摘　　要：目的探究老年男性血清睾酮值与性交频率的相关性。方法选取2015年10月1日至2020年5月30日重庆市第十三人民医院、重庆市人民医院、重庆医科大学附属永川医院、重庆市第四人民医院门诊部就诊(或健康体检)有固定性伴侣的普通老年(≥60岁)男性840例作为研究对象,检测其2年随访期内的0、6、12、18、24个月5个时间点血清总睾酮(TT)、游离睾酮(FT)值,同时采用问卷调查其性交频率。采用spearman相关分析评估643例完成随访的研究对象TT、FT值与性交频率的相关性。结果643例研究对象5个时间点TT值分别为(10.55±3.37)、(10.49±3.36)、(10.39±3.36)、(10.27±3.37)、(10.26±3.33)nmol/L,FT值分别为(7.60±2.39)、(7.62±2.34)、(7.48±2.39)、(7.34±2.45)、(7.33±2.40)pg/mL,性交频率分别为(2.7±2.2)、(2.8±2.1)、(2.5±2.0)、(2.3±1.8)、(2.2±1.8)次/月。TT、FT值与性交频率在5个时间点的相关系数分别为0.939、0.927、0.920、0.925、0.922和0.929、0.925、0.923、0.925、0.900,TT、FT值年均下降百分比与性交频率相关系数分别为-0.524、-0.593。结论老年男性血清睾酮值与性交频率呈正相关,性生活可减缓血清睾酮的增龄性下降。Objective To examine the correlation between serum testosterone levels and frequency of sexual intercourse in elderly males.Methods A total of 840 elderly males(≥60 years old)with regular partners,who went to the outpatient department(or had physical examination)in Chongqing 13th People′s Hospital,Chongqing General Hospital,Yongchuan Hospital affiliated to Chongqing Medical University,Chongqing Fourth People′s Hospital from October 1,2015 to May 30,2020 were collected as the study subjects.At 5 time points of 0,6,12,18 and 24 months after the start of the study,the levels of serum total testosterone(TT)and free testosterone(FT)were measured,and the frequency of sexual intercourse was investigated by questionnaire.Spearman correlation analysis was used to evaluate the relationship between TT,FT levels and sexual intercourse frequency of 643 subjects who completed the final follow-up.Results The TT values of 643 subjects at five time points were(10.55±3.37)nmol/L,(10.49±3.36)nmol/L,(10.39±3.36)nmol/L,(10.27±3.37)nmol/L and(10.26±3.33)nmol/L respectively;the FT values were(7.60±2.39)pg/mL,(7.62±2.34)pg/mL,(7.48±2.39)pg/mL,(7.34±2.45)pg/mL and(7.33±2.40)pg/mL respectively;the frequency of sexual intercourse were(2.7±2.2)times/month,(2.8±2.1)times/month,(2.5±2.0)times/month,(2.3±1.8)times/month and(2.2±1.8)times/month respectively.The correlative coefficients of TT,FT and sexual intercourse frequency were 0.939,0.927,0.920,0.925,0.922 and 0.929,0.925,0.923,0.925,0.900,respectively.The correlation coefficient between the annual decrease percentage of TT and FT and frequency of sexual intercourse were-0.524 and-0.593,respectively.Conclusion Serum testosterone level is positively correlated with the frequency of sexual intercourse in elderly males,and sexual life can slow down the aging decline of serum testosterone.
