Ethnopharmacological insights: hyperoside from Marsdenia latifolia (Benth.) K.Schum. Mitigates reproductive toxicity in male Wistar rats induced by manganese exposure.

Abstract

This study provides novel findings on the ameliorative effect of hyperoside isolated from Marsdenia latifolia leaves (HIGLL) in reproductive health challenged by manganese toxicity. The study investigated the efficacy of HIGLL on male fertility in rats exposed to manganese chloride (MnCl₂). The rats received either MnCl₂ (30 mg/L) or in combination with HIGLL (100 mg/kg or 200 mg/kg). MnCl₂ reduced fluid intake, organ-body weight, body weight; sperm count, sperm viability, sperm density, sperm motility, semen viscosity, daily sperm production, testicular sperm number; testosterone, follicle-stimulating and luteinising hormones, oestradiol, testosterone/oestradiol ratio; G6PDH, ALP, glucose, NO, acid phosphatase, sialic acid, 17-β-HSD, superoxide dismutase, CAT, GST, GSH, and T-SH without modifying the semen pH and volume, while it correspondingly raised the abnormalities associated with morphology of sperm cells in head, neck, and tail; H₂O₂ and lipid peroxidation levels. HIGLL abrogated the damaged histoarchitecture of the testes and epididymis caused by MnCl₂. HIGLL can serve as a therapeutic agent in the management of male reproductive disorders related to oxidative stress and endocrine disruption.
