Nano Spirulina platensis countered cisplatin-induced repro-toxicity by reversing the expression of altered steroid hormones and downregulation of the StAR gene.

Cisplatin is a commonly utilized chemotherapy medication for treating different sarcomas and carcinomas. Its ability interferes with cancer cells' DNA repair pathways and postpones unfavorable outcomes in cancer patients. The current investigation's goal was to ascertain if nano Spirulina platensis (NSP) might shield rat testicles from cisplatin damage by assessing the expression of the StAR and SOD genes, sex hormones, 17ß-hydroxysteroid dehydrogenase(17ß-HSD), sperm profile picture, oxidative condition of testes, testicular histology, and DNA damage. Four equal and random groups of 28 adult male Wistar rats were created; the control group was given saline for 8weeks. An extraction of NSP at a concentration of 2500mg/kg body weight was administered orally for 8weeks to the NSP group. For the first 4weeks, the cisplatin group was intraperitoneally injected with 2mg/kg/body weight of cisplatin, and for the next 4weeks, they were given a dosage of 4mg/kg/body weight. The cisplatin + NSP group was given both NSP and cisplatin. The results of the experiment showed that intake of NSP and cisplatin improved sperm profile; re-established the balance of oxidizing agents and antioxidant state; enhanced testicular histology; promoted the histometric parameters of seminiferous tubules including epithelial height, their diameter, and Johnsen's score, decreasing DNA breakage in testicular tissue; increased testosterone level; decreased 17ß-HSD concentration; and upregulated both the StAR and SOD gene expression in testicles compared to rats exposed to cisplatin alone. These results demonstrate that NSP is a promising agent for improving cisplatin-induced testicular injury and infertility.

The Toxic Effect of Bisphenol A on Male Rat Testicles and The Possible Protective Value of Propolis and Vitamin E

This study aimed to examine the impact of propolis (Pro) on various physiological parameters in male rats experiencing induced testicular dysfunction by Bisphenol A. Five groups of ten male rats apiece were created by random selection from the rats. Group 1 the rats, which performed as the group under negative control, received normal food and water. In Group 2, rats were subjected to intraperitoneal administration of 0.2 mL of corn oil, utilized as the vehicle for bisphenol A (BPA), thereby serving as the vehicle control group. For Group 3, rats were administered in corn oil, BPA dissolved at a dosage of 50 mg/kg body weight administered three times a week for three weeks using an intraperitoneal injection. In Group 4rats received a dose of 250 mg/kg body weight of propolis (protected) orally via a gavage needle. Subsequently, intraperitoneal injections are administered to them from BPA delivered three times weekly for three weeks, the dosage is 50 mg per kilogram of body weight dissolved in corn oil. In Group 5, rats received protection with vitamin E orally, at a dose of 100 mg/kg body weight, using a gavage needle. The intraperitoneal injection of BPA, dissolved in corn oil at a dose of 50 mg/kg body weight, was then given three times a week for three weeks. After three weeks, animals were sacrificed, and testes and blood were gathered for additional analysis. Superoxide Dismutase (SOD), Sperm Viability, General motility, Progressive motility, and Morphology, were all significantly reduced in the BPA group compared to the control groups, according to the results. While malondialdehyde (MDA) increased in the BPA group compared to the control groups. In conclusion, propolis enhanced physiological parameters adversely affected by BPA, suggesting its potential as a protective agent against BPA-induced testicular dysfunction.

Protective effect of curcumin on testicular damage caused by carbon tetrachloride exposure in rats.

