Abstract

Antimetabolite, 5-fluorouracil (5-FU) is known to cause testicular damage by epithelial sloughing and cell killing. However, it is not known whether 5-FU induces tubular atrophy and the fate of exfoliated germ cells. Present study was conducted to evaluate these effects of 5-FU on rat testis. Animals were injected, single dose of 5-FU (10.50 & 100 mg/kg, i.p.) and sampled at 1, 3, 15 and 30 day following the treatment. The testes were perfusion fixed by Bouin's fluid. Five micron thick paraffin sections of testes and epididymis were stained with haematoxylin and eosin. Slides were examined for the incidence of abnormal tubules (per 200 tubules), tubular diameter (STD), epithelial height (SEH) and for the presence of germ cells in the epididymes. Data were analysed by Mann-Whitney 'U' test. The testes weight, STD, SEH were decreased (P<0.05-0.01) in treated animals. The abnormal tubules were increased in a dose dependent manner with atrophic tubules seen on 30 d. The exfoliated germ cells have not blocked the post testicular ductal system and found in the epididymis in a dose dependent manner. The present study concludes that 5-FU causes tubular shrinkage and atrophy. Further, epididymis is involved in the phagocytosis of germ cells.
