Background: Gentamicin is an aminoglycoside-class antibiotic that can lead to an increase in ROS and decrease antioxidant reserves that cause destruction of testicular cells that are known to inhibit cell division in testicular germ cells and protein synthesis in the testes as well as affect the production of testosterone that affects the quality of spermatogenesis. Vitamin C as an antioxidant can counteract ROS so that testicular cells can be repaired.Methods: This study was an experimental research with post tests only control group design on 25 male rats, 2-3 aged months, weight 160-240 g. Animals were divided into 5 groups. Negative control group was placed in cage without treatment, positive control given induced gentamicin 5mg/kgbb for the first 10 days, and 3 treatment given induced gentamicin 5mg/kgbb for the first 10 days and at days 11-51 were given vitamin C at a dose of 1.6mg; 2.25mg; 4.5mg. On 52 day, all of wistar rats perform terminated for analyzed the testosterone levels were by ELISA, sperm count was calculated with then haemocytometer observed with digital microscope, morphology of spermatozoa was analyzed by eosin staining and was observed with digital microscope.Results: Results of this study showed that the average of testosteron serum on control negatif group of 3,82ng/ml, control positif 3.73ng/ml, treatment 1 is 9.52ng/ml, treatment 2 is 8.29ng/ml, and traetment 3 is 2.28ng/ml. Sperm count on control negatif 41.68 million/ml, control positif 21.06million/ml, treatment 1 is 52.92 million/ml, treatment 2 is 57.12million/ml, treatment 3 is 80.88 million/ml and sperm morphology on control negative  74.00%, control positif 46.96%, treatment 1 is 58.82%, treatment 2 is 68.68%, and treatment 3 is 78.72%.Conclusions: It is concluded that vitamin C has significant effect on increasing testosteron level and sperm quality in gentamicin-induced wistar rats.

Abstract. Two groups of six men took levo-norgestrel (250 or 500 μg daily) by mouth and testosterone oenanthate (200 mg monthly, intramuscurlarly) for six months. A three months placebo period preceded the medication which was followed by a recovery phase of 6–10 months. Two volunteers withdrew due to side effects. The five men taking the low doses of levo-norgestrel (250 μg) exhibited a reduction in sperm count, but not to azoospermia. The high dose of levo-norgestrel (500 μg) was more effective, sperm count was reduced to < 6 × 106/ ml in 3 of 5 volunteers and to < 17 × 106/ml in the remainder. s-Testosterone, LH and FSH were decreased by the treatment. The men had no toxicological side effects or changes in libido and potency. During the recovery period sperm counts, sperm morphology, s-testosterone, LH and FSH returned to normal levels.

Infertility is a worldwide problem and in almost 50% of cases infertility results from abnormality of the male partners. Apart from endocrine disorders, definitive cause and mechanism of male infertility is not clear in many cases. Recent evidence indicates that imbalance between pro-oxidant stress and antioxidant defense plays an important role in the pathogenesis of male infertility. Among the endogenous antioxidant systems, reduced glutathione (GSH) plays a significant role in the antioxidant defense of the spermatogenic epithelium, the epididymis and perhaps in the ejaculated spermatozoa. The current study was therefore designed to evaluate any association that may exist between GSH levels and male infertility. Infertile male patients (having female partners with normal fertility parameters; n=31) and age- matched healthy male fertile control subjects (n=30) were included in this study. In addition to medical history, semen analyses including semen volume, sperm count, motility and morphology were done for each subject. As a measure of antioxidant capacity erythrocyte and seminal plasma GSH concentrations were measured by Ellman's method in fertile and infertile male subjects. The infertile subjects were similar to fertile subjects in terms of age. However, semen volume and sperm count was found significantly lower (p<0.001) in infertile males compared with healthy fertile male subjects. Percentage of subjects with abnormal sperm morphology and motility were found higher in infertile group compared with fertile group. The median (range) erythrocyte GSH level did not differ between the two groups (12.62 (0.67-29.82) versus 13.93 (2.10-21.08) mg/gm Hb). However, the seminal plasma GSH level was found markedly suppressed in infertile group (1.64 (0.23-7.50)) compared with fertile group (4.26 (2.32-7.50)) mg/dl (p<0.001). In the present study seminal plasma GSH level was found markedly suppressed along with abnormal values for semen volume, sperm concentration and sperm morphology and motility in infertile subjects compared with fertile subjects. This finding indicates that low level of seminal plasma GSH level may be associated with male infertility. DOI: http://dx.doi.org/10.3329/bjmb.v4i2.13772 Bangladesh J Med Biochem 2011; 4(2): 20-25

The Difference

Red dragon fruit skin extract is used as an antioxidant to lead acetate toxicity. This study aimed to prove the difference in morphology of mice testicular spermatozoa exposed to lead acetate. Twenty-five mice were divided into 5 groups (5 mice per group). K- group was the control group without lead acetate and dragon fruit skin extract administration, K + group was treated with 8 mg/KgBW lead acetate administration for 14 days, P1 group was treated with the administration of 8 mg/KgBW lead acetate for 14 days + 250 mg/kgBW red dragon fruit skin extract for 21 days, P2 group was treated with the administration of 8 mg/KgBW lead acetate for 14 days + 500 mg/kgBW red dragon fruit skin extract for 21 days, and group P3 was a treatment group with the administration of 8 mg/KgBW lead acetate for 14 days + 1000 mg/kgBW red dragon fruit extract for 21 days. The results showed that there was significant difference (P<0.05) in normal sperm morphology among K-, K +, P1, P2, and P3. In conclusion, the administration of red dragon skin extract at a dose of 500 mg/kgBW (P2) is the optimal one which can be used as therapy to increase motility, morphology, and concentration of mice spermatozoa exposed to lead acetate.

