Removal of red light minimizes methylene blue-stimulated DNA damage in oesophageal cells: implications for chromoendoscopy.

abstract：:Male infertility is a relevant social and medical problem. Male infertility is mostly caused by genetic disorders. The purpose of the study was to analyze the correlation of chromosome aberrations, as well as DNA fragmentation and various manifestations of spermatogenesis disorder. Sperm samples of 58 males with infer...
