ABSTRACT=<p>The high rate of male infertility and the meager resources to manage same in sub Saharan Africa have necessitated the search for cost effective and available alternatives. Mushrooms have been used traditionally in folk medicine and as nutraceuticals. This study has investigated the effect of the wild mushroom <italic>Pleurotus tuber-regium</italic> on carbon tetrachloride (CCl<sub>4</sub>) deleterious effects on the reproductive system of male rats. Thirty six rats were divided into six groups of six animals each. Group I (negative control) received 10 ml/kg olive oil intraperitoneal weekly in addition to feed and water <italic>ad libitum</italic>. Group II (positive control) received CCl<sub>4</sub> 10 ml/kg (30% in Olive oil) weekly. Group III, IV, and V received 100 mg, 20 0mg, and 500 mg <italic>P. tuber-regium</italic> (33.3% in feed) daily in addition to 10 ml/kg CCl<sub>4</sub> weekly. Group VI received 500 mg <italic>P. tuber-regium</italic> (33.3% in feed) daily. After 4 weeks, sperm motility, epididymal count and vitality were determined. Serum malondialdehyde (MDA), testosterone, Luteinizing hormone (LH), Follicle stimulating hormone (FSH), prolactin and oestradiol were estimated using enzyme-linked immunosorbent assay (ELISA) kits. Histopathologic examinations of the testis were carried out. Carbon tetrachloride significantly reduced the sperm motility (54.33 ± 3.79%), epididymal count (28.73 ± 2.86 × 10<sup>6</sup>/ml, vitality (4.96 ± 0.62), LH (0.88 ± 0.14), FSH (2.04 ± 0.33), and Testosterone (2.02 ± 0.24) when compared with control (89.33 ± 9.01), 91.91 ± 1.92 × 10<sup>6</sup>/ml, 13.12 ± 0.19, 2.74 ± 0.32, 3.64 ± 0.62, and 4.16 ± 0.23, respectively, which were reversed by <italic>P. tuber-regium</italic> administration. Co-administration of <italic>P. tuber-regium</italic> plus CCl<sub>4</sub> significantly reduced MDA level. <italic>P. tuber-regium</italic> showed dose dependent ameliorative activity against CCl<sub>4</sub> deleterious action on the testis and may be beneficial in the management of male infertility.</p>
