Morphine and Phoenix dactylifera (dates) effects on the histological features of male rat reproductive organs.

Abstract

Background:Previous studies have shown that morphine negatively effects male fertility while Phoenix dactylifera (dates) could cure male infertility by the exhibition of antagonist effects. This study was conducted to assess the possible ameliorating effects of dates on the histological features of morphine-induced male rat reproductive organs.Materials and Methods:Adult male Sprague Dawley rats age 7–9 weeks old, 200–250 g body weight (BW) were divided into six rats per each group: Group 1, force-fed with distilled water, 1 ml/kg BW for 35 days (control); Group 2, intramuscularly (IM) injected with morphine, 20 mg/kg BW for 7 days followed by force-fed with distilled water for 28 days; Group 3, force-fed with distilled water for 7 days followed by crude P. dactylifera extract, 200 mg/kg for 28 days; Group 4, injected (IM) with morphine, 20 mg/kg BW for 7 days followed by force-fed of crude P. dactylifera extract, 200 mg/kg for 28 days. Rats were sacrificed on day 36. The seminal vesicle (SV) and prostate gland (PG) were removed and fixed before histological processes.Results:In morphine-treated rats, the SV showed the absence of honeycomb-like appearance with flattened columnar cells while in the PG, eosinophilic secretion was noted to be absent from glandular lumina as compared to the control group. Administration of P. dactylifera extract in Group 4 showed improvement in histoarchitecture of the SV and PG with complex mucosal infoldings and glands luminal filled with secretion.Conclusion:P. dactylifera extract has a protective effect against the adverse effects of morphine on the male rat reproductive organs.
