The Search for Viral and Bacterial Etiology of Varicocele (ViBaVa)
March 5, 2019 updated by: Medical University of Warsaw
This study is to answer the question is there any relationship between viral ( HSV 1 , HSV 2 , HPV 6/11, CMV, HHV 6 , HHV 8, BKV) or bacterial (Porphyromonas gingivalis, Treponema denticola, Tannerella forsythia, Fusobacterium nucleatum) infection and occurrence of varicocele in men.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
|---|---|
|
Experimental: microsurgery urology
20 patients with varicocele (grade II or III) undergoing subinguinal microsurgery varicocelectomy due to infertility and/or pain in the scrotum.
|
During the procedure approximately 1cm long fragment of varicose vein will be taken for further investigation.
|
|
Active Comparator: open general surgery
20 patients (without varicocele) undergoing open hernia repair.
|
During the procedure approximately 1cm long fragment of spermatic cord vein will be taken for further investigation.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Level of presence od viral or bacterial infection, level of expression of SHH and VEGF in varicose vein wall. .
Time Frame: one year after finishing recruitment
|
Qualitative and quantitive analysis (presence and concentration - µl or U/µl in two different laboratory tests.) to detect genetic material (DNA, mRNA) of bacteria/viruses will be performed.
The outcomes from both gropus will be compared.
