Testicular torsion is a medical emergency with catastrophic sequelae that deserves the same treatment considerations and concerted efforts in research as any other complicated medical condition. The aim of this study was to investigate the effect of Pausinystalia macroceras (PM) bark extract on sperm quality and serum testosterone levels in testicular torsion in a rat model.
Sixty-five (65) mature male Wistar rats apportioned randomly into four experimental groups of A to C; were further divided into four subgroups according to duration of torsion. Group D were the normal regular rats. Each group/subgroup comprised five rats. Testis maintained in the torted position (T) for 1, 2, 3 and 4 hr in Group A (subgroups: AT1+PM, AT2+PM, AT3+PM, and AT4+PM). Group B (sub- groups: B1+PM, B2+PM, B3+PM, B4+PM) were sham-operated animals, which did not undergo torsion and served as the sham control group. Group C subgroups: CT1, CT2, CT3 and CT4 were torted as in A. All animals (except groups C and D) were treated by PM extract (0.1 g/kg b.w. per day) for 56 days. Group D rats were fed distilled water. Serum testosterone concentrations and sperm quality (motility and count) were measured. Analyses of variance with Scheffe's post-hoc test were carried out on the data.
PM extract had a positive effect (significant; p < 0.5) on the sperm count and motility in rats with testicular torsion compared to those not receiving the extract. There was also an increase in serum testosterone levels in the former groups.
Treatment of rats following testicular torsion result to the enhancement of sperm production in comparison with untreated rats.
睾丸扭转是一种具有灾难性后果的医疗急症,与其他任何复杂病症一样,在治疗考量和研究方面都应受到同等重视并投入协同努力。本研究旨在探讨大花帽柱木(Pausinystalia macroceras,PM)树皮提取物对大鼠睾丸扭转模型中精子质量和血清睾酮水平的影响。
65只成年雄性Wistar大鼠随机分为A至C四个实验组;再根据扭转持续时间进一步分为四个亚组。D组为正常常规大鼠。每组/亚组包含五只大鼠。A组(亚组:AT1 + PM、AT2 + PM、AT3 + PM和AT4 + PM)的睾丸在扭转位置(T)分别维持1、2、3和4小时。B组(亚组:B1 + PM、B2 + PM、B3 + PM、B4 + PM)为假手术动物,未经历扭转,作为假对照组。C组亚组:CT1、CT2、CT3和CT4与A组一样进行扭转。所有动物(C组和D组除外)用PM提取物(每天0.1 g/kg体重)治疗56天。D组大鼠喂蒸馏水。测量血清睾酮浓度和精子质量(活力和数量)。对数据进行方差分析并采用谢费尔事后检验。
与未接受提取物的大鼠相比,PM提取物对睾丸扭转大鼠的精子数量和活力有积极影响(显著;p < 0.5)。前一组的血清睾酮水平也有所升高。
与未治疗的大鼠相比,睾丸扭转后的大鼠经治疗可提高精子生成量。
