The comparison between male-to-female and female-to-male transitions went viral using Hunter Schafer and Elliot Page as examples, but the question requires great care. It is not correct to say that one transition “turns out well” and the other “turns out badly”, because each process depends on age, genetics, goals, medical treatment, and personal expectations.
Mayo Clinic explains that feminizing and masculinizing therapy produce different changes. Estrogen can alter skin, body fat, and breast development, while testosterone can deepen the voice, increase facial hair and muscle mass, and redistribute fat.
Surgeries, voice training, style, makeup, beard, hair, clothing, and transition time also play a role. That is why 2 famous people do not represent an entire community.
