This study investigated the protective effect of bromelain on sperm quality and DNA, antioxidant system and testis structure in rats with experimentally induced nickel toxicity. Four groups, each of 10 male Wistar albino rats, were established. One was maintained for control purposes, while the other three received bromelain alone, nickel alone and nickel+bromelain. While bromelain was administered by oral route (20 mg/kg), nickel sulfate was given intraperitoneally (20 mg/kg) at alternate days. Nickel exposure significantly reduced relative testicular weight and seminiferous tubule diameter. Nickel exposure also led to significantly decreased antioxidant levels, as well as a negative impact on sperm quality. On the other hand, nickel+bromelain administration increased sperm motility, sperm counts, viable sperm percentage and antioxidant levels, and reduced sperm DNA fragmentation. It was concluded that the administration of bromelain which has antioxidant effect to nickel-intoxicated rats prevented damage to sperm quality and DNA, and the antioxidant system.

This study was aimed at investigating the use of intra-testicular calcium chloride (CaCl₂) and 4-vinylcyclohexene 1,2-monoepoxide (VCM) injections as a side effect-free alternative method for the control of reproduction in guinea pigs. Fifty male guinea pigs were randomly assigned to five groups. In all groups, the chemical agents were injected into both testes in 1% lidocaine hydrochloride. While Groups I, II and III were administered with a single dose (0.25 mL) of sterile physiological saline, 15 mg/100 g CaCl₂, and 240 mg/kg VCM, respectively, Group IV and V received a daily dose of 15 mg/100 g CaCl₂, and 240 mg/kg VCM for 3 days, respectively. On day 90 post-administration, all animals were weighed and later decapitated under ether anaesthesia. Blood and tissue (testis, liver, hypophysis and adrenal gland) samples were taken. Sperm samples from the cauda epididymis were examined for spermatological parameters. Blood was used for hormone analyses and tissue samples were examined histopathologically (haematoxylin-eosin) and immunohistochemically (Tunel staining). The epididymal sperm count decreased in all treatment groups. Excluding 2 animals, Group V displayed azoospermia. When compared to the control group, Group V displayed the highest prolactin and lowest testosterone levels, and Group III showed the highest testosterone level. Histopathological examination revealed no intoxication finding. Chemical castration with VCM may be a good alternative to surgical castration as it enables mass sterilization without postoperative risks in guinea pig.
