Over the years, trans women have used various do-it-yourself treatments to induce lactation, with mixed results and only anecdotal reports of success.
"In some circumstances, modest but functional lactation can be induced in transgender women", authors of the study, Tamar Reisman and Zil Goldstein from the Mount Sinai Centre for Transgender Medicine and Surgery in NY, concluded in the results.
The findings were published in the journal Transgender Health.
Over the course of three and a half months, the patient's dosage of domperidone, micronised progesterone and estradiol was increased and decreased accordingly in addition to her use of the breast pump.
But there are fears drugs taken to induce lactation in a person born a man may be harmful to the child. "The human body is incredibly adaptable and milk production is a very robust system".
The woman, 30, said that she had decided even before her child was born that she would breastfeed.
The patient was already taking feminising hormones and got hold of a drug, domperidone, from Canada that...
The woman wanted to breastfeed for her partner.
Reisman and Goldstein acknowledge that more research is required in order to determine whether their method for inducing lactation can be achieved without the use of domperidone imported from other countries.
American watchdog the Food and Drug Administration has raised concerns over its "unknown risks" to breastfeeding infants. She continued breastfeeding along with formula feeds. Although this drug was originally developed to help treat stomach issues, it has been used to help increase milk production as well. For mothers who can not produce milk on their own, or for mothers who are adopting or using a surrogate, there is a protocol that includes hormones and pumping to induce lactation.
Her doctors started her on domperidone 10mg twice daily, which doubled after a month. A few claim that she was not the world's first "man" to breastfeed.
The patient then breastfed the baby during the first six weeks after birth, during which "the child's growth, feeding and bowel habits were developmentally appropriate".
She later supplemented feedings with formula because she was not producing enough milk, the study said.
"At the time of this article submission, the baby is approaching six months old", they write. She was also using a breast pump to be able to produce at least eight ounces of milk per day.
The woman, who is unnamed, was able to feed her baby breastmilk for six weeks, after undergoing hormone treatment.
