Some transgender men can breastfeed or chestfeed. Previous chest surgery, remaining milk-producing tissue and individual health can affect what is possible. A trans identity alone does not tell you how much milk someone can produce. CDC: Breast surgery and breastfeeding.
How chest surgery can affect milk supply
Surgery may affect milk ducts and nerves. The CDC explains that some people produce only part of the milk their baby needs after breast or chest surgery. Infant weight and feeding should be monitored, with additional feeding when needed. CDC: Breast surgery and breastfeeding.
Testosterone and feeding decisions
Testosterone may affect milk production. LactMed reports limited information from lactating trans men; the published observations do not establish one suitable plan for every parent or infant. Ask your prescriber and the baby’s clinician to review the actual medicine, dose and timing. LactMed: Testosterone during lactation.
Support should fit the parent and the baby
Before the birth, ask for access to a lactation professional familiar with your surgical history. Discuss what you would like to try, how supply will be assessed and what the backup feeding plan will be. Feeding choices should not be treated as a test of someone’s gender or commitment as a parent.
Questions to take to your appointment
- Could my particular surgery affect lactation?
- How will we know whether my baby is getting enough milk?
- Who can review my medicines while I am feeding?
Avoid promises that all people can make a full milk supply or that changing hormones will guarantee lactation.
