Spermatogenesis, gonadal sperm reserves and fertility of rabbits fed micro doses of fumonisin

The effects of micro doses dietary fumonisin, a metabolite Fusarium verticillioides, on spermatogenesis, gonadal sperm reserves and fertility rabbits were studied. Relative paired testis weight; production rate storage potential not adversely affected in which exposed to varied minute levels fumonisin about 153-161 µg/kg body weight/day over period 8 weeks. toxin also failed exert any influence (P>0.05) seminiferous tubular diameter volume percent testicular elements. Male as evidenced by conception rate, litter size embryo survival normalcy was (P>0.05). However, the frequency occurrence stages II VIII cycle epithelium significantly (P<0.05) influenced with increased levels. results suggest that ingestion Fusarium-infected feed would result liberation 153 µg fumonisin/kg weight per day for short time may male or resulting foetuses.
