Abstract
Testicular torsion is a urological emergency that involves the twisting of the spermatic cord along its course. Compelling pieces of evidence have implicated oxidative stress-sensitive signaling in pathogenesis of testicular I/R injury. Although, surgical detorsion is the mainstay management; blockade of the pathways involved in the pathogenesis may improve the surgical outcome. Experimental studies using various testicular I/R models have been reported in a bid to explore the mechanisms associated with testicular I/R and evaluate the benefits of potential therapeutic measures; however, most are limited by their shortcomings. Thus, this review was intended to describe the details of the available testicular I/R models as well as their merits and drawbacks, the pathophysiological basis and consequences of testicular I/R, and the pharmacological agents that have being proposed to confer testicular benefits against testicular I/R. This provides an understanding of the pathophysiological events and available models used in studying testicular I/R. In addition, this research provides evidence-based molecules with therapeutic potentials as well as their mechanisms of action in testicular I/R.

[PMID: 36825607 DOI: 10.1111/andr.13418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 02/13/2023] [Accepted: 02/20/2023] [Indexed: 02/25/2023]
Abstract
BACKGROUND Testicular torsion is a condition in which a testis rotates around its longitudinal axis and twists the spermatic cord. This in turn results in a significant decrease in blood flow and perfusion of testicular tissue. During Testicular torsion, the testicular tissue is affected by ischemia, heat stress, hypoxia, and oxidative and nitrosative stress. The testicular torsion should be considered an emergency condition and surgical intervention (testicular detorsion ) as the sole treatment option in viable cases involves counter-rotation on twisted testes associated, when possible, to orchipexy, in order to avoid recurrence. Possible testicular detorsion side-effects occur due to reperfusion and endothelial cells injury, microcirculation disturbances, and intense germ cells loss. OBJECTIVES To discuss testicular torsion surgery-based methods, different time frames for testicular torsion induction, and the associated pathophysiology by emphasizing cellular and molecular events as well as different therapeutic agent applications for testicular torsion. MATERIALS AND METHODS We reviewed all original research and epidemiological papers related to testicular torsion condition. RESULTS Testicular torsion causes germ cell necrosis, arrested spermatogenesis, and diminished testosterone levels, with consequent infertility. Among different involved pathophysiological impacts, testicular torsion/detorsion-induced ischemia seems to play the key role by leading the tissue toward other series of events in testis. Numerous studies have used adjuvant antioxidants, calcium channel blockers, anti-inflammatory agents, or vasodilating agents in order to decrease these effects. DISCUSSION AND CONCLUSION To the best of our knowledge, no previously conducted study examined therapeutical agents' beneficial effects post clinical I/R condition in humans. Different agents targeting different pathophysiological conditions were used to ameliorate the ischemia/reperfusion-induced condition in animal models, however, none of the administrated agents were tested in human cases. Although considering testicular detorsion surgery is still the golden method to reverse the testicular torsion condition and the surgical approach is undeniable, the evaluated agents with beneficial effects, need to be investigated furthermore in clinical conditions. Thus, furthermore clinical studies and case reports are required to approve the animal models proposed agents' beneficial impacts.

Int Immunopharmacol 2021; 101:108197. [PMID: 34626874 DOI: 10.1016/j.intimp.2021.108197] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 09/12/2021] [Accepted: 09/23/2021] [Indexed: 11/26/2022]
Abstract
Twisting of the spermatic cord is a common dangerous health problem that may be accompanied with testicular necrosis and infertility. Cilostazol (CLZ) is a selective phosphodiesterase (PDE) 3A inhibitor used for treatment of intermittent claudication. It has a great role in myocardial, spinal cord and hepatic ischaemia/reperfusion. However, till now, there are no researches evaluating its role in testicular ischaemia/reperfusion (TIR). The current work studies its capability to improve TIR induced injury with more concentration on the mechanisms involved in such effect. Four groups of animals were included: sham, TIR induced group, TIR plus CLZ low dose (10 mg/kg), TIR plus CLZ high dose (30 mg/kg). Our results proved that TIR had significant decrease of the serum ELISA of testosterone, marked disturbances in oxidative stress evaluated parameters as malondialdehyde (MDA), reduced glutathione (GSH), total antioxidant capacity (TAC), ELISA measurement of tumor necrosis factor alpha (TNFα) and interleukin 1 beta (IL1β) inflammatory mediators, apoptotic marker (caspase3) using western blotting, immunohistochemistry of hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF). TIR reduced the protective agents as cyclic adenosine monophosphate (cAMP) and sirtuin-1 (SIRT1) by ELISA method with marked germinal cell apoptosis. The biochemical results were confirmed by the histopathological findings that showed marked decrease in both Johnsen's score and Cosentino's score. However, treatment with CLZ significantly reversed the profound TIR damaging effects, on the basis of its anti-inflammatory, anti-oxidant, and anti-apoptotic activities with recuperation of the testicular vascularity. Modulation of HIF/VEGF and cAMP/SIRT1 pathways showed a great role in mediating such effect.

