Another study about enhanced membership and satisfaction in venues where males and females interact:
“High Patient Satisfaction after Inflatable Penile Prostheses Implantation Correlates with Female Partner Satisfaction,” Ioannis Vakalopoulos, Spyridon Kampantais, Stavros Ioannidis, Leonidas Laskaridis, Panagiotis Dimopoulos, Chrysovalantis Toutziaris, Michail Koptsis, Gerard D. Henry, Vasileios Katsikas, Journal of Sexual Medicine, epub 2013. The authors, at Aristotle University of Thessaloniki, Greece and Regional Urology in Shreveport, LA, USA, report:
“69… [inflatable penile prosthesis] patients were evaluated for their pre- and postoperative erectile function and posttreatment satisfaction for themselves and their partners…. Regression analysis suggested a direct linear correlation of satisfaction between the sexual partners as a degree of satisfaction.”