Context Carbon tetrachloride (CCl4 ) is a chemical that is still widely used in industry and has been shown to cause structural defects in rat testicles through oxidative stress. Aims In our study, the effect of curcumin on CCl4 -mediated testicular damage was investigated. Methods Twenty-four adult Wistar albino male rats weighing 300-350g were divided into four groups: control group (olive oil was applied by gavage every consecutive day for 3weeks); curcumin and CCl4 +curcumin groups (200mg/kg curcumin dissolved in olive oil was given by gavage once a day, every consecutive day for 3weeks); and CCl4 and CCl4 +curcumin groups (0.5mL/kg CCl4 was dissolved in olive oil at a ratio of 1/1 and given by i.p. injection every other day for 3weeks). Tissue samples were examined histopathologically, histomorphometrically, immunohistochemically and biochemically. Key results CCl4 disrupted both testicular morphology and testosterone synthesis, whereas curcumin treatment resulted in an improvement in testicular morphology and biochemical parameters, as well as a decrease in caspase-3 and tumour necrosis factor-α expression. Conclusions Curcumin has a protective effect on testicular tissue damage caused by CCl4 with its anti-inflammatory, antiapoptotic and antioxantioxidant properties. Implications Curcumin can prevent testicular damage due to CCl4 , an environmental pollutant.

TRapamycin reduces testicular ischemia-reperfusion injury by enhancing autophagy

Objectives To confirm the effects of autophagy on testicular ischemia-reperfusion (I/R) injury. Methods Forty rats were divided into sham group, I/R group, I/R+Rap (rapamycin, autophagy activator) group and I/R+ 3-MA (3-methyl adenine, autophagy inhibitor) group. Before inducing ischemia, rapamycin and 3-MA were intraperitoneally injected into I/R+Rap and I/R+ 3-ma groups, respectively. Subsequently, we then assessed testicular tissue damage. Immunohistochemistry was used to detect Beclin-1 and Caspase-3, while Western blot and qRT-PCR detected LC-II, Beclin-1 and p62. TUNEL and transmission electron microscopy were used to observe apoptosis and autophagosome. Results I/R activated autophagy in rat testicles. Rapamycin significantly improved testicular function after I/R by enhancing autophagy, reducing spermatogenic cell apoptosis, and decreasing testicular tissue damage scores. Conclusions Enhancing autophagy has a protective effect in ischemic-reperfusion injury by reducing apoptosis of rat testicular sperm cells.

The Effect of Giving Butterfly Pea Flower Extract (Clitoria ternatea) on Reducing Cholesterol Levels and Histopathological Features of White Rat Testes (Rattus norvegicus) Wistar Male Obesity Model

Obesity is a global, non-communicable condition that causes male infertility. Obesity impacts spermatogenesis and male fertility. Butterfly pea blossoms (Clitoria ternatea) contain antioxidants that fight free radicals and prevent obesity. This research looked at how butterfly pea flower extract (Clitoria ternatea) affected cholesterol levels, testicular function, and the histopathology of the testicles of obese male Wistar rats (Rattus norvegicus). This research is quantitative and uses a lab or actual experiment. The 24 test mice were randomly divided into four groups. The research data was analyzed using SPSS 25.0 for Windows. The normality test significance is 0.577. One-way ANOVA test results demonstrate 0.000 or greater than 0.05 significance. LSD post-hoc test values. The control and treatment groups 1–3 differed significantly (p = 0.000). No change was seen between treatment groups 2 and 3 (p = 0.088). The research found butterfly pea flower extract therapy (Clitoria ternatea) at 400mg and 600 mg/kgBW lowers cholesterol. Flavonoids, saponins, tannins, and triterpenoids reduce cholesterol and improve testicular function in obese white rats.

Alpha-pinene alleviates CCl4-induced renal and testicular injury in rats by targeting oxidative stress, inflammation, and apoptosis.