Abstract
This study aimed to investigate the protective effect of sinapic acid (SA) on biochemical and histopathological changes in an experimental testicular torsion-detorsion rat model. Twenty-four rats were randomised into four groups: sham group, ischemia/reperfusion (IR) group subjected to testicular torsion for 2 hr and then detorsion for 4 hr, and two groups treated with SA1 and SA2 (10 mg/kg and 20 mg/kg, by single intraperitoneal injection, 30 min before reperfusion). Serum testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were measured by an autoanalyzer, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), protein carbonyl (PC), and nitric oxide (NO) oxidative stress parameters by spectrophotometric methods, and tumour necrosis factor (TNF-α), interleukin-1 beta (IL-1β), and interleukin 6 (IL-6) parameters by the Elisa method. In addition, immunohistochemical and histopathological examinations were performed on testicular tissues. There was no significant difference between the groups in terms of serum testosterone, FSH and LH levels (p > .05). SA significantly reduced increased testicular damage, oxidative stress, inflammation, cell death and also restored decreased antioxidant enzyme activities (p < .05). Pre-treatment of rats with SA reduced testicular dysfunction and morphological changes IRI. SA's antioxidant, anti-inflammatory, and antiapoptotic properties were found to be protective against testicular IR.

Effects of platelet-rich plasma on spermatogenesis and hormone production in an experimental testicular torsion model. Andrology 2021; 9:407-413. [PMID: 32866352 DOI: 10.1111/andr.12895] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2020] [Revised: 08/06/2020] [Accepted: 08/22/2020] [Indexed: 12/15/2022]
Abstract
BACKGROUND Platelet-rich plasma is a biological instrument rich in growth factors and cytokines. OBJECTIVES The aim of this study was to investigate the effect of platelet-rich plasma on spermatogenesis and hormone production in an experimental testicular torsion model. MATERIALS AND METHODS The rats were randomly divided into three groups, including six rats in each group as follows: the first group as the sham group; the second group as the ischemia/reperfusion + Saline group and the third group as the ischemia/reperfusion + platelet-rich plasma group. The left testicles of the ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma group were kept in four-hour torsion. Then, the left testicles of ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma groups were detorsioned, and intra-testicular 1 cc saline (ischemia/reperfusion + Saline) and 1 cc platelet-rich plasma (ischemia/reperfusion + platelet-rich plasma) were injected. At one month, blood samples were taken from all groups for hormonal evaluation and left orchiectomy was performed. RESULTS The mean follicle-stimulating hormone level of ischemia/reperfusion + Saline group was significantly higher than ischemia/reperfusion + platelet-rich plasma group (7.78 ± 0.23 vs 6.18 ± 0.28 nmol/l, respectively, P = .004). The mean LH level of ischemia/reperfusion + platelet-rich plasma group was significantly lower than ischemia/reperfusion + Saline group (3.63 ± 0.28 vs 5.68 ± 0.21 nmol/l, respectively, P = .004). The mean total testosterone level of ischemia/reperfusion + platelet-rich plasma group was significantly higher than ischemia/reperfusion + Saline group (8.05 ± 0.24 vs 5.78 ± 0.23 nmol/l, respectively, P = .004). The mean Johnsen scores of ischemia/reperfusion + platelet-rich plasma group were significantly higher than ischemia/reperfusion + Saline group (5.85 ± 0.58 vs 3.93 ± 0.65, respectively, P = .004). The mean Johnsen score of the sham group was significantly higher than ischemia/reperfusion + platelet-rich plasma and ischemia/reperfusion + Saline groups (P = .003 and P = .003, respectively). DISCUSSION AND CONCLUSION The platelet-rich plasma has beneficial effects on spermatogenesis and reproductive hormone production in testicular torsion. It is easily accessible and applicable. In the future, intra-testicular platelet-rich plasma injection may be used in testicular torsion after detorsion. However, further experimental and large-scale prospective clinical studies are needed to establish a definitive conclusion on this topic.
