    what is the real cause of finasteride /dutasteride induced gynecomastia ?

    When you block one of several possible pathways (such as T to DHT) other pathways may compensate/up regulate, and 5ar inhibitors often sees a bump in E2 as that pathway has more substrate being pushed due to 5ar inhibition.