Renal and testicular disorders are primarily associated with oxidative damage and inflammation. Here, alpha-pinene (a type of monoterpene) was investigated for its effect on oxidative/nitrosative stress and the expression of inflammatory and apoptotic factors in the kidneys and testes of rats treated with CCl4. CCl4 was injected intraperitoneally (IP) at a dose of 2 ml/kg (twice a week for six weeks). Alpha-pinene (50 mg/kg/day, IP) was also treated during the same period. CCl4 increased the level of malondialdehyde (P<0.01 in the kidney and P<0.001 in the testis) and nitric oxide (P<0.001 in the kidney and P<0.01 in the testis) and decreased the levels of glutathione (P<0.05) in the kidneys and testicles of rats. CCl4 also reduced the catalase enzyme activity in the kidneys (P<0.05) but did not affect its activity in the testis. In addition, CCl4 enhanced the mRNA expression of TNF-α (P<0.01), nuclear factor-κB (P<0.05), and Bax (P<0.05 in the kidney and P<0.01 in the testis) and decreased the expression of Bcl-2 (P<0.05) in both organs. Alpha-pinene prevented all the mentioned changes, but it did not influence the expression of Bcl-2 in the kidneys of rats receiving CCl4. Alpha-pinene may have the potential to prevent renal and testicular diseases by strengthening the antioxidant system in the kidneys and testis, and inhibiting oxidative/nitrosative stress, inflammation, and apoptosis caused by CCl4.

Zuogui Pills improve testicular development of offspring rats exposed to prenatal stress via Cx43

This study aims to reveal the mechanism of prenatal stress in affecting the testicular development of offspring rats and the intervention effects of Zuogui Pills via connexin 43(Cx43). Forty pregnant SD rats were randomized into a blank control group, a mo-del group, a high-dose(18.9 g·kg~(-1)) Zuogui Pills group, a low-dose(9.45 g·kg~(-1)) Zuogui Pills group, and a vitamin E(1.44 mg·kg~(-1)) group. The other groups except the blank control group was subjected to chronic unpredictable mild stress for the modeling of prenatal stress. The model was evaluated by sucrose preference test, open field test, and enzyme-linked immunosorbent assay(ELISA) of the glucocorticoid level. ELISA was employed to measure the thyroxine 4(T4), testosterone(T), and follicle-stimulating hormone(FSH) levels to assess kidney deficiency. Hematoxylin-eosin(HE) staining was employed to evaluate the status of testicular germ cells. An automatic sperm analyzer was used to measure the sperm quality. Immunofluorescence double staining was employed to detect the expression of Cx43 and follicle-stimulating hormone receptor(FSHR) in the testes of offspring rats. The mRNA and protein levels of Cx43, FSHR, phosphatidylinositol 3-kinase(PI3K), and protein kinase B(Akt) were determined by real-time fluorescence quantitative polymerase chain reaction and Western blot, respectively. Prenatal stress induced testicular development disorders in offspring rats. The HE staining results showed that on the day of birth, the model group had reduced seminiferous tubules in the testes, elevated FSH level in the serum, and lowered Cx43 level in the testicular tissue. Male offspring rats of 60 days old had reduced testicular spermatogenic function, decreased sperm quality, elevated FSH level and lowered T level in the serum, and down-regulated protein and mRNA levels of Cx43, FSHR, PI3K, and Akt in the testicular tissue. Zuogui Pills alleviated the abnormal development and dysfunction of testicles in the offspring rats caused by prenatal stress. In summary, Zuogui Pills may weaken the effects of prenatal stress on testicular development and spermatogenic function of offspring rats by activating the PI3K/Akt pathway to regulate Cx43 expression in the testicular tissue.

The structural rearrangement of testicular arteries in case of chronic ethanol intoxication

