www.columbia.edudifferentiation of male gonad is dependent on the expression of SRY (sex reversal Y) = TDF (testes determining factor). This gene is expressed in the Sertoli cells of the male in a cell autonomous fashion. Its expression results in a cascade of events leading to the development of seminiferous tubules.

It is necessary for many cellular processes, including cell proliferation, inflammation, differentiation, and cell survival.--U.S. DEPARTMENT OF HEALTH AND HUMAN SERVICES
