目的:普通人群年轻男性的睾丸扭转与睾丸功能(精液质量和生殖激素)相关吗?
结论:普通人群年轻男性,与对照组相比,睾丸扭转患者的精液参数没有差异,FSH较高和抑制素B较低的观察结果细微。
背景:睾丸扭转后睾丸功能可能受损,但是知识很少,并且基于小样本量的研究,没有对照组或不太理想的对照组。
方法:进行了一项基于人群的横断面研究,包括7876名生育潜力未知的年轻丹麦男性,从1996年到2020年检查。
方法:所有男性(中位年龄19.0岁)都进行了体检,提供血液和精液样本,并填写了一份问卷,包括关于以前睾丸扭转的信息,出生,生活方式和当前和以前的疾病。睾丸功能标志物,包括睾丸体积,精液参数和生殖激素,对睾丸扭转手术的男性和对照组进行了比较,使用多元线性回归分析。
结果:整个研究期间的平均参与率为24%。总的来说,57名男性(0.72%)以前曾接受过睾丸扭转手术(手术时的中位年龄为13.4岁),其中5名仅剩下一个睾丸。先前有睾丸扭转的男性更容易早产(25%对9.5%的对照组),他们有更高的FSH和更低的抑制素B水平,在粗模型和调整模型中,抑制素B/FSH比低于对照。这种关联主要是由接受单侧睾丸切除术的男性亚组驱动的。没有观察到精液参数的差异。
结论:睾丸扭转的回顾性自我报告信息是一个局限性。此外,由于观察到的差异具有很高的不确定性,因此应谨慎解释结果。
结论:总体而言,我们的研究结果对于经历过睾丸扭转的男性来说是令人放心的,尤其是用睾丸固定术治疗时,对他们来说,生殖激素的改变是微妙的,没有明显的临床相关性。我们的研究发现精液参数没有差异,但需要进行后续研究以评估对生育能力的长期影响.

Is prior testicular torsion associated with testicular function (semen quality and reproductive hormones) in young men from the general population?
In young men from the general population, no differences in semen parameters were observed in those who had experienced testicular torsion compared to controls and observations of higher FSH and lower inhibin B were subtle.
Testicular function may be impaired after testicular torsion, but knowledge is sparse and based on studies with small sample sizes and no control group or a less than ideal control group.
A cross-sectional population-based study was carried out including 7876 young Danish men with unknown fertility potential, examined from 1996 to 2020.
All men (median age 19.0 years) had a physical examination, provided a blood and semen sample, and filled in a questionnaire including information about prior testicular torsion, birth, lifestyle and current and previous diseases. Markers of testicular function, including testis volume, semen parameters and reproductive hormones, were compared between men operated for testicular torsion and controls, using multiple linear regression analyses.
The average participation rate was 24% for the entire study period. In total, 57 men (0.72%) were previously operated for testicular torsion (median age at surgery 13.4 years) of which five had only one remaining testicle. Men with prior testicular torsion were more often born preterm (25% versus 9.5% among controls), and they had significantly higher FSH and lower inhibin B levels, and a lower inhibin B/FSH ratio than controls in crude and adjusted models. The association was mainly driven by the subgroup of men who had undergone unilateral orchiectomy. No differences in semen parameters were observed.
A limitation is the retrospective self-reported information on testicular torsion. Also, results should be interpreted with caution owing to the high uncertainty of the observed differences.
Overall, the results of our study are reassuring for men who have experienced testicular torsion, especially when treated with orchiopexy, for whom reproductive hormone alterations were subtle and without obvious clinical relevance. Our study found no differences in semen parameters, but follow-up studies are needed to assess any long-term consequences for fertility.
