Antiseptic agents used in the postoperative period affect the functions of many tissues in the body, including the testicles. In this study, the effect of dressings administered with different antiseptic agents on testicular functions in rats that underwent abdominal incisions was investigated. A total of 48 Sprague-Dawley rats were used in the study. Each of the rats in the study group underwent a 4 cm-long skin and muscle operation. The incision was then stitched immediately Antiseptics, hemp seed oil, hemp leaf oil, and cannabidiol oil were then administered to the rats for 10 days to provide antisepsis. The rats were sacrificed 24 hours after the last administration, and testicular tissues were removed. Testicular tissues were used for histopathological examination and biochemical analysis, while epididymal tissue was used for sperm analysis. According to the results, the MDA level in the antiseptic-administered group was higher than in the other experimental groups (p<0.05). Levels of SOD, CAT activities, and GSH content were found to be lower in the antiseptic group than in the hemp seed oil, hemp leaf oil, and cannabidiol oil groups (p<0.05). In testicular histology, the SEED group had the highest Johnsen score, and the antiseptic group had the lowest score (p<0.05). While JAK, P-JAK2, STAT3, PSTAT3, and NF-κB were generally higher in the antiseptic group compared to the other groups, they were lower in the SEED group. Additionally, sperm total motility rate and epididymal sperm density were highest in the SEED group (p<0.05). As a result, it was determined that cannabidiol seed oil had a good effect on testicular histology and sperm quality in male rats during the wound healing process.

The aim of the present study was to determine the effects of Luteolin (LUT) on semen quality, oxidative stress, apoptosis, acrosomal integrity, mitochondrial membrane potential and dead sperm ratio in rabbits. Ejaculates from six New Zealand rabbits were collected, evaluated and pooled. The pooling was divided into five groups as control (no additive) LUT 25 μM, LUT 50 μM, LUT 100 μM and LUT 200 μM and LUT added. It was then filled into a falcon tube with Tris-based extender at a final concentration of approximately 35 x 106 spermatozoa. Diluated rabbit semen samples were drawn into frozen and thawed. Frozen semen straws were thawed at 37°C in 30 seconds. According to our findings, no statistical difference was found between all doses of luteolin and the control group in the CASA (computer assisted sperm analysis) analysis performed at 4°C. However, total motility, progressive motility and rapid sperm percentage were found to be higher in the frozen and thawed rabbit semen at a dose of LUT 50 μM compared to the other groups (p<0.05). While amplitude of lateral head displacement (ALH) and beat cross-frequency (BCF) values were found at the lowest dose of LUT 200 μM, a statistically significant difference was observed between the other groups. When the flow cytometry results were examined, no statistical difference was found between the rate of dead sperm, acrosomal integrity, mitochondrial membrane potential and apoptosis rate. Morever, the H2O2 percentage was found to be lower in all experimental groups compared to the control group (p<0.001). In conclusion, the addition of LUT in long-term storage of rabbit semen provided a protective effect for spermatozoa with its antioxidative properties against damage caused by cryopreservation.

Bisphenol A (BPA), an endocrine disrupting chemical, is an environmental toxicant widely used in the production of polycarbonate plastics, epoxy resins and paints. Ganoderma lucidum (GDL) is a plant with biological activities widely used in Chinese medicine. The present study aims to determine the effects of GDL against testicular dysfunction in rats exposed to BPA. For this purpose, a total of 24 Sprague Dawley rats, 6 rats in each group, were used in the study Rats were administered 25 mg/kg/bw BPA and 300 mg/kg/bw GDL by oral gavage for 8 weeks. After the treatments, the rats were sacrificed, and testicular tissues were removed. One of the testes was used for biochemical analyses and the other for histopathologic examinations. The caudal part of the epididymis was trimmed, and semen was obtained. As a result, BPA increased MDA level in blood and testicular tissue, while it decreased CAT, GPx activity and GSH level. GDL treatment provided protection from the impaired oxidant balance (p<0.001). Furthermore, BPA caused decreased epididymal sperm motility and density, vesicular seminalis weight and blood testosterone levels, increased testicular and epididymal tissue weight (p<0.001). Histopathological examination revealed that BPA caused narrowing in testicular tubules and apoptosis, decreased germinal cell thickness and androgen receptor number. It was determined that GDL administration preserved testicular histology. As a result, it was determined that BPA caused toxicity in the testicular tissue of rats, whereas GDL administration was ameliorative.

In this study, the effects of in-ovo injection of Chrysin (CR) into Japanese quail eggs on testicular histology, oxidant status and epididymal sperm quality were investigated. 720 Japanese quail eggs were divided into 4 groups and 0.1 mL saline was given to the control group, 0.25 mg CR to the 0.25 group, 0.50 mg CR to the 0.50 group and 0.75 mg CR to the 0.75 group. On the 60th day after the laying of eggs, 8 Japanese quails were randomly selected from each group and sacrificed under mild sevoflurane anesthesia. The abdominal cavity was opened and both testicular tissues and epididymal parts were removed. The right testicular tissue was used for histopathological examinations and the left one was used for biochemical analyses. The epididymal part at the tip of the vas deferens at the end of the right testis was trimmed in 100 μL saline at 37°C. Histopathological examinations showed that histological scoring was higher in the CR 50 and CR 75 groups. A decrease in oxidant status was observed in all CR groups compared to the control group. Spermatozoa density was higher in CR groups compared to the control group. Total motility value was statistically significantly higher in CR 50 and CR 75 groups compared to control and CR 25 groups. There was no statistical difference between the groups in terms of dead and abnormal spermatozoa. In-ovo CR injection at doses of 0.50 and 0.75 mg/egg improved testicular histological score, decreased oxidative stress, and increased epididymal sperm quality.