ABSTRACTBackgroundSeveral long noncoding RNAs (lncRNAs) have been shown to function as central components of molecular machines that play fundamental roles in biology. While the number of annotated lncRNAs in mammalian genomes has greatly expanded, their functions remain largely uncharacterized. This is compounded by the fact that identifying lncRNA loci that have robust and reproducible phenotypes when mutated has been a challenge.ResultsWe previously generated a cohort of 20 lncRNA loci knockout mice. Here, we extend our initial study and provide a more detailed analysis of the highly conserved lncRNA locus, Taurine Upregulated Gene 1 (Tug1). We report that Tug1 knockout male mice are sterile with complete penetrance due to a low sperm count and abnormal sperm morphology. Having identified a lncRNA loci with a robust phenotype, we wanted to determine which, if any, potential elements contained in the Tug1 genomic region (DNA, RNA, protein, or the act of transcription) have activity. Using engineered mouse models and cell-based assays, we provide evidence that the Tug1 locus harbors three distinct regulatory activities – two noncoding and one coding: (i) a cis DNA repressor that regulates many neighboring genes, (ii) a lncRNA that can regulate genes by a trans-based function, and finally (iii) Tug1 encodes an evolutionary conserved peptide that when overexpressed impacts mitochondrial membrane potential.ConclusionsOur results reveal an essential role for the Tug1 locus in male fertility and uncover three distinct regulatory activities in the Tug1 locus, thus highlighting the complexity present at lncRNA loci.

Free radical that are released in cigarette smoke, believed to play an important role in male infertility. The free radicalproduces Reactive Oxygen Species (ROS) that is found increased in male smokers. ROS is one of the free radicalscomponent can be neutralized by vitamin C and E as an antioxidant. This study using those agents to the fifteen minuteshalf piece cigarette to expose mice and count their sperm as the fertilility parameter. The research design used was posttest-only control group with twenty mice were divided into five groups. A group of no smoke exposed was categorizedas a baseline control, the exposed groups were consisted of one group without antioxidant, one group with vitamin Ctreatment, a group of vitamin E treatment and at last the combination of vitamin C and E. All groups were treatedfor fourteen days. The results were analyzed using oneway ANOVA with p<0.05. It is obviously proven that thecombination of vitamin C and vitamin E treatment on the usual dose gave the highest sperm count compared to othergroups.

Reactive oxygen species (ROS) are physiologically involved in functions like sperm maturation, capacitation and acrosome reaction, but their excess is involved in male infertility. Antioxidants in seminal plasma (SP) are an important factor balancing physiologic and harmful ROS activities. In this study, we determined and compared the full profiles of the water- and fat-soluble antioxidants in SP and serum of 15 healthy fertile subjects (ranging between the ages of 35 and 42 years). Ejaculates were obtained after 2–5 days of sexual abstinence. After liquefaction and withdrawal of an aliquot for the sperm count, samples were centrifuged to obtain SP. Thirty min after semen donation, a venous blood sample was collected from each subject. Donors with lower SP concentrations of ascorbic acid (n = 5) or α-tocopherol (n = 5) received a 4 week oral administration of either vitamin C (100 mg/day) or vitamin E (30 mg/day). They were then re-assayed to determine the SP and serum levels of ascorbic acid and α-tocopherol. SP and serum samples were properly processed and analyzed by HPLC methods suitable to determine water (ascorbic acid, glutathione (GSH) and uric acid) and fat-soluble (all-trans-retinoic acid, all-trans-retinol, α-tocopherol, carotenoids and coenzyme Q10) antioxidants. Data demonstrate that only ascorbic acid is higher in SP than in serum (SP/serum ratio = 4.97 ± 0.88). The other water-soluble antioxidants are equally distributed in the two fluids (GSH SP/serum ratio = 1.14 ± 0.34; uric acid SP/serum ratio = 0.82 ± 0.12). All fat-soluble antioxidants are about 10 times less concentrated in SP than in serum. In donors treated with vitamin C or vitamin E, ascorbic acid and α-tocopherol significantly increased in both fluids. However, the SP/serum ratio of ascorbic acid was 4.15 ± 0.45 before and 3.27 ± 0.39 after treatment, whilst those of α-tocopherol were 0.11 ± 0.03 before and 0.10 ± 0.02 after treatment. The results of this study, by showing the peculiar composition in water- and fat-soluble antioxidants SP, indicate that it is likely that still-unknown mechanisms allow ascorbic acid accumulation in SP against a concentration gradient. SP mainly relies its defenses on water- rather than fat-soluble antioxidants and on the mechanisms ensuring their transfer from serum.

Background: The purpose of this study was to examine the effects of exposure to imatinib in the prenatal period on testis development in rats. Methods: Although all the study groups received intraperitoneal imatinib on prenatal days 1–8, no pregnancy occurred in the Imatinib-80 group. Immunohistochemical analysis, TUNEL, c-kit and PDGF staining revealed no difference between the groups in terms of positivity scoring. Results: A significant decrease was detected in total sperm counts in the Imatinib-20 group compared to the control group, but the sperm count was higher in the Imatinib-60 group than in the Imatinib-20 group. At biochemical measurements, the drug increased oxidative stress in the testis and serum in the Imatinib-20 group, but caused a decrease in tissue in the Imatinib-60 group. Thiol measurements revealed a decrease in the testis and serum in the Imatinib-60 group, while an increase in serum measurements was observed in the Imatinib-40 group. Analysis revealed no difference between the groups in terms of protamine and histone gene expression levels in testis tissue exposed to imatinib. Conclusion: Our findings show that prenatal exposure to imatinib can lead to histopathological and biochemical changes in testis tissue, but that no adverse effect occurs in nuclear maturation of germ cells during spermiogenesis.
