Personally speaking I think we all forget that the body makes hormones by itself. We should for example remember that PM is a very powerful Estradiol mimic and Estradiol potently suppresses tge body's production of other hormones such as testosterone but also e.g. progesterone. Adult males produce more progesterone normally than a pubescent girl. I suspect that one of the the things that happens when you stop suddenly is you get a surge of progesterone along with testosterone. T blocks estroge n receptors but doesnt block progesterone receptors so maybe your getting a short burst of duct growth after all the estrogen induced gland growth.
