An impressive study performed by objective Chinese researchers conclusively demonstrated that [[adult circumcision| circumcision]] reduces the glans sensitivity to vibration. "The test group were 1.97 +/- 0.71, 2.64 +/- 1.38, 3.09 +/-1.46 and 2.97 +/- 1.20 respectively before and 1, 2 and 3 months after circumcision, with significant difference between pre- and post-operation (P < 0.05).<ref name="young2008">{{REFjournal
