Korean red ginseng ( KRG) may be a beneficial adjuvant along with ciprofloxacin to ameliorate devastating effects of epididymo-orchitis ( EO) on male fertility. This study intends to assay the effects of KRG and ciprofloxacin on sperm quality and spermatogenic cells apoptosis in EO rats. We divided 54 adult rats into nine groups ( n = 6 rats per group): control ( CO), sham-operated ( SH), EO (E); ciprofloxacin (C), EO-ciprofloxacin ( EC), KRG (G), EO- KRG ( EG), ciprofloxacin- KRG ( CG) and EO-ciprofloxacin- KRG ( ECG). We administered ciprofloxacin and KRG 48 hr after the Escherichia coli (E. coli) injection for 10 days. Bilateral orchiectomy was performed after one sperm cycle (14 days) following the last treatment with ciprofloxacin and KRG. Total and progressive motility of E, C and EC groups decreased. However, motility is improved in CG and ECG in comparison with these groups. The E group induced negative changes in the architecture of testes tissue and dramatic increase in apoptosis indices. Interestingly, co-administration of ciprofloxacin and KRG has dramatically improved Miller's and Johnsen's scores and decreased the apoptosis indices of animals in the ECG group. Combined treatment of ciprofloxacin and KRG may improve the quality of spermatozoa and attenuated apoptosis indices in the ECG group. [ABSTRACT FROM AUTHOR]

The present study was carried out to examine first, if diets enriched with 320 g of the base diet with common dietary oils including fish oil, olive oil, hydrogenated sunflower seed (H-SFS) oil, flaxseed oil and sunflower seed oil (SFS) could induce weight gain and alter reproductive and metabolic characteristics of male mice. Second, whether the addition of conjugated linoleic acid (CLA, 10% of the diet) could ameliorate any negative effects. In this cross-sectional study, 90 four-week-old male NMRI mice were used in two consecutive experiments. A high level of dietary oils negatively affected some reproductive and metabolic characteristics of male mice (p < 0.05), specifically, sunflower seed oil enrichment resulted in higher HDL levels and apoptosis of germinal epithelial cells. An olive oil-enriched diet caused an increase in plasma triglyceride concentrations and germinal cell apoptosis, as well as a decrease in sperm concentration and perturbed spermatogenesis. When CLA was fed in conjunction with dietary oils it successfully mitigated some of the negative reproductive and metabolic characteristics. We conclude that male reproductive processes are affected by high dietary oils, even before signs of obesity are evident. Inclusion of dietary CLA may provide some benefit to offset negative effects, although further studies are required., (© 2022 Wiley-VCH GmbH.)

Insulin-like factor 3 (INSL3) has an important role in the human reproductive system; however, its detailed function is still mysterious. We aimed to investigate the possibility of expression of RXFP2 receptor on human spermatozoa and to determine the anti-apoptotic and antioxidant mechanism derived the binding of INSL3 and RXFP2. In this experimental study, the expression/location of the RXFP2 receptor was determined on the spermatozoa of fertile and infertile men. Twenty samples from 20 fertile men were collected and divided into 6 parts (control group, and five groups treated with INSL3 10, 100, 250, 500, 1,000 ng/ml). DNA damage, active caspase, reactive oxygen species (ROS) and sperm parameters were evaluated by TUNEL, flow cytometry, optical microscope and computer-assisted sperm analysis. The expression of RXFP2 was confirmed by Western blot. Immunocytochemistry illustrated that this receptor is expressed in the posterior half of the spermatozoa's head. The INSL3 at concentrations of 500 and 1,000 ng/ml reduced the active caspase and mitochondrial ROS, and also reduced DNA fragmentation at 1,000 ng/ml. Besides, INSL3 500 and 1,000 ng/ml significantly increased the sperm motility. This study confirmed the presence of RXFP2 receptor in fertile and infertile men's spermatozoa, indicating the highly dose-dependent efficacy of the INSL3, which may have promising impacts on the in-vitro fertilisation outcomes., (© 2020 Blackwell Verlag GmbH.)

Both epilepsy and valproate (VPA), as an antiepileptic drug, negatively affect male sexual function. The present study was conducted to evaluate the ameliorating impacts of ginseng on sperm quality, architecture of seminiferous epithelium and spermatogenic cell apoptosis in temporal lobe epilepsy (TLE) animal model treated with VPA. Fifty-six adult male rats were divided into seven groups including untreated control (Co), epilepsy (E), valproate (V), epilepsy-valproate (EV), epilepsy-ginseng (EG), valproate-ginseng (VG) and epilepsy-valproate-ginseng (EVG). Animals received daily intraperitoneal injections of valproate and ginseng for 30 days. We observed a significant decline in bilateral testes' weight and sperm counts, along with reduction in normal morphology in the EV group. Ginseng sharply improved both sperm counts and spermatozoa with normal morphology in EVG animals. Although sperm motility decreased in V and EV groups, ginseng ameliorated sperm motility in VG and EVG animals. Besides, VPA sharply decreased spermatogenesis quality and increased germ cell apoptosis. Finally, ginseng significantly diminished apoptosis in VG rats and improved spermatogenesis in both VG and EVG groups. In conclusion, ginseng treatment has shown a positive impact on spermatogenesis and sperm quality in TLE rats treated with VPA. Therefore, it may be a beneficial adjuvant along with VPA treatment in the epileptic patient., (© 2019 Blackwell Verlag GmbH.)
