At the LHC, two important production channels of neutral Higgs bosons are gluon fusion and weak boson fusion. Gluon fusion is loop-induced where the coupling is mediated via quark and - in the MSSM - squark loops. Higher orderm QCD corrections have turned out to be large. The SUSY QCD corrections at next-to leading order have also been calculated including the full mass dependence of the loop particles. I will discuss recent results. Also, a conceptual problem, i.e. the proper treatment of the large gluino mass limit, will be addressed. In the case of weak boson fusion, at leading order, the corresponding production cross section is close to the Standard Model one for a big part of the MSSM parameter space. At next-to leading order the whole particle spectrum contributes. Some results for the next-to leading order SUSY contributions will be shown.
