The Ugly Truth of Male Breastfeeding

"Here's another debunking adventure into the world of safety and considerations in male breastfeeding. This adventure was spurred on by the ongoing claims made by a transwoman on Twitter who claims that transwomen are just as capable, if not better, than females when it comes to breastfeeding infants. "
"The first problem is that this transwoman was able to produce 8oz of milk per day. For reference, a newborn will drink between 4-6oz a day for the first 2 days of life. By day 3, an infant will drink up to twice that much. By 2 weeks of age, the infant will drink between 2-3 oz per feeding with 8-12 feedings a day. The 6 oz each day will nowhere near cut it, which is why by the time the infant was 6 weeks old, they were supplementing feeding with formula and eventually switching to formula being the primary source of nutrition.[2]
But, on top of that, the primary medication used to induce prolactin levels is called domperidone, which was determined not to be safe for infants or children because of lack of efficacy. This was also done after reports of cardiotoxicity at pediatric doses. This report highlights the significant risk for populations with reduced liver function and electrolyte instability, of which infants fall under both categories.[3]
In addition, the FDA recommended against using domperidone for breastfeeding in 2004 because the medication is excreted in breast milk, causing unknown risk in infants.[4]"
"The results of the analysis were that the milk produced was within a reasonable range of the standard numbers with the exception of one: fat. The average fat for breastfeeding women was 3.4 g/dL. The amounts collected from the transwoman's samples ranged from 4.1-6.2 g/dL. The amount of fat in milk that the infant receives is important for the growth and development of the infant, however too much fat can also result in health problems early in life including obesity and diabetes.[7]
Perhaps the most concerning part of the study is that it included a statement from the transwoman about how affirming the act of breastfeeding was and the emotional and bonding benefits for the transwoman. While bonding to the infant is important, such bonds can be achieved through skin to skin contact and does not require breastfeeding."

Why can't a male develop identical breasts to a female, since breast tissue growth is sensitive to high estrogen exposure in both sexes?
This has to do with what's called the hypothalamic-pituitary-gonadal axis, or HPG. This axis forms an important brain-to-gonad feedback loop at puberty that causes the masculinization or feminization of the body, depending on the gonad type you have.
Many of the effects will be permanent (so called organizational effects).
For females, the HPG axis is specifically the HPO axis (O for ovarian). At puberty, the cyclical production of estrogen from the ovaries and growth hormone from the pituitary creates a cascade of events that "transform the rudimentary mammary structure into the mammary gland."
Due to progressive elongation and branching of the ducts through puberty, thanks to the HPO axis, an extensive duct network of branches is formed. These branches will lead back to what's called the terminal duct lobular units (TDLUs), the structures that produce milk during lactation. Such structures are ultimately built thanks to the HPO axis, but they remain more dormant until pregnancy and childbirth.
For males, on the other hand, the activation of the HPT (testes) axis and the high amount of testosterone from the testes inhibits any major duct development. Males can develop extra, dense breast tissue (known as gynecomastia) through excess estrogen or other hormonal dysregulation such as cross-sex hormone use. But this is as far as the development can go. Males will not develop extensive lobules for milk production nor extensive duct branching.
The extensive and complex duct structures seen in the female breast cannot be formed in the male due to the profound impact of the two different sex-specific HPG axes across development (activation of HPT in the male and absence of the HPO)."
