The 30-year-old patient of theirs took hormones and an anti-nausea medication for three months, after which she was producing eight ounces of milk per day, the doctors reported in Transgender Health this January. Two weeks later, her partner gave birth and the baby’s growth and development progressed well during six weeks of exclusive breastfeeding from the transgender mom, after which the parents began supplementing with formula.
“There have been self-reported cases online of transgender women trying DIY regiments to induce breastfeeding, but this is the first case of induced functional lactation in the academic literature,” one of the doctors, Tamar Reisman of Mount Sinai hospital, tells The Guardian.
Boston Medical Center’s Joshua Safer, who did not treat the mom, tells New Scientist that transgender women tend to have “good breast development,” and that it’s not surprising this individual would be able to produce milk with the tissue. “This is very special. It will be very important for the many transgender women who want to breastfeed but do not feel they have the opportunity to do so.”
