BackgroundEnvironmental pollution and male infertility have become global public health problems. The presence of microplastics (MPs) has been detected in the human body, and it has also been demonstrated that MPs can cause damage to the reproductive system. Wuwei Fuzheng Yijing Decoction (WWFZYJ) is effective in treating male infertility. Therefore, we designed a clinical randomized controlled trial to observe the effect of WWFZYJ on the content of MPs and semen quality in male infertility patients, and to evaluate its security.MethodsIn this randomized controlled study, 66 eligible patients were randomly assigned in a 1:1 ratio to a treatment group (WWFZYJ Decoction) and a control group (Coenzyme Q10 tablets combined with vitamin E soft capsules) for 8 weeks. The content of MPs in semen, sperm DNA Fragmentation Index (DFI), and semen analysis (including sperm density, sperm count, forward motile sperm, sperm motility, etc) will be used as primary indicators, and Traditional Chinese Medicine (TCM) syndrome scores will be used as secondary indicators. Vital signs (such as respiration, heart rate, body temperature, blood pressure, electrocardiogram, etc), blood routine, urine routine, stool routine, liver function, and renal function will be used as safety indicators. The primary and secondary indicators will be performed at 0th and 8th week, and the safety indicators will be performed at 0th, 4th, and 8th week.DiscussionThis study will provide evidence for the efficacy and safety of WWFZYJ in treating male infertility and reducing the content of MPs in semen, and further explore the effects of MPs on male fertility.Copyright © 2022 the Author(s).
