Yes,the clomiphene displays some intrinsic E/R deactivating capabilities.If you don't have any swelling/hard growths behind the nipples,then you'll likely be alright.Prolactin can often just give a slight fluid build-up in the arreola,and that doesn't equate to gyno.If you start to experience itchiness and extreme tenderness,coupled with small,pea sized lumps behind your nipple,then you have serious cause for concern.
