, reproduction, male gametes are small and motile, while females gametes are large and stationary. All of the hormones in the world can't change this, though the person taking them may eventually 'look' like the opposite sex. Yes, there are intersex people, but they are rare. Most transgenders are not intersex.
