For many transgender individuals looking to see breast growth, the main interview is : “ How much breast development can I expect on HRT, and when will it start ? ”. Let ’ s take a look at summit development during the first year on anti-androgens and estrogen.

This article is describes the findings of the first base scientific study on breast development after HRT in trans women ( Breast Development in Transwomen After 1 class of Cross-Sex Hormone Therapy : Results of a prospective Multicenter Study ( 2017 ) – Christel Josefa Maria de Blok en co-authors ) This detailed study was performed on 229 trans women who completed their first base year of Hormone Replacement Therapy. Their ages ranged from 18 to 69, the medial age being 28 years at the start of the study .

When will my breasts start growing after starting on HRT?

Breast development largely occurred during the first 6 months on Hormone Replacement Therapy. The average increase over the first 3 months being 1.8 curium, and another 1.3 curium over the surveil 3 months. During the last 6 months, the average entire increase was lone 0.5 centimeter. It can hereby be concluded that main front growth takes position in the first six months of HRT. For most trans women, the size of the summit, nipple and areola will increase reasonably.

How much breast development can I expect on HRT?

After one year of HRT, the average increase in breast growth was 3.8 centimeter. When translating this to bra cup size, this mean around 50 % of all participating women had less than an AAA cup after one year. Less than 5 % of all women gained a cup size larger than an A cup. More follow-up research is needed to be able to accurately predict front increase in the follow year ( s ) of HRT .

Do factors like smoking, BMI, weight change, age,… influence breast development?

The short suffice is : no. In the analyze :

  • Breast growth does not vary in different age groups.
  • Breast growth does not vary based on weight change, weight gain or weight loss.
  • Obese trans women showed faster growth in the first months of HRT, but total breast-chest difference after 12 months was the same in normal weight, overweight and obese trans women.
  • Breast growth does not vary in smokers versus non-smokers.
  • Breast growth had a faster increase in trans women treated with transdermal estradiol for the first six months, but total breast development after one year saw no difference between the intake of oral or transdermal estradiol.

So we can conclude that the stream study shows a modest increase in breast-chest difference after 1 year of CHT, chiefly resulting in less than an AAA brassiere cup size. Age, weight change, fume, BMI, serum estradiol levels, and estrogen administration route did not predict total breast development after 1 year of CHT. Because of the meek results of HRT on breast development, many trans women seek to get a breast augmentation. It is advised to wait with surgery until you have been on HRT for 18 months .
