Background: This investigation was aimed to evaluate the effect of Speman®, a well known ayurvedic proprietary preparation, in an experimental model of cyclophosphamide-(CP) induced oligospermia in rats.
Materials and Methods: Thirty male rats were randomized in to five, equally-sized groups. Rats in group 1 served as a normal control; group 2 served as an untreated positive control; groups 3, 4, 5 received Speman® granules at doses of 300, 600, and 900mg/kg body weight p.o. respectively, once daily for 13 days. On day four, one hour after the respective treatment, oligospermia was induced by administering a single dose of CP (100mg/kg body weight p.o.) to all the groups except group1. At the end of the study period the rats were euthanised and accessory reproductive organs were weighed and subjected to histopathological examination. The semen samples were subject to enumeration of sperms. Weight of the reproductive organs, histopathological examination of the tissues, and sperm count were the parameters studied to understand the effect of Speman® on rats with CP-induced oligospermia.
Results: Changes that occurred due to the administration of CP at a dose of 100 mg/kg body weight were dose dependently reversed with Speman® at a dose of 300, 600, and 900 mg/kg body weight. There was a statistically significant increase in sperm count and the weight of the seminal vesicle, epididymis, and prostate.
Conclusion: Findings of this investigation indicate that Speman® dose dependently reversed the CP-induced derangement of various parameters pertaining to the reproductive system. This could explain the total beneficial actions of Speman® reported in several other clinical trials.
