In fact, let's add to your list from topics already discussed in the past 20 pages. Maybe it will stop the flow of posters telling us all we are transphobic in our discussion:
What is unknown, and would what need to known before it could be recommended:
-in what quantities do synthetic hormones cross into breastmilk
-what potential impact would this have on offspring
-how does this compare to synthetic hormones such as contraceptives, for which we have a robust body of evidence for regarding safety
-how does the composition of milk produced in this way compare to milk produced by breastfeeding women
-based on the available evidence, is it possible for transwomen to safely contribute to the nutritional needs of their offspring
others;
-does a male breast, the seems to lack the receptors that a female breast has that connects to other systems of the female body, have the ability to replicate in any way, the breastmilk needed for the different stages of development.
-the maximum quantity that these males can achieve.
-what effect will this then have on a breastfeeding mother and their milk supply and their own breastfeeding.
-how will males entering into breastfeeding clinics affect women and their interaction in these clinics.
-how will those males who are doing this for any other reason be assessed? Including those males who simply want to produce a substance from their breasts or any other reason.
-further research on whether the female breast does in fact interact with the infant's health to produce more protection against illnesses etc. Is it ever going to be possible that a male body will do the same?
-is this diverting support needed to be invested to encourage more mothers to breastfeed?
I have not gone back through the thread, but maybe we should keep this list going if it is helpful.
