Seasonal Alterations in Testicular Hemodynamics and Echotexture in Relation to Semen Quality in Buffalo Bulls

Diabetes mellitus (DM) provokes reproductive impairments through endocrine disturbance, sperm deficits, and testicular oxidative inflammation. The study investigated the reproductive protective effects of resveratrol (RSV) against testicular oxidative inflammation, sperm/endocrine deficits, and insulin resistance in streptozotocin- (STZ-, 65 mg/kg) induced DM rat model. Male rats were randomly divided into 4 groups (<span class="inline_break"><svg xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg" width="17.789pt" style="vertical-align:-0.2063904pt" id="M1" height="8.55521pt" version="1.1" viewBox="-0.0498162 -8.34882 17.789 8.55521"><g transform="matrix(.013,0,0,-0.013,0,0)"><path id="g113-111" d="M495 86L479 114C446 82 419 66 409 66C401 66 401 72 406 97C420 166 436 231 453 297C489 435 454 448 428 448C406 448 384 439 354 422C305 394 222 327 161 247H159L183 345C200 415 194 448 173 448C143 448 82 410 23 351L38 325C64 349 95 371 105 371C111 371 116 365 109 336L25 -4L31 -12C50 -4 77 3 107 9C119 69 132 122 145 168C197 254 321 381 370 381C387 381 393 374 378 305L329 95C309 17 320 -12 345 -12C372 -12 430 19 495 86Z"/></g><g transform="matrix(.013,0,0,-0.013,10.158,0)"><path id="g117-34" d="M535 323V373H52V323H535ZM535 138V188H52V138H535Z"/></g></svg><span class="irelop"></span><span class="nowrap"><svg xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg" width="6.416pt" style="vertical-align:-0.2063904pt" height="8.55521pt" version="1.1" viewBox="21.3711838 -8.34882 6.416 8.55521"><g transform="matrix(.013,0,0,-0.013,21.421,0)"><path id="g113-55" d="M137 343C167 482 260 545 321 574C357 591 397 603 429 609L423 641C382 634 335 622 295 608C189 570 37 457 37 238C37 84 125 -12 242 -12C362 -12 447 89 447 209C447 311 374 393 267 393C247 393 226 386 204 376L137 343ZM227 337C318 337 361 256 361 173C361 105 336 22 258 22C176 22 126 120 126 240C126 266 127 291 132 310C155 323 189 337 227 337Z"/></g></svg>):</span></span> control, DM, RSV (150 mg/kg bw, orally), and RSV+DM group (21 days). The nontreated DM rats showed marked decreases in serum insulin, reproductive hormones (T, LH, and FSH), and lipid profile levels compared to control. The homeostatic index of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI) were adversely modulated. Sperm count and motility were profoundly decreased, whereas sperm abnormality was significantly increased. The testicular activities of catalase (CAT), glutathione peroxidase (GPx), superoxide dismutase (SOD), and malondialdehyde (MDA) level, along with inflammatory cytokines (TNF-<i>α</i>, IL-6, IL-4, and IL-10) were significantly dysregulated. The DM induced histopathological lesions compared to control rats. Interestingly, the RSV administration to DM rats attenuated the altered reproductive parameters, restored antioxidant mechanism, and anti-inflammatory responses with improved insulin resistance. RSV could prevent DM-induced reproductive deficits and insulin resistance via modulating oxidative stress-mediated testicular inflammation in rats.

