Abstract Chemotherapy and radiotherapy adversely affect spermatogenesis, a consequence that is particularly relevant to young men who have yet to establish families. The harmful effects of chemotherapy on spermatogenesis are variable, depending on the type and dosage of chemotherapeutic agents used. The current study assessed the effect of cancer therapy on sperm DNA fragmentation by Comet assay. Sperm DNA fragmentation was evaluated in cured cancer patients. The results showed a significant relationship between chemotherapy and double-stranded and single-stranded sperm DNA fragmentation.
 
 

Abstract Spermatogenesis is a very complex process that can be affected by a number of factors which may lead to reduced fertility or infertility. Busulfan kills spermatogonia stem cells and disrupts the connections between Sertoli and spermatogonia cells at base layers. Moreover, vitamin D is very important in the reproductive system of men. In this study, the effect of vitamin D on biosulfur-induced azoospermia in mice was investigated. The results showed an increase in the quality of sperm parameters in the group treated with vitamin D.
