Objective: Frequently, reproductive toxic substances such as androgenic anabolic steroids, alcohol and nicotine are used in association by adolescents and adults, in an indiscriminate manner. This study investigated the testicular and epididymal tissue of adult rats submitted to a recovery period after treatment with anabolic steroid, alcohol and /or nicotine. Materials and Methods: The animals (n=42) were divided into three control groups simulating the drugs administration routes (CI: distilled water, oral; CII: saline solution, subcutaneous; CIII: water and saline solution) and groups treated with a testosterone esters mixture (T: 7.5 mg/kg body weight - b.w., subcutaneous), alcohol (AL: 3.5 g/kg b.w. of ethanol 25%, oral), nicotine (N: 2.0 mg/kg b.w., subcutaneous), and co-administration of these three substances (T/AL/N). After 15 consecutive days of treatment (once a day), the animals were kept for 30 days in recovery. At the end of this period, the testes and epididymides were collected, weighed and processed for histological and morphometric analysis by light microscope. Results: All groups treated with toxic substances presented histopathological changes in testes and epididymis after the recovery period. There was a significant decrease (p
