Effects of vancomycin linoleic acid nanoparticles on male reproductive indices of Sprague–Dawley rats

Abstract

The management of bacterial infections, especially trains of methicillin-resistant Staphylococcus aureus observe in health care settings, has markedly improved with the introduction of established drugs but using newer nano-based formulations. This study investigates the effects of vancomycin-linoleic acid nanoparticles on testicular tissue in an experimental animal model. Twenty-five adult male Sprague–Dawley rats maintained at the Animal House of the Biomedical Resources Unit were assigned to five groups namely E – solid lipid nanoparticles; F – vancomycin solid lipid nanoparticle; G – linoleic acid nanoparticle; H – vancomycin linoleic acid; and A – control. Perturbations in seminal fluid parameters showed a reduced sperm count in groups F & G which was statistically significant (p .05). There was also increased luteinizing hormone (LH) and decreased in follicular stimulating hormone (FSH) levels was statistically significant (p < .05). Hypoplasia, tubular atrophy and shrinkage were observed in histologic sections of the treated groups with basement membrane thickening. Vancomycin solid lipid nanoparticle and its constituents SLN and LA disrupted testicular morphometry and the hormonal milieu sufficient to potentially induce altered reproductive function.