Prolonged poisoning of the body with ethanol damages almost all its organs and systems. Structural changes in testicular arteries under the influence of chronic ethanol intoxication have not been fully studied. Purpose - to analyze the morphometric parameters of the small caliber arteries of the right and left testicles of rats in case of chronic ethanol intoxication. Materials and methods. 62 laboratory sexually mature male rats was performed. The animals were divided into two groups. The Group 1 (control) included 30 rats, the Group 2 (experimental) - 32 animals. The experimental rats, which were conducted to the experiment, were injected intragastrically with a 30% ethanol solution at the rate of 2 ml per 100 g of body weight for 28 days once a day. Animals were euthanized by heart bleeding under thiopental anesthesia. Histological micro-sections were made from the left and right testicles. Morphometrically, the outer and inner diameters of the arteries, media thickness, adventitia, Vogenvoort and Kernogan indices, the height of endotheliocytes, the diameter of their nuclei, the nuclear-cytoplasmic ratio in these cells, and the relative volume of damaged endotheliocytes were determined morphometrically in small-caliber arteries. Statistical processing of digital data was carried out using Excel (Microsoft, USA) and STATISTICA 6.0 (Statsoft, USA) software. Results. It was established that in case of simulated experimental conditions of chronic ethanol intoxication, the investigated morphometric parameters of the arteries of the left and right testicles changed significantly. In case of chronic intoxication with ethanol in rats, pronounced structural rearrangement of testicular vessels, mainly small arteries, characterized by thickening of the blood vessel’s wall, narrowing of vessels’ lumen, rearrangement of endothelial cells, and an increase in the relative volume of the damaged cells of intima, is established, and is dominant in the left testis. Conclusions. In case of chronic intoxication with ethanol the structural changes in testicular tissues are dominant in the left testis. Pronounced remodeling of small caliber testicular arteries causes endothelial dysfunction, deterioration of blood supply to the testicles, hypoxia, dystrophic and necrobiotic tissue changes, infiltrative and sclerotic processes, which are the pathomorphological basis of male infertility. When carrying out experiments with laboratory animals, all bioethical norms and recommendations were observed. No conflict of interests was declared by the authors.

Electron microscopic changes in interstitial endocrinocytes of rats testicles during administration of triptorellin for 365 days

Triptorelin is a gonadotropin-releasing hormone agonist that is a potent inhibitor of testosterone (in men) and estrogen (in women) synthesis and is used to treat advanced prostate cancer. Studies of the mechanisms of regulation and synthesis of testosterone formation in testicular interstitial cells demonstrate multiple endogenous targets that can increase testosterone biosynthesis, which may moderate the effects of testosterone depletion. Triptorelin, a synthetic analog of the neurohormone gonadoliberin, suppresses the expression of the GnRH receptor in the pituitary gland, but does not change the functioning of the pituitary-testicular complex. The purpose of the work is to study the electron microscopic changes in the interstitial endocrinocytes of the testes of rats after the administration of triptorelin for 365 days. The experiment was conducted on 35 sexually mature male white rats. The rats were divided into 2 groups: the control group (I) was injected with a physiological solution, the II group with central deprivation of the synthesis of luteinizing hormone was injected subcutaneously with triptorelin at a dose of 0.3 mg of the active substance per kg of the rat's body weight. The study of the interstitial space in the testicles of white rats showed that long-term administration of triptorelin causes hormonal dysregulation of the hypothalamus-pituitary-testis system, which leads to quantitative and qualitative changes in the endocrine cells of the interstitial space of the testis, which is confirmed by electron microscopic changes in subcellular structures. The maximum effect of triptorelin is determined from the 180th day of observation, which is characterized by an increase in degenerative changes in endocrinocytes, and the detection of Reinke crystals in the cytoplasm of interstitial endocrinocytes from the 270th day of observation.

The greater omentum and similar serous formations of testis in male white rats.

