The graphics below show the effects that estrogen may have on your body and an approximate timeline of these changes.
Estrogen has two main jobs:
1) It causes feminizing changes throughout the body.
2) It suppresses the production of testosterone. Some of the changes caused by estrogen arI permanent (they would remain if estrogen was stopped), and other changes are not.
Breast development caused by estrogen is permanent. Additionally, estrogen may irreversibly affect fertility. Desires for fertility should be considered prior to starting hormones, and for those seeking fertility preservation (or education about fertility preservation), referrals can be made to Lurie Children’s Fertility Preservation Program.
