An NHS trust has said that breast milk produced by trans women who were assigned male at birth is as good for babies as that produced by a mother who has given birth.

In a letter to campaigners, the University of Sussex Hospitals NHS Trust (USHT), said that the milk produced by trans women after taking a combination of drugs is “comparable to that produced following the birth of a baby”. ...

A drug is required to lactate, such as domperidone, which is often prescribed to women struggling to breastfeed, and helps to stimulate the production of prolactin – a separate hormone that tells the body to produce milk.

Domperidone, also known by the brand name Motilum, was not intended for this, but is prescribed off-label by doctors, despite the manufacturer, Janssen, itself recommending against it because of possible side effects to a baby’s heart.
