How long it takes for breast growth on hormone therapy varies from person to person. On average, most experience some breast bud development within 3-6 months, gradual growth over 2-5 years, and maximum growth within 3-7 years. However, many factors impact timeline and results.
Key influences include:
- Age at start of therapy - Younger individuals tend to experience faster, more robust growth
- Hormones used and dosing
- Genetics and ethnicity
- Lifestyle choices like nutrition, exercise, sleep
Below is a rough timeline after initiating hormone therapy:
- 1-3 months: Breast buds form, slight breast tissue growth
- 3-12 months: Noticeable breast growth continues
- 1-2 years: Most growth occurs during this time, including fat deposition
- 2-5 years: Breasts continue maturing with progesterone effects
- 3-7 years: Maximum size and shape realized for most
However, breast development is highly variable. Some may reach final size faster while others experience growth for longer durations.
Factors accelerating growth include:
- Starting hormones at younger age (<25 years old)
- Higher estrogen dosing
- Progesterone addition
- Genetics for curvy body shape
Factors possibly slowing growth:
- Starting hormones at older age
- Lower estrogen dosing
- High testosterone levels
- Thin body composition
While waiting can be challenging, try focusing less on breast size timeline. Instead celebrate each small sign of feminization. Your patience, self-care and positive outlook will benefit development.
