Rosemary (Rosmarinus officinalis L. - Lamiaceae) is a shrub used in the treatment of hepatic, intestinal, renal and respiratory affections. Its toxicity was assessed in female rats and an anti-implantation effect was reported after treatment with this plant. This work analyzes the effect of the short-term administration of R. officinalis extract on vital organs, on the organs of the reproductive system and sperm production of mature male Wistar rats. Adult Wistar rats were treated with 1 mL of R. officinalis aqueous extract at a dose level of 291.2 mg and 582.4 mg/kg of body weight for five days. Body and organs weights, sperm production and food consumption were evaluated. The results showed that the lower dose administration of R. officinalis extract did not significantly alter body and organs weight nor did it interfere with gamete production. However, animals treated with the higher dose showed significant weight increase of the seminal vesicle but no significant alteration of the other variables. Food intake was not affected by the treatments.
