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.

Outcome Measures
Primary Outcomes (1)
Level of presence od viral or bacterial infection, level of expression of SHH and VEGF in varicose vein wall. .
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.
one year after finishing recruitment
Study Arms (2)
microsurgery urology
EXPERIMENTAL20 patients with varicocele (grade II or III) undergoing subinguinal microsurgery varicocelectomy due to infertility and/or pain in the scrotum.
open general surgery
ACTIVE COMPARATOR20 patients (without varicocele) undergoing open hernia repair.
Interventions
During the procedure approximately 1cm long fragment of varicose vein will be taken for further investigation.
During the procedure approximately 1cm long fragment of spermatic cord vein will be taken for further investigation.
Eligibility Criteria
You may qualify if:
- in experimental arm - varicocele grade II or III and infertility and/or pain
You may not qualify if:
- in control arm: presence of varicocele in ultrasound before surgery
