Breast growth, erectile dysfunction and decreased libido in a 60-year-old male who drank about six pints of soy milk per day. With no other cause indicated. His symptoms ceased after he stopped consuming all this soy.
- 0dayz 3y agoSorry but this is not a study, it's a case report. As they could not determine his testosterone levels before he started to ingest soy milk, it's impossible to know if the man was already suffering from low testosterone. And in my sources they have studies that specifically look into people that are 60+ and there was no such link found.
- ttbooms 3y agoIn the papers you linked, I can't see any studies where the subjects were consuming an equivalent amount of soy to the 60-year-old soy milk enjoyer. Looks to be much less in all of these trials. So it seems the question hasn't been conclusively answered. But the case study hints at the possibility of an excessively high intake of soy having an estrogenizing effect, even if we don't know why. Maybe he had some particular configuration of gut bacteria that helped this process along, or something. More research needed.
- 0dayz 3y agoNo because your source isn't a study but a case report. And again even if we take your source at face value it's a 60 year old man (which mean less testosterone production) who consumed an absurd amount not something most people will consume.
