Purpose: To study the influence of prepubertal unilateral testicular torsion on spermatogenesis postpubertally.
Methods: Sixty prepubertal SD male rats were divided into 6 groups. In each group, animal suffered different courses of unilateral testicular torsion including sham operation, 2- and 6-hour-long torsion, and permanent torsion. Salvia miltiorrhiza was injected as a remedy to release the I/R injury in the 2- and 6-hour-long torted groups. Postpubertally, the percentage of DNA content of haploid cells in the testes was determined individually.
Results: The percentage of haploid cells in the sham operation group was 76.5+/-1.9%. The number decreased in every other group (p<0.01). Comparing with the same course of torsion, Salvia miltiorrhiza injection could improve the percentage of haploid cells (p<0.01). In the permanent unilateral testicular torted group, the percentage was nearly zero (0.4+/-0.2%).
Conclusions: Prepubertal unilateral testicular torsion induces decreased spermatogenesis postpubertally. The result takes place in the bilateral testes. Salvia miltiorrhiza, as an antioxidant remedy, could relieve the injury which manifests improved spermatogenesis.

Objectives: Testicular torsion, a condition requiring urgent intervention, can occur at any age and present with diverse symptoms. To the best of our knowledge, no study has evaluated the characteristics of testicular torsion in childhood, a less common age group. This study showed differences in patients' characteristics between childhood and adolescence and the variation across ages.

Background: Fetal midgut volvulus is a rare disease, with a high risk of potentially life-threatening fetal complications.
Purpose: The aim of this study was to retrospectively analyze the imaging findings of fetal midgut volvulus diagnosed by magnetic resonance imaging (MRI) and explore its value in non-invasive prenatal diagnosis.
Methods: A retrospective collection of data from 156 fetuses suspected of intestinal obstruction by ultrasound examination in our hospital was conducted.

Multiple conditions can cause hypoxia in the testis, including exposure to high altitude, sleep apnoea, testicular torsion and varicocele. Varicocele accounts for up to 44% of instances of primary infertility, but the cumulative contribution of hypoxic conditions to male infertility is undefined. Results of controlled hypobaric hypoxia studies have demonstrated a substantial detrimental effect of short-term and long-term exposures on sperm; however, downstream effects on embryo development and offspring health are less well understood.

Background: Testicular torsion-detorsion damage is a common ischemia-reperfusion injury brought on by an excess of reactive oxygen species. Reactive oxygen species may affect cellular differentiation by regulating gene expression. The gene expression in the testis is essential for spermatogenesis.