The greater omentum of white rats appears, in basic morphological features (in miniature), to be homologous to the greater omentum of humans. We study of the greater omentum reaction to the catgut implant. After implantation of the catgut thread, it turned out that not only the greater omentum, but also serous formations similar to it, related to the testicles, are involved in the covering of the implant. The aim of the study was to study the general plan of the structure and the principles of morphometric analysis of serous formations of testis in white male rats. The experiment involved 15 white male rats of reproductive age, weighing from 284 to 334 grams. It has been established that each testicle of white rats has serous (peritoneal derivatives) formations of two types. One of them is a typical mesentery, with which each testicle is separately fixed to the posterior wall of the pelvic cavity, and the other formation is a free regrowth of a duplication of the serous membrane. It was called the epididymal omentum. According to the algorithm for studying the greater omentum in our previous works, it is noteworthy that the area of the greater omentum is noticeably inferior to the area of the epididymal omentums (F = 0.239; p = 0.006). So, if the average value of the area of the greater omentum is 2766.51 ± 388.12 mm2, then the same indicator of the epididymal omentum reaches 4383.36 ± 793.56 mm2, with their approximately the same thickness (F = 1.35; p = 0.291). It has been established that the greater omentum has two, homeomorphic to it, derivatives of the peritoneum, associated with the epididymis, which were justifiably called epididymal omentums and were fully described in the literature for the first time.

Investigation of the Effect of Quercetin in Experimental Ischemia-Reperfusion Injury Model in Rat Testicle

Testicular torsion (TT) is the most important cause of acute scrotum in childhood. It is an emergency surgical problem that can lead to loss of organ if left untreated. The aim of treatment is to reduce or eliminate the torsion/detorsion damage. The affect of antioxidants is one of the methods to be used for this reason. In this study, a special bioflavonoid and quercetin, an antioxidant known to protect against oxidative damage, were used to avoid experimentally caused torsion/detorsion damage in rats.&#x0D; 32 male Sprague Dawley rats, 12 weeks old, weighing 250–300 g, were used in the study.Rats were randomized into 4 groups. No surgical procedure was performed in the control group. 5-hour ischemia was achived by applying torsion to the left testicle in the torsion group. After 5 hours of ischemia, a 2-hour reperfusion was applied in the torsion/detorsion group. In the torsion/detorsion+quercetin group, 2 hours of reperfusion was applied after 5 hours of ischemia and i.p. quercetin was injected.&#x0D; A significant decrease was observed in the quercetin-administered group in terms of spermatocyte degeneration and inflamation. There was a decrease in dilatation data in the quercetin group, but it was not statistically significant.&#x0D; Quercetin, which has a strong antioxidant effect, has been shown to have positive effects on experimentally induced torsion/detorsion damage.&#x0D; Keywords: Testicular torsion, ischemia-reperfusion, antioxidan, quercetin, Inflammation

Casein and pea enriched high-protein diet attenuates arsenic provoked apoptosis in testicles of adult rats.

Arsenic toxicity is a major health issue that also threats male reproductive system leading to impairment of fertility. The antioxidant capacity of casein and pea enriched formulated high-protein diet (FHPD) is found to be effective in different toxicity management. The present study was endeavored to investigate the mitigatory aspect of FHPD on arsenic stimulated testicular apoptosis. Adult male rats were maintained on either normal diet as control (Gr I, n=8) and arsenic (As2O3) treated at a dose of 3mg/kg/rat/day (Gr II, n=8) or on isocaloric FHPD as supplemented (Gr III, n=8) with same dose of arsenic for 30 consecutive days. Testicular histomorphometry, spermatokinetics, testicular functional marker enzymes, serum gonadotrophins, oxidative stress markers, testicular deoxyribonucleic acid (DNA) damage, and apoptosis markers were evaluated to assess the reprotoxicity of arsenic and subsequent protection by FHPD. FHPD protected the histopathological alterations and also restored normal spermatogenesis. Altered enzymatic activities of testicular functional markers like lactate dehydrogenase, γ-glutamyl transferase, acid phosphatase, and alkaline phosphatase were also regularized. FHPD also reinstated the normal level of follicle stimulating hormone (FSH), luteinising hormone (LH), and also normalized the enzymatic activities of testicular glutathione peroxidase and glutathione reductase. Testicular DNA damage was also prevented by FHPD supplementation. Testicular apoptosis marked by the altered messenger ribonucleic acid and protein expression of apoptotic markers like Bax, Bcl-2, caspase 9, and caspase 3 were also attenuated upon FHPD supplementation along with diminution of arsenic accumulation in testicular tissues. FHPD not only mitigated the adverse effects of arsenic induced gonadotoxicity but also helped in sustaining the normal reproductive functions.

