She hadn't undergone any gender-affirming surgery, such as orchidectomy (the surgical removal of testicles) or vaginoplasty (the construction or reconstruction of the vagina).
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.
Writing in the Transgender Health journal, specialists from the Mount Sinai Centre for Transgender Medicine and Surgery said: "She explained that her partner was pregnant but not interested in breastfeeding, and that she hoped to take on the role of being the primary food source for her infant".
"The transgender woman came to our clinic with the goal of being able to breastfeed her adopted infant". She was told to increase her medication intake, including domperidone, which she obtained from Canada.
She was also given a breast pump to simulate a feeding child, in a bid to further boost milk production.
Hamlin takes 6th place, leading United States luge women
With five world cup individual wins to her credit, Britcher is the all-time wins leader in US history for singles luge athletes. A tweet posted to Davis' Twitter account said the process by which Hamlin won the honor was executed "dishonorably".
"We believe that this is the first formal report in the medical literature of induced lactation in a transgender woman", said Tamar Reisman, endocrinologist and Assistant Professor at the varsity. The report doesn't mention if she continued the treatment during breastfeeding. And during that time, the baby's paediatrician reported that the child's growth, feeding and bowel habits were developmentally appropriate.
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. After three months, the patient was reportedly producing 8 ounces of milk a day. "At the time of this article submission, the baby is approaching 6 months old". However, the woman had to supplement breastfeeding with formula later one because she wasn't producing enough milk to fill the baby's appetite.
"This is a very big deal", Joshua Safer, of Boston Medical Center who was not involved with the treatment, told New Scientist. She said she empathizes with transgender parents, but trying to induce lactation is "not something I would do".
The treatment has been hailed as a breakthrough by some, but doctor and transgender woman Madeline Deutsch, said that the science behind it is lacking.
The anonymous US trans woman continued for at least six months, giving the baby a mixture of formula and breast milk. "Many transgender women are looking to have as numerous experiences of non-transgender women as they can, so I can see this will be extremely popular", he said.
