>>936059109Breast development during male-to-female hormone therapy is still possible after the age of 30 โ though the degree and pace vary from person to person. Studies and personal accounts suggest:
Onset: First changes typically occur within 3โ6 months.
Maximum development: Full results can take 2โ3 years.
Size: Many trans women reach an A to small B cup. Larger growth is possible but less common and depends heavily on genetics, body structure, and the duration of hormone treatment.
Biological age can affect skin elasticity and how responsive the body is to estrogen, but it's definitely not a disqualifier. Even after 30, noticeable and satisfying breast development is very achievable.
