Majorana neutrino masses can originate either at the tree level (type-I, II or III seesaws) or can be radiatively induced. The latter option naturally requires order TeV BSM fields, thus leading to -in principle- testable neutrino mass generation mechanisms. Based on a two-loop systematic classification of the dimension five effective Weinberg operator, in this talk I will discuss the different realizations one can envisage for neutrino mass generation at the two-loop order.
