ABSTRACT
Lead toxicity is a common industrial hazard. It affects all systems of the body. The study was conducted to see reduction in volume of the testes of albino rats and reversal of it with high dosages of vitamin C. Experimental study. The study was conducted in the Department of Anatomy, Post Graduate Medical Institute [PGMI], Lahore from May 2007 to April 2009. 90 albino rats were divided into five groups A, B, C, D and E. Each group was comprised of 18 animals and divided into 3 subgroups 1, 2 and 3 sacrificed after 5[th], 6[th] and 7[th] weeks. Groups A was given normal saline, group B was given lead acetate 10 mg/kg body weight, group C was given lead acetate with 250 mg/kg body weight of vitamin C, group D was given lead acetate with vitamin C 500 mg/kg body weight and group E was given vitamin C 1000 mg/kg body weight with lead acetate intraperitoneally. The animals sacrificed after the 5[th] week in subgroups A1, B1, C1, D1 and E1 showed insignificant changes while in subgroup A2, B2, C2, D2 and E2 sacrificed after 6[th] week, P value was 0.015 which was significant. The P value of subgroup 3 sacrificed after 7[th] week was 0.002 which was significant. This study showed that lead toxicity brought caused a significant reduction in the volume of the testes. The testes regained their normal size after heavy dosage of vitamin C