The effect of smoking and electronic cigarettes on rat testicles

ObjectiveAfter the negative effects of smoking on public health were proven, smoking cessation campaigns were initiated by health ministries and non-governmental organizations. Many drugs have been tried to reduce the addiction to smoking and the nicotine contained in it. Recently, e-cigarettes (EC) are widely used for smoking cessation efforts, although the effects and possible harms are not fully known. In our study, we planned to show the effect of cigarette and EC smoke on the male urogenital system. MethodsAdult male wistar rats were exposed to cigarette and EC smoke in a specially designed glass bell jar. Urine cotinine levels, testicular weights, gonadosomatic index, sperm count and sperm motility, testicular histology, and biochemical findings were compared with the control group. ResultsIn some rats in the cigarette and EC group, the seminiferous tubules were disorganized, and the germ cells and Sertoli cells were separated and shed. Stopped germ cell separation, cavity formation, necrosis, fibrosis, and atrophy were observed in severe cases. Higher PCO levels were found in the cigarette group compared to controls. Tissue homogenates levels of LPO were higher in both EC and cigarette groups compared to controls. No significant differences were observed between groups in terms of sperm motility and sperm count. ConclusionCigarette and EC liquid can increase oxidative stress as well as cause morphological changes in the testicle. To be a safe option in smoking cessation studies, its effect on people needs to be enlightened.

Effects of the apricot diets containing sulfur dioxide at different concentrations on rat testicles.

Due to its antioxidant and antimicrobial properties, sulfur dioxide (SO2) is widely used in foods and beverages to prevent the growth of microorganisms and to preserve the color and flavor of fruits. However, the amount of SO2 used in fruit preservation should be limited due to its possible adverse effects on human health. The present study was designed to investigate the effects of different SO2 concentrations in apricot diets on rat testes. Animals were randomly divided into six groups. The control group was fed a standard diet, and the other groups were fed apricot diet pellets prepared with (w/w) 10% dried apricots containing SO2 at different concentrations (1500ppm, 2000ppm, 2500ppm, 3000ppm, and 3500ppm/kg) for 24weeks. After sacrification, testicles were evaluated biochemically, histopathologically, and immunohistopathologically. Our results showed that an apricot diet containing 1500ppm and 2000ppm SO2 did not cause significant changes in testis. However, it was determined that tissue testosterone levels decreased as the amount of SO2 (2500ppm and above) increased. Apricot diet containing 3500ppm SO2 caused a significant increase in spermatogenic cell apoptosis, oxidative damage, and histopathological changes. In addition, a decrease in the expression of connexin-43, vimentin, and 3β-hydroxysteroid dehydrogenase (3β-HSD) was observed in the same group. In summary, the results show that sulfurization of apricot at high concentrations such as 3500ppm may lead to male fertility problems in the long term through mechanisms such as oxidative stress, spermatogenic cell apoptosis, and inhibition of steroidogenesis.

Protective effectiveness of anise against testicular ischemia and reperfusion injury: An experimental study in rats.

Testicular torsion is a frequently encountered clinical condition that requires urgent treatment. The aim of this study is to investigate the efficacy of Anise (Pimpinella anisum L.) in treating the pathological condition due to ischemia and reperfusion injury by using biochemical, histopathological and immunohistochemical methods. A total of 6 groups were formed with 8 male Wistar Albino rats in each group. Group 1 (n=8): control group, Group 2 (n=8): Anise aqueous solution was given orally 5 ml/kg by gavage for 30 days. Group 3 (n=8): Ischemia and Reperfusion (I/R) group, bilateral testicles were rotated 270° and reperfused after 30 minutes of ischemia. Group 4 (n=8): I/R+ Anise group, Group 5 (n=8): Anise+ I/R group and Group 6 (n=8): Anise+ I/R+ Anise group. The results of the Anise group and the Control group were similar. However, the damage in the I/R group was considerably more severe than in any of the other study groups. While it was observed that spermatogenic cells started to regenerate in the I/R+Anise group, edema and congestion were observed in the Anise+I/R group. In the Anise+I/R+Anise group, all histological findings and biochemical parameters were similar to those of the control group. It was observed that anise had protective effects in ischemia and reperfusion injury in rat testicles.

