"Possible"  "Side effect"  "Off lable drug"
Back in 1947 and 1948, a drug was given off lable  "to prevent miscarriages".  It is now known as a "monster maker" drug.  That drug enhanced the chances of an in-utero male becoming GID, but they had not come up with that definition then.  I was not miscarried, (obviously) but I had a severe flood of estrogen when I should have been starting to get my own T.  OK, I am here now and trans.  
When will they learn, not in the last 60 years it seems.