Resveratrol Mitigates Diabetic Testicular Dysfunction, Endocrine Deficits, and Insulin Resistance via Suppression of Sperm-Endocrine Aberrations and Oxidative Inflammation in Rats

The effect of fluted pumpkin seeds (FPS) consumption on the antioxidant status of the testes of aged Wistar rats was evaluated in this study. Sixty (50 aged, 6 months old, and 10 young, 2 months old) rats were divided into six groups of 10 per each group. Testosterone (15 mg kg<sup>-1</sup> body weight, once weekly for 40 days) was injected intraperitoneally and used as positive control. FPS intake (50, 100, and 200 mg kg<sup>-1</sup> body weight) or vehicle control (corn oil) were administered orally, twice weekly for 40 days and compared with the untreated aged and young control rats. Changes in antioxidant status in the testis of the aged rats was reflected as increased superoxide dismutase and catalase activities and glutathione and decreased lipid peroxidation levels which were attenuated more efficiently by the lowest dose FPS (50 mg kg<sup>-1</sup> body weight). Additionally, nitrite concentration that was found to be diminished in the aged rats was raised to the young control values after intake of the FPS (50 mg kg<sup>-1</sup> body weight). As expected, testosterone injection increased endogenous testosterone concentration and also remained higher in the untreated aged animals than in young control and treated aged rats. In conclusion, compromised antioxidant defense system of the testes that is associated with ageing could be reversed to the status of the young control by the intake of FPS.

Intake of Fluted Pumpkin Seeds Rebalances Oxidative Stress Parameters in the Aged Rat’s Testes

Cadmium (Cd) is a toxic metal that damages several tissues of animals and humans including the testis. The ameliorative effects of quercetin (QUE), rutin (RUT), and gallic acid (GAL) at 20 mg kg<sup>-1</sup> body weight alone or in combination against testicular injury induced by Cd (24 mg kg<sup>-1</sup> body weight) in male Wistar rats were evaluated in this study. Forty-two (42) rats were randomly grouped into six (6) groups: (1) vehicle control group, (2) Cd group, (3) RUT+Cd group, (4) GAL+Cd group, (5) QUE+Cd group, and (6) RUT+GAL+QUE+Cd group. At the end of the oral gavage of the tested chemicals, the rats were sacrificed, blood samples were collected, and testes were harvested and processed for biochemical assays. Cd exposure damaged the testis (smaller epithelium thickness and spermatogenesis index and sloughing of the epithelium); increased lipid peroxidation, glutathione <i>S-</i>transferase activity, and DNA fragmentation; and diminished glutathione reductase activity and serum testosterone level 40 days posttreatment. Treatment with the phenolics separately or in combination attenuated the effect of Cd on serum testosterone, glutathione reductase and glutathione <i>S-</i>transferase activities, lipid peroxidation, and percent fragmented DNA. The increased nitric oxide concentration in the QUE+Cd group was attenuated to control values in the combined (RUT+GAL+QUE+Cd) exposure group. Coadministration of the phenolics appears to have more substantial protective effects than their single effects against Cd-induced testicular DNA damage, glutathione <i>S-</i>transferase activity, and the recovery of testosterone levels and spermatogenesis index. Overall, the tested phenolics can reduce testicular damage more efficiently in their combined form than individual administration.

Combined Protective Effects of Quercetin, Rutin, and Gallic Acid against Cadmium-Induced Testicular Damages in Young-Adult Rats

This prospective study is aimed at investigating the relationship between smartphone screen time and the intravaginal ejaculation latency time (IELT) in patients with acquired PE and to contribute to the literature. Thirty patients who had been diagnosed with acquired PE in our clinic between March 2022 and May 2022 were included in the study. Carrying similar demographic characteristics to the patient group, a total of 30 healthy volunteers were included as the control group. Patients who were using Huawei or iPhone brand of smartphones and who had data of at least one week of screen time were included in the study. The data were collected from the applications on the phones. PE was evaluated using PEDT, the Turkish validation of which had been carried out. The patients and the controls also underwent the application of the Quality-of-Life Questionnaire-Short Form (SF-36), which has also been validated for Turkish. The patients and the controls were compared with regard to smartphone screen time, IELT, PEDT scores, and the SF-36 scores. The mean screen time was found to be statistically significantly higher in the PE group compared to that of controls (<span class="inline_break"><svg xmlns:xlink="http://www.w3.org/1999/xlink"
