In the very, very long term (i.e. years) it could shrink but nothing radical. You would need to have really low t for this to happen (i think Marianco said below 200). There is always "some" (if a little weak?). I have noticed some flaccid shrinkage but this is most likely due to the ratio of T/
DHT/E. I can still get and maintain an erection but it's hard work at times. In the shower (with the heat) i find it allot easier as it provokes and helps blood flow in the area. As long as you are getting even mild erections now and again thing's should be fine. Even a morning erection once a week/month is usually enough to keep thing's ticking over. On a side note it might be an idea to use Cialis (which Phil does) to keep blood flow good in the whole area if T is really low.
