Effects of chemotherapeutic agent bendamustine for nonhodgkin lymphoma on spermatogenesis in mice

摘要

Non-Hodgkin lymphoma (NHL)is one of the most common cancers affecting men of reproductive age.The high response rate ofbendamustine as first-line treatment for NHL,coupled with young age of patients,makes elucidation of the impact of treatment on male reproduction important.Our aim was to determine the effects ofbendamustine on male reproduction by animal model.Male mice were treated with bendamustine (40mg/kg)through tail vein injection while cisplatin was given as a standard (3mg/kg)through intraperitoneal injection.After 3 weeks,bendamustine induced weight loss and sperm morphology abnormalities were compared to the control.Additionally,sperm with folded tails were the most frequent abnormality in bendamustine-treated mice.But the mechanism of sperm abnormality induced by bendamustine remains to be elucidated.These results indicate bendamustine may affect spermatozoa of patients who have been treated for NHL.
