To explore the characteristics of Chinese medicine constitution distribution of patients with infertility complicated with reproductive tract infections.Methods：Collected 656 cases of patients with infertility in the andrology outpatient clinic of Guangdong provincial hospital of traditional Chinese medicine from June，2016 to May，2018.Divided them into two groups according to the occurrence of reproductive tract infections，204 cases in the infection group and 452 cases in the control group.An instigation via Chinese medicine constitution scale and a statistical analysis were conducted respectively.Results：Dampness-heat constitution(54.9%)，yin-deficiency constitution(17.6%)and blood-stasis constitution(15.7%)mainly appeared in the infection group，while phlegm-dampness constitution(29.2%)，qi-depression constitution(19.9%)and dampness-heat constitution(17.3%)mainly appeared in the control group；there existed certain correlation between the distribution of constitution types and the course of disease.The total sperm count， total sperm motility，progressive sperms and morphologically normal sperms in the infection group were lower than those in the control group，differences being significant(P ＜ 0.05)；comparing the PH value and concentration of semen in both groups，there was no significant difference being found(P＞0.05).The level of seminal plasma elastase(SPE)and the value of sperm DNA fragmentation index(DFI)in the infection group were both higher than those in the control group，difference being significant(P＜0.05).In the infection group， the level of SPE and the value of DFI in patients of dampness-heat constitution， yin-deficiency constitution and blood-stasis constitution were higher than those in patients of qi-depression constitution(P ＜ 0.05)；the value of DFI in patients of yin-deficiency constitution and blood-stasis constitution was higher than that in patients of dampnessheat constitution(P ＜ 0.05).In the control group，the level of SPE and the value of DFI(except that in patients of qi-depression constitution)in patients of qi-depression constitution，phlegm-dampness constitution and dampness-heat constitution were respectively higher than those in patients of balanced constitution(P＜0.05).Conclusion：Qi-depression constitution， phlegm-dampness constitution and dampness-heatconstitution are susceptible to infertility； phlegmdampness constitution is most common among patients with infertility complicated with reproductive tract infections，which is intermingled with yin-deficiency constitution and blood-stasis constitution as disease develops.There exist differences in whether infertility is complicated with reproductive tract infections and the levels of SPE and DFI in patients with infertility of different constitution types.
