Induction of lactation in a patient with complete androgen insensitivity syndrome.

Induced lactation is possible in chromosomally XY individuals with the use of pharmacological and non-pharmacological therapies. There are no standardised guidelines regarding the optimal regimen for induced lactation. Progesterone exposure to the breast is essential for ductal branching and alveolar maturation. In the published literature, induced lactation is more successful in transwomen and other XY individuals who have had prior progesterone exposure. The addition of progestogen to our patient's treatment regimen would have improved her chances of establishing successful lactation.
