Hormone therapy plays a critical role in gender reassignment from male to female. A transsexual in the hormone therapy stage is in effect going through a second puberty, causing the body to change. For a man, the amount of estrogen during therapy is comparable to that of a woman during her menstrual cycle, while the amount of testosterone in the body is actually less than what is produced by a woman. The maximum amount of time hormone therapy lasts is approximately 4 to 5 years, but many transsexuals choose to have sexual reassignment surgery before this. Transsexuals who choose to remain non-operative must choose other options in order to continue their hormone therapy after this time period.
