Catalysis of the reaction: 5-alpha-cholest-7-en-3-beta-ol + O2 = cholesta-5,7-dien-3-beta-ol + H2O2. Catalysis of the introduction of a double bond into a sterol molecule. Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from each of two donors, and molecular oxygen is reduced or incorporated into a donor. Catalysis of an oxidation-reduction (redox) reaction in which hydrogen or electrons are transferred from NADH or NADPH and one other donor, and the latter donor is dehydrogenated.
