I\'ve only just seen this, but it\'s quite interesting. If you are only doing it to help the
PMMA procedure it seems a little pointless when you consider that taking an alpha blocker for 3 or 4 days will achieve much the same thing. However For those who suffer from retraction especially in the winter months or post exercise like I do and don\'t want to pop pills every day, this could be a great option.
I\'m no expert but there may be a number of mechanism involved in retraction. One of the main causes is increased circulating adrenalin caused by anxiety or exercise , which closes down certain blood vessels to allow for the fight or flight response, preventing a flow of blood to your penis and thereby shrinking it. Alpha blockers prevent this. However the dartos muscle which is runs under your penile skin also contracts, typically you see a wrinkling of the shaft skin. I believe botox prevents the muscle from contracting.
