To explore the diagnose and treatment rules of acupuncture and moxibustion in treating functional impotence，and to propose treatment protocols after combining the clinical experience and the characteristic of pelvic floor nervus.Methods:Literatures related to functional impotence treated by acupuncture and moxibustion in CNKI(1979—2014)，Wanfang Date(1990—2014)，CHKD (1979—2014)，PubMed(1979—2014) were retrieved，and the intervene measures related to acupuncture and moxibustion，clinical characteristics of syndrome differentiation and acupuncture points selection method，frequency，total treatment time，treatment effect，follow-up study and safety in treating functional impotence by acupuncture and moxibustion were summarized and analyzed.Results:Among the included 38 articles，studies involving acupuncture treating functional impotence took account for 42.11%(16/38); 52.63% of the studies used acupuncture points selection method by differentiation of disease; the main acupuncture points were Guanyuan (RN4，55.26%，21/38)，Shenshu (BL23，42.11%，16/38)，Sanyinjiao (SP6，39.47%，15/38)，Zhongji (RN3，28.95%，11/64)，Ciliao (BL32，28.95%，11/38)，Mingmen (DU4，21.05%，8/38).The treating frequency of 60.53% of the studies was once a day; the total treatment time of 13.16% studies was 8 weeks; the effective rate varied from 78% to 100% with different intervene measures; the follow-up rate was only 10.53% (4/38); there was not any adverse reactions reported in these literatures.Conclusion:Acupuncture and moxibustion treating functional impotence has high efficient，but most of the literatures were not randomized，controlled and follow-up studies，so it needs higher quality researches to confirm the actual effective value of acupuncture and moxibustion treating functional impotence.Recommended program is treating functional impotence by deeply inserting Zhongliao(BL33) acupoint once a day for the first 5 weeks and once every other day in the following 3 weeks.
