Transgender Transition: Breast Enhancement Surgery. This episode explains why transitioning transwomen go on hormone therapy and why breast enhancement surgery is often needed. Transwomen want to look like other women and wear feminine clothing but this requires hormone therapy to reshape the body and, in particular the breasts. When hormone therapy results for breast development is inadequate, about half of transitioning transwomen get breast implants for enhancement. The episode also describes what it was like for your Transgender Scientist to get breast enhancement surgery.
