Objective:Testosterone deficiency may be a risk factor for lower urinary tract symptoms(LUTS),and there may be a causal ink between the emergence of LUTS and the incidence of late-onset hypogonadism(LOH).We perfomed an epidemiologic study to investigate the association between symptomatic late-onset hypogonadism(SLOH)and LUTS in middle-aged and elderly rural Chinese males.Methods:A total of 965 men completed a questionnaire and underwent a detailed physical examination.The Aging Males'Symptoms(AMS)scale was used to assess SLOH,and the International Prostate Symptom Score(IPSS)questionnaire was used to assess LUTS.Serum reproductive hormone levels of testosterone,sex hormone-binding globulin(SHBG)and luteinizing hormone(LH)were measured.Results:A total of 965 males(mean age:56.34±8.85,range:40-80 years)were recruited for the present study.A total of 20.93%(202/965)were diagnosed with SLOH.A total of 93.16%(899/965)had mild LUTS,5.18%(50/965)had moderate LUTS,and 1.66%(16/965)had severe LUTS.Among SLOH patients,13.40%(27/202)and 3.90%(8/202)had moderate and severe LUTS,respectively.Patients with severe LUTS had increased SHBG and LH compared with those with mild and moderate LUTS(P<0.01).Correlation analysis revealed that the AMS total score was positively correlated with the IPSS score(P<0.05).The prevalence of SLOH was significantly increased with LUTS severity In addition to the known effect of age,the results of mutiple regression analysis also showed that serum LH or SHBG appeared to have a weak link with SLOH and LUTS that requires etiological and biological clarification in our future study.Conclusion:In this cross-sectional analysis of SLOH and LUTS,LUTS severity was significantly associated with hypogonadism symptoms.Additionally,the prevalence of SLOH advanced with increasing LUTS severity.Serum SHBG or LH showed a positive correlation with SLOH and LUTS.
