Background:
Spermatogenesis is a highly conserved and regulated process and it is sensitive to fluctuations in the physical and chemical environment. Gemcitabine is a novel antimetabolic anticancer drug used frequently in the treatment of many cancers. This study aimed to investigate the histomorphometric effects of gemcitabine on spermatogenesis in Swiss albino mice.
Materials And Methods:
Gemcitabine in high and low doses (80 and 40 mg/kg) injected intraperitoneally to inbred Swiss albino mice. Gross testicular features and seminiferous tubular histomorphometry was studies at the end of 7(th), 14(th) day and at 2 months sperm shape abnormalities were studied.
Results:
Seminiferous tubular morphology was altered significantly, showing a reduction in height, perimeter and area in a dose dependent manner. Sertoli cell number decreased. Basement membrane thickness was reduced and it appeared to be permanent, with statistically insignificant changes even after 2 months. There was a reduction of intertubular spaces. Sperms have shown banana heading, decapitation and loss of normal hook of head. The effects were partially reversible at the end of 2 months.
Conclusion:
It was concluded that gemcitabine affects the process of spermatogenesis adversely in a dose and time dependent manner and the effects are partially reversible.
