I can't find the links now (signal to noise ratio is low given the search terms I tried), but I've heard on numerous occasions that there are a few landmark studies where men were given estradiol and other estrogens and that resulted in behavior changes that ape the behavior patterns that most frustrate the author of this essay. Can anyone here point me to the experimental studies exploring the administration of sex hormone to the opposite gender and its effect on behavior? I've never read them myself and was curious as to their validity and the strength of the results.
