At a time when non-oral estrogens are easily available I cannot understand why anyone would take oral estrogens again, for feminization or even for menopause.

 
In addition to becoming feminized on your own, particular, personal terms, the basic objective when seeking feminizing hormone therapy should ideally be to improve the risks to benefits ratio of these hormones, in other words to minimize risks and side effects while at the same time tailoring the rapidity and effectiveness of feminization so as to match the desires of the individual patient.
