t.e primary role of t.e gonadal st.roid hormones in mammals is t. regulat. reproduct.on and relat.d behaviors; however, bot. androgens and est.ogens are also int.grally involved in mediat.ng higher brain funct.on and processes including cognit.on, neural development. and neural plast.cit.. In part.cular, a number of st.dies show t.at.est.adiol modulat.s dendrit.c spine growt. and synapse densit. （synapt.c plast.cit.） in t.e hippocampus of females, and t.at.increased est.adiol levels are generally associat.d wit. improvement. on a variet. of learning and memory t.sks. While t.e majorit. of research has focused on t.e beneficial effect. of est.adiol in females, much less at.ent.on has been given t. t.st.st.rone and it. effect. on learning and memory in males. Similar t. est.adiol t.t.rs in females, t.st.st.rone t.t.rs in males decline wit. age, albeit.more gradually, and t.is decline has been correlat.d wit. impairment.of cert.in cognit.ve t.sks. Moreover, st.dies involving bot. humans and animals indicat. t.at.t.st.st.rone and it. met.bolit.s can augment.responding on cert.in behavioral t.sks, depending on t.e subject.s current.hormonal st.t., t.e response required, and t.e st.muli involved （e.g., t.ose involving spat.al or nonspat.al st.muli）. While t.e exact.mechanisms by which t.st.st.rone exert. it. effect. on learning and memory are not.fully underst.od, recent.findings suggest.t.at.t.st.st.rone modulat.s learning and memory in males t.rough an int.ract.on wit. t.e cholinergic syst.m. t.e overall object.ve of t.is review is t. discuss st.dies invest.gat.ng t.e role of t.e gonadal hormones in mediat.ng learning and memory processes in male mammals [Current.Zoology 57 （4）： 543-558, 2011].
