Dr. Cicek and colleagues from Turkey present in page 112 (2) an important study about the association between seminal oxidation reduction potential (ORP) and conventional sperm parameters and shows that the presence of oligozoospermia, reduced progressive motilty or low total motility sperm count in sperm analysis should raise the suspicion of oxidative stress and warrants seminal reactive oxygen species testing and Dr. Groner et al. in page 185 (3) performed on Expert Opinon section an interesting mini-review about the effects of Covid-19 on male reproductive system and suggested that the involvement of the male reproductive system which could be a new route of the disease transmission. The virus has already been found in the semen of infected patients, but it remains to be assessed what impacts it has on male reproductive health. The editor in chief would like to highlight the following works too: Dr. Ouyang and collegues from China presented in page 23 (4) a nice systematic review about medical expulsive therapy and ESWL and shows that Adjunctive medical expulsive therapy with tamsulosin is effective in patients with specific stone size or location that received repeated ESWL. However, no well-designed randomized controlled trial that used computed tomography for the detection and assessment of residual stone fragments was found.
