yes, which i why i wondered whether Vasopressin is involved/ or could be involved in helping pois.If Vasopressin is involved than POIS-patients must have too much of it. Because edema (holding moisture) is one of the symptoms.
Vasopressin is released at the point of arousal.
i feel my problem starts at the point of arousal not the actual 'O' itself, as like you, i get some pois even without an O.
be interesting to find out if pois sufferers have a lower or higher production of Vasopressin during arousal(?)
I think everybody with POIS has POIS-symptoms even without an O. Maybe it has too do with the making of sperm? This proces might change the metabolism. And after an O there is a lot of sperm being made and released.
