Induced lactation in a transgender woman: case report

Abstract

Background

Breastfeeding offers significant health benefits, but its practice and success can vary. While research on induced lactation in cisgender women has been documented, there is limited research on lactation induction in transgender women.

Case presentation

A 50-year-old transgender woman undergoing hormone therapy and living with a pregnant partner sought to co-feed using induced lactation. After approval by the hospital ethics committee, a regimen of estradiol, progesterone, and domperidone was initiated, accompanied by nipple stimulation. Lactation was successfully induced and maintained, with milk composition analysis indicating high levels of protein and other key nutrients. This case, the seventh reported, highlights the complexity of lactation induction in transgender women, considering factors such as age, obesity, and insulin resistance. The nutrient profile of the milk suggests its suitability for infant feeding, despite some differences from typical human milk.

Conclusions

Induced lactation is feasible in transgender women, expanding the understanding of non-puerperal lactation and its potential in diverse family structures. Further research is warranted to optimize lactation induction protocols in transgender women.
