“…The clinical usage of CP is restricted due to its severe dose‐dependent side effects (Bayindir et al, ; Eid, Abdelkader, Abd El‐Raouf, Fawzy, & El‐Denshary, ). Previous research showed that CP treatment caused damage to many tissues and organ systems, such as reproductive toxicity (Kaya et al, ), nephrotoxicity (Masuda, Inoue, Miyata, Mizuno, & Nanba, ), hepatotoxicity (Ciftci, Onat, & Cetin, ), ototoxicity (Bayindir et al, ), ocular toxicity (Taşlı et al, ) and neurotoxicity (Kaya, Ciftci, Cetin, Tecellioğlu, & Başak, ). Many previous studies on CP‐induced male reproductive system toxicity demonstrated that CP administration led to oxidative damage and apoptosis in testicular tissue, a decline in testes' weight, an increase in abnormal sperm rate and a decrease in sperm concentrations and motility (Aksu et al, ; Ciftci et al, ; Kaya et al, ; Saral et al, ).…”
