Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Varicocele Viral Infection Bacterial Infections Sonic Hedgehog Expression VEGF Expression Procedure: subinguinal microscopic varicocelectomy Procedure: open hernia repair Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 40 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Basic Science
Official Title: The Search for Viral and Bacterial Etiology of Varicocele
Actual Study Start Date : July 2016
Estimated Primary Completion Date : December 2017
Estimated Study Completion Date : December 2018

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.
Procedure: subinguinal microscopic varicocelectomy
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.
Procedure: open hernia repair
During the procedure approximately 1cm long fragment of spermatic cord vein will be taken for further investigation.




Primary Outcome Measures :
  1. 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.
