We discuss the associated W^\ifmmode±\else\textpm\fiH^\ensuremath∓ production in pp collision for the CERN Large Hadron Collider. A complete one-loop calculation of the loop-induced subprocess g\stackrel\ensuremath→gW^\ifmmode±\else\textpm\fiH^\ensuremath∓ is presented in the framework of the minimal supersymmetric standard model (MSSM), and the possible enhancement of the hadronic cross section is investigated under the constraint from the squark direct-search results and the low-energy precision data. Because of the large destructive interplay in the quark-loop contributions between triangle-type and box-type diagrams, the squark-loop contributions turn out to be comparable with the quark-loop ones. In particular, the hadronic cross section via gluon fusion can be extensively enhanced by squark-pair threshold effects in the box-type diagrams, so that it can reach the size of the hadronic cross section via the subprocess bb\ensuremath→W^\ifmmode±\else\textpm\fiH^\ensuremath∓ which appears at the tree level.
