the effect of tarantula cubensis (theranekron) on some reproductive parameters in male rats

Background: tarantula cubensis (theranekron), obtained from the poison of cuban tarantula, is a homeopathic drug frequently used in animal health. objectives: the effect of theranekron on reproductive parameters in male animals is unknown. in this study, the effect of theranekron on male reproductive parameters was investigated. methods: three different groups of rats were created: control (n=8) (no application), theranekron i (n=8) (subcuteneous injection of 0.3 mg/kg on days 0, 5, and 10), and theranekron ii (n=8) (subcuteneous injection of 0.3 mg/kg on days 0, 5, and 10). control and theranekron i groups were sacrificed at the end of the 4 weeks, and the theranekron ii group was sacrificed at the end of the 6 weeks. sperm motility, density, abnormal rate, dna damage, and testicular histopathology were examined. results: no statistical difference was observed in the parameters examined between the study groups (p>0.05). it was determined that the theranekron did not change sperm motility, density and spermatozoa ratio, also no histopathological changes, and sperm dna damage.conclusion: there is no harm in using theranekron in male animals during the breeding and nonbreeding seasons.
