Effect of Trihoney (A Mixture of Trigona, Mellifera and Tualang) on Male Reproductive Hormones and Insulin Resistance in Hypercholesterolaemic Rabbits

Abstract

Introduction: Hypercholesterolaemia affects Sertoli and Leydig cells secretory functions, impairs steroidhormone biosynthesis, and disrupts the hypothalamic-pituitary-gonadal axis. The use of honey in previousstudies resulted in an improvement of male reproductive hormonal disturbances. This study aimed toinvestigate the protective effects of Trihoney on hypercholesterolemia-induced male reproductive hormonalchanges in male rabbits and compare its effects with atorvastatin. Materials and methods: Forty-eight maleNew Zealand white rabbits were assigned into 6 groups as follows; Control: commercial pellet; CH:commercial pellet with 0.6 g/kg/day Trihoney; HCD: 1% cholesterol diet; DH1: 1% cholesterol diet with 0.3g/kg/day Trihoney; DH2: 1% cholesterol diet with 0.6 g/kg/day Trihoney and DAt: 1% cholesterol diet with2mg/kg/day atorvastatin. After 12 weeks, the rabbits were sacrificed and blood samples were collected foranalysis of hormones and pro-inflammatory cytokines and calculation of HOMA-IR. The testes werehomogenized for intra-testicular testosterone measurement. Results: Serum testosterone reducedsignificantly in HCD (p<0.05) and DAt (p<0.05) groups. Likewise, intra-testicular testosterone reducedsignificantly in HCD (p<0.01) and DAt (p<0.01) groups. Serum FSH increased significantly in HCD (p<0.001)and DAt (p<0.01). Trihoney particularly at the dose of 0.6 g/kg/day improved serum and intra-testiculartestosterone (p<0.05) and FSH (p<0.05). Trihoney and atorvastatin improved serum pro-inflammatorycytokines. Trihoney and atorvastatin did not affect HOMA-IR. Conclusion: Trihoney attenuated thedetrimental effects of hypercholesterolaemia on male reproductive hormones which probably through alocal effect on testicular tissue and Trihoney anti-inflammatory effect independent of insulin resistance.Atorvastatin did not counteract the impact of hypercholesterolaemia on the reproductive hormones.

Nigella sativa-Floral Honey and Multi-Floral Honey versus Nigella sativa Oil against Testicular Degeneration Rat Model: The Possible Protective Mechanisms

“…Chrysin (the main bioactive component of honey) acts as a testosterone-boosting agent and subsequently exhibits testosterone production [ 82 ]. Likewise, an antioxidant compound in honey, which is pantothenic acid, regulates the hormone for adrenal steroid secretion [ 83 ] and then works through hypothalamic hormone secretion to regulate the neuroendocrine–gonadal axis [ 84 ]. Furthermore, the antioxidant activity of honey may control anti-apoptotic patterns in testicular tissue [ 50 ].…”
