Abstract
Aims Heme oxygenase (HO-1) affords protection against ischaemia/reperfusion (I/R) injury; however, its effects on testicular I/R injury remain poorly explored. Herein, we aimed to examine the effects of HO-1 on testicular I/R injury and elucidate the underlying mechanism. Methods Using the TALEN technique, we knocked out the HO-1 gene from rats. In vivo: Thirty hmox+/+ and 30 hmox-/- rats were randomly assigned to six groups: sham-operated (sham), I/R (the left testicle torsion/detorsion) 0 d,I/R 1d, I/R 3d, I/R 7d and I/R 28d. In vitro: GC-1 were suffered from: control,H/R (oxygen-deprivation/reoxygenation),H/R + HO-1 siRNA,H/R + c-Jun siRNA or H/R + HO-1 siRNA + c-jun.We performed immunofluorescence and immunohistochemistry experiments to detect HO-1 nuclear translocation. Flow cytometry was used to detect cell apoptosis and analyse the cell cycle. High-resolution miRNA, mRNA sequencing, reverse transcription-quantitative PCR, and western blotting were performed to identify testicular I/R injury-related genes strongly conserved in HO-1 knockout rats. A double luciferase reporter assay was performed to verify the relationship between C-jun and miR-221/222. Main findings In vivo, HO-1 improved the pathological damage induced by testicular I/R. In GC-1 cells, we confirmed the nuclear translocation of HO-1 and its protective effect against hypoxia/reoxygenation (H/R) damage. Accordingly, HO-1 protein itself, rather than heme metabolites, might play a key role in testicular I/R. Gene sequencing was performed to screen for miR221/222 and its downstream gene, thymocyte selection-associated high mobility group box (TOX). HO-1 increased c-Jun phosphorylation in the H/R group, knocked down c-Jun in GC-1 cells, and decreased miR-221/222 expression. Inhibition of HO-1 expression decreased the expression of c-Jun and miR-221/222, which was rescued by adding c-Jun. Dual-luciferase reporter assay confirmed the interaction between c-Jun and miR-221/222. Conclusions HO-1 could exert a protective effect against testicular I/R via the phosphorylated c-Jun-miR-221/222-TOX pathway.

Abstract
Testicular torsion (TT) is a medical emergency that requires immediate diagnostic evaluation. Photoacoustic imaging (PAI) has the potential to provide spatially resolved oxygen saturation (sO2), which can serve as a valuable marker in TT diagnosis. We investigated the potential of PAI as an alternative method for TT diagnosis and testicular injury assessment. We measured sO2 levels in different degrees of TT models using PAI at various time points. Based on histopathological results, we found that the averaged sO2 per pixel (sO2®) and reduction of sO2® (rsO2) in twisted testicles had significant correlations with hypoxic conditions. Both sO2® and rsO2 exhibited excellent diagnostic abilities in detecting TT and identifying ischemia/hypoxia injury following TT. Furthermore, PAI-measured sO2 demonstrated favorable diagnostic capabilities in discriminating if the testicle had suffered irreversible injury. In summary, PAI presents a potentially promising novel approach in evaluating TT and warrants further clinical investigation.

Abstract
OBJECTIVE To evaluate the impact of insulin like growth factor-1(IGF-1) and growth hormone (GH) on testis histology, spermatogenesis, and fertility in prepubertal rats exposed to 6 h of testicular torsion (TT) and detorsion. MATERIAL-METHOD Forty-eight male Wistar-albino rats weighing 30-70g and at 3-week age were allocated into six groups involving eight rats in each group as follows: Group 1:Sham, Group 2:Control, Group 3:Gelatin, Group 4:Local-IGF-1, 5: Local-GH, Group 6: Systemic-GH. Right testis was only exposed and sutured in the sham group, and right testes were rotated clockwise, 720°, fixed, and 6 h later, detorsion on the testis was done in groups 2-6. Unloaded gelatin, 5 μg local-IGF-1 loaded, and 2IU rhGH loaded gelatin were sutured to the right testis after detorsion in groups 3-5. In Group 6, 0.3IU/100gr/d rhGH was given for seven days via subcuticular route after detorsion. Each of the rats cohabited with two female rats five weeks later. Afterward, both right and left testes were removed. Mean diameter of seminiferous tubules (STD), mean biopsy score count of the testis (TBSC), mean percentage of haploid cells (HCP) were assessed, and fertility parameters were evaluated. RESULTS STD and TBSC of the ipsilateral testes were significantly reduced in control and gelatin groups when compared to sham, local-IGF-1, and local-GH groups. STD and TBSC of the ipsilateral testes of the systemic-GH group were decreased compared to the sham group. HCP of the ipsilateral testes of control, gelatin, and systemic-GH groups were significantly lower than the sham, local-IGF-1, and local-GH groups. STD, TBSC, and HCP of the contralateral testes were significantly reduced in control and gelatin groups when compared separately to sham, local-IGF-1, systemic- GH, and local-GH groups. The difference between groups regarding potency, fertility, fecundity indexes, and mean fetus numbers were not significant. CONCLUSION Even though there was significant and permanent histologic germ cell damage and reduced HCP in both ipsilateral and contralateral testes, experimental 6 h TT and detorsion in prepubertal rats did not have a negative impact on future fertility. Local-IGF-1and rhGH treatment improved germ cell histology and spermatogenesis in both ipsilateral and contralateral testes of prepubertal rats, subjected to 6 h of TT and detorsion.

Abstract
Testicular torsion is a serious emergency and a well-known cause of male infertility. It represents 10 %-15 % of scrotal diseases in children. Kisspeptin (KISS1) is a hormone secreted from the hypothalamic nuclei and testis, but its role in testis is not fully understood. Semaglutide is a novel antidiabetic glucagon-like peptide 1 (GLP-1) analog. Hence, we designed the current study to elucidate the possible ameliorative effect of semaglutide on ischemia/reperfusion-induced testicular dysfunction in rats and highlight the role of the testicular GLP-1/PCG-1α-PPAR-α-KISS1 signaling pathway. We randomly divided 50 male Sprague Dawley into five equal groups (10 rats each): SHAM, exendin 9-39 -treated (EX), testicular torsion/detorsion (T/D), testicular torsion/detorsion and semaglutide-treated (SEM + T/D), and testicular torsion/detorsion, exendin, and semaglutide-treated (EX + SEM + T/D). We quantified serum follicle-stimulating hormone, luteinizing hormone, total testosterone, testicular oxidative stress markers, testicular gene expression of GLP-1/KISS1 pathway-related genes (KISS1, KISS1R, GLP-1, GLP-1R, PGC-1α, PPAR-α), steroidogenesis pathway-related genes (STAR, CYP11A1, CYP17A1, HSD17B3, CYP19A1), HO-1, Nrf-2, and testicular protein expression of HIF-1α, TNF-α, NF-κβ, Caspase-3, FAS, proliferating cell nuclear antigen, and KISS1 through testicular histopathology and immunohistochemistry assays. Testicular torsion/detorsion markedly elevated proapoptotic, proinflammatory, and oxidative stress marker levels, noticeably downregulating the expression of GLP-1/KISS1 and steroidogenesis pathway-related proteins. Semaglutide administration significantly ameliorated all these deleterious effects. Nevertheless, injecting exendin, a GLP1-R antagonist, before semaglutide abolished all the documented improvements. We concluded that semaglutide ameliorated ischemia/reperfusion-induced testicular dysfunction by modulating the GLP-1/PGC-1α-PPAR-α/KISS1/steroidogenesis signaling pathway, improving testicular oxidative state, and suppressing testicular inflammation and apoptosis.