Ameliorative effects of nano Moringa on fluoride-induced testicular damage via down regulation of the StAR gene and altered steroid hormones

Fluoride is a common environmental contaminant that has harmful effects on human health when it is present in high concentrations. Fluoride enters the bloodstream after being absorbed by the gastrointestinal system when fluoride-contaminated groundwater is consumed by people. The aim of the present study was to determine whether polyphenol-rich nano Moringa oleifera (NMO) could protect rat testicles from sodium fluoride (NaF) damage by evaluating sperm quality, sex hormones, testicular oxidative status, histopathology, and StAR gene expression. Twenty-eight adult Wistar rats were divided equally and randomly into four groups: group one received distilled water; group two received NMO at a dosage of 250mg/kg/body weight; group three received NaF at a dosage of 10mg/kg/body weight; and group four received NaF and NMO. The rats were orally administrated daily for a duration of eight weeks. The study's findings demonstrated that, in comparison to rats exposed to NaF alone, co-administration of NMO and NaF enhanced sperm motility and viability, decreased sperm morphological changes, restored the balance between oxidant and antioxidant status, improved testosterone and dehydroepiandrosterone, improved testicular histology, raised the Johnson score, and upregulated the StAR gene in testicular tissue. These findings show that NMO is promise as a prophylactic medication against sodium fluoride-induced testicular damage because administration of NMO had no adverse effects and enhanced reproductive health.

The role of cur ole of curcumin against paclitax cumin against paclitaxel-induced o el-induced oxidativ xidative stress and DNA damage in testes of adult male rats.

Paclitaxel is a widely used drug for the treatment of cancer, but it possesses toxic effects on male reproductive system. Administering paclitaxel with an antioxidant has become a strategy for preventing the side effects of paclitaxel. Although curcumin is an antioxidant, data concerning the effect of curcumin on paclitaxel-induced testis tissue are lacking. The present study was established to examine the protective impact of curcumin against testicular damage induced by paclitaxel. In the study, 40 Wistar albino male rats were used and randomly divided into 4 groups (n:10). The control group received only saline solution; the curcumin group received curcumin throughout the experiment; the paclitaxel group received a total of four doses of paclitaxel on days 1, 7, 14, and 21 of the experiment; curcumin + paclitaxel group received curcumin throughout the experiment and a total of four doses of paclitaxel on days 1, 7, 14, and 21 of the experiment. At the end of the experiment, the rats were decapitated under xylazine and ketamine anesthesia and their testicles were removed. The sections obtained from the testicles were stained with Hematoxylin & Eosin and histopathological damage was evaluated. The TUNEL method was applied to determine apoptotic cells. Testosterone levels were measured in the blood serum. The Johnsen testicular biopsy score (JTBS) was used to evaluate testicular tubules. DNA damage was evaluated in sperm samples taken from the ductus epididymis using the comet assay technique. Testicular tissue was severely damaged in the paclitaxel group. In the curcumin + paclitaxel group, it was determined that the administration of curcumin with paclitaxel reduced the histological damage in the testicular tissue. Moreover, according to the JTBS, the value was significantly higher in the testicular tubules (p < 0.05). Testosterone levels were higher in curcumin + paclitaxel group than in paclitaxel group. DNA damage also decreased significantly in curcumin + paclitaxel group when compared to paclitaxel group (p < 0.05). The results showed that curcumin may be protective against damage caused by paclitaxel in the testicles of rats.
