The possibility of abnormal steroid biosyntheses leading to in vivo formation of certain 14α-methyl steroids was discussed. In order to further evaluate this proposal, preparation of 14α-methyl steroidsrelated to the androgenic hormones was undertaken. Initially, a thirteen-step degradation sequence was developed for converting isocholesterol (crude lanosterol) to 3-oxo-17β-hydroxy-4,4,14α-trimethyl-5α-androstane
