Fenugreek seed exhibits antidiabetic, antineoplastic, hepatoprotective, antidepressant and immunomodulatory properties. Fenugreek also causes antifertility effects in rodents. However, the impact of fenugreek seed on male reproduction and the possible mode of its action are not properly evaluated. Herein, we examined the effect of aqueous seed extract of fenugreek (FSE) and the possible mechanism of its action on male reproductive health in mice. Parkes mice were orally administered FSE (600 mg/kg body weight/day) or distilled water for 28 and 56 days, respectively. Various sperm parameters, histopathology, serum testosterone level and fertility indices were assessed. Furthermore, steroidogenic enzymes activities, oxidative status and germ cell dynamics in the testis were evaluated. Toxicological endpoints were also assessed. Treatment with FSE caused degenerative changes in the testis histoarchitecture. The treatment also affected various sperm parameters and concentrations of sialic acid and fructose in the epididymis and seminal vesicle, respectively. Fenugreek treatment also had negative impact on oxidative status and germ cell dynamics in the testis; fertility indices were also affected in female mice impregnated by the extract-treated male mice, though libido of the treated male mice remained unaffected. Results show that treatment with FSE caused adverse effects on the male reproductive health and pregnancy outcome in Parkes mice.
