Biological males can take medications that cause them to produce breastmilk, and some Canadian breastfeeding specialists support sustaining babies on this milk. But pediatrician Dr. Michelle Cretella says major questions remain as to the safety of this practice.
Very few studies on the topic exist. The scientific literature includes only four case reports, and only two of them look at the composition of the milk—but not thoroughly enough, Cretella told The Epoch Times.

The infants ingest some of the drugs taken by the biological males to make them feminine and to help them lactate. The associated risks are largely unknown, Cretella said.
“The greatest problem with so-called male chest-feeding, however, is not a scientific matter, but an ethical one,” said Cretella, who works with the American College of Pediatricians, an organization critical of gender-identity policies that may harm children’s health.
