Abstract

Background: Cannabis addiction poses risks to male fertility by lowering levels of glial cell line-derived neurotrophic factor (GDNF), which is vital for spermatogenesis.

Objective: This research aimed to determine if the injection of exogenous GDNF into the brain of cannabis-addicted rats has a positive impact on their behavior and spermatogenesis.

Materials and methods: This study involved 15 male Wistar rats divided into 3 equal groups: control, model, and experimental. Cannabis addiction was induced in the model and experimental groups using a smoking machine with a 0.25 gr dose per 5 rats, and the experimental group received a 0.5 mg GDNF treatment via stereotaxic injection. Behavioral changes were assessed through plus maze, open field, and sucrose preference tests before and after treatments. Sperm parameters were evaluated with H&E staining, sperm morphology with Diff-Quik staining, DNA damage and viability with acridine orange and trypan blue staining.

Results: Addicted rats displayed increased anxiety, which was improved by GDNF treatment (p < 0.05). Although cannabis significantly reduced germ cells and the size of the testis and epididymis compared to controls (p = 0.0006, p = 0.003), GDNF had a limited effect on these aspects. Cannabis significantly altered sperm morphology (p = 0.0016), but GDNF reversed abnormal sperms. GDNF improves sperm quality, reverses cannabis-induced sperm grading alterations (grade C, p = 0.0295), reduces DNA damage significantly (p = 0.0242), and enhances sperm viability, highlighting its potential to counteract some of cannabis's harmful effects on male reproductive health.

Conclusion: The findings of this experiment suggest that exogenous GDNF could be a potential therapeutic agent for cannabis addiction and sperm parameters.

神经营养因子治疗大麻成瘾大鼠神经胶质细胞系来源的成瘾行为和精子发生的评估:一项实验研究。
背景:大麻成瘾通过降低神经胶质细胞系来源的神经营养因子(GDNF)水平对男性生育能力构成风险,GDNF对精子发生至关重要。目的:研究在大麻成瘾大鼠脑内注射外源性GDNF是否对其行为和精子发生产生积极影响。材料与方法:雄性Wistar大鼠15只,随机分为对照组、模型组和实验组。模型组和实验组采用吸烟机诱导大麻成瘾,每5只大鼠0.25 g剂量,实验组采用立体定向注射方式给予0.5 mg GDNF治疗。在治疗前后通过迷宫、空地和蔗糖偏好测试来评估行为变化。用H&E染色评价精子参数,用diff - quick染色评价精子形态,用吖啶橙和台盼蓝染色评价DNA损伤和活力。结果:成瘾大鼠焦虑增加,经GDNF治疗后明显改善(p < 0.05)。虽然与对照组相比,大麻显著减少了生殖细胞和睾丸和附睾的大小(p = 0.0006, p = 0.003),但GDNF对这些方面的影响有限。大麻显著改变了精子形态(p = 0.0016),但GDNF逆转了异常精子。GDNF可改善精子质量,逆转大麻引起的精子等级改变(C级,p = 0.0295),显著减少DNA损伤(p = 0.0242),并提高精子活力,突出其抵消大麻对男性生殖健康的某些有害影响的潜力。结论:本实验结果提示外源性GDNF可能是治疗大麻成瘾和精子参数的潜在药物。
