Considering the large value of the top Yukawa coupling, we investigate the leading one-loop Yukawa electroweak corrections that can be induced by the top quark in a process such as Higgs production in association with a tagged bottom-antibottom pair at the LHC. At next-to-leading order these contributions are found to be small at the LHC both for the total cross section and for the distributions. In the limit of vanishing bottom Yukawa coupling where the leading order contribution vanishes, the process can still be induced at one-loop through the top quark transition. Though this contribution which can be counted as part of the next-to-next-to-leading order correction is small for Higgs masses around 120 GeV, it quickly picks up for higher Higgs masses. This contribution represents the rescattering of the top quarks and their decay into W's leading to Higgs production through WW fusion.
