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.

AbstractIn the seminal plasma (n = 118) and serum (n = 90) clusterin (CLU) the fucosylation and the expression of selected fucosyltransferases (FUTs) were analyzed. Samples from infertile men were divided into groups based on the results of the standard semen analysis: normozoospermic (N), teratozoospermic (T), asthenoteratozoospermic (AT) and oligoasthenoteratozoospermic (OAT). The CLU fucosylation was analyzed using lectin-ELISAs with biotinylated lectins specific to α1,3-, α1,2-linked antennary fucose, and α1,6-linked core fucose (LTA, UEA, and LCA, respectively). The concentrations of FUT3 and FUT4, reflecting the expression of Le oligosaccharide structures, were measured using ELISA tests. The differences in serum CLU and FUT4 concentrations, and in the expression of core fucose and antennary fucose α1,2-linked in CLU glycans between the N group and other groups examined suggest that the disturbances in sperm count, motility, and morphology are not the only cause of male infertility. Lack of similarities between levels of examined parameters in blood serum and seminal plasma may suggest the differences in mechanisms leading to glycoproteins glycosylation. It confirmed the observed differences in concentrations of seminal plasma CLU, FUT3, and FUT4 between the OAT group and N, T, AT groups, indicating that decreased sperm count may be related to these parameters expression. The serum CLU concentrations and expression of core fucose and fucose α1,2-linked in CLU, seem to be good markers differentiating normozoospermic men from those with abnormal sperm parameters, which was not observed for seminal plasma.

A Prospective Study

Introduction: Approximately 15% of couples are infertile. Male infertility plays an important role in about half of these couples. This study has been done to determine whether sperm morphology and motility do really affect sperm count or spermatogenesis and at the same time causes a problem with fertility.Objectives: The objective of this study was to evaluate a male’s inability to cause pregnancy in a fertile female.Materials and Methods: This is a prospective study of 100 diagnosed infertile and subfertile couples in the age group of 23-58 yrs old male. They were selected from 01 March 2013 to 28 Feb 2014 undergoing treatment for infertility in Dhaka CMH. On the basis of sperm count the cases were grouped as follows: Normozoospermia, oligozoospermia & Azoospermia. Semen analysis was done in all the cases and the results were described with arithmetic mean and standard deviation.Results: Normozoospermia: Mean and SD of sperm count, sperm abnormality, sperm motility are 65.98± 5.05, 24.44±1.57 and 45.5±2.94 respectively; Oligozoospermia: Mean and SD of sperm count, sperm abnormality, sperm motility are 7.74±1.23, 41.1±3.78, 14.54±2.77 respectively; Azoospermia: Mean and SD of sperm count, sperm abnormality, sperm motility are absent.Conclusion: Here data statistically showed person with normozoospermia having good sperm morphology and motility than oligozoospermia and azoospermic subjects thereby causing male infertility which is responsible for hindrance in achieving pregnancy clinically.Journal of Armed Forces Medical College Bangladesh Vol.11(1) 2015: 50-53

Male Reproductive Health

Male reproductive health depends upon the normal structures and functions of Shukrava srotas. Shukra is composed of both sperm and semen and considered one of the important factors for fertilization. It is stated as Phalavat shukra. Preceptors of Ayurveda have described eight types of Shukra dosha and their treatments. Low sperm count, decrease sperm motility, abnormal sperm morphology, ejaculatory problems, sexual dysfunctions, environmental exposures (radiation, pollution, and stress etc), lifestyle habits (smoking, alcohol, recreational drugs etc), varicocele, hormonal imbalances, DNA damage, and reactive oxygen species (ROS) etc are causative factors for Male infertility. Thousands of years back, ancient system of medicine has mentioned the word Purusha vandya (male infertility) and different pharmacological activities, medicinal formulas, therapies to treat sperm disorders, semen impairments, and sexual dysfunctions. Vajeekarana is one of the special branches of Astanga Ayurveda which maintains the fertility and management of male infertility. Shukrala, Shukra janana, Shukra shodhana, Shukra rechaka, Shukra pravataka and Shukra sthambhaka etc., are the pharmacological activities mentioned to treat Shukradoshas. Shukrala karma mainly composed of Shukra vrudhikara and Shukra srutikara means which enhances the Shukra (semen and sperm) quantitatively and qualitatively and facilitates its ejaculation. Therefore, an attempt has been made to establish the concept of Shukrala karma and its therapeutic applicability in the management of male infertility.

Background. Semen analysis is the cornerstone in the evaluation of male (in)fertility. However, there are men with normal semen tests but with impaired fertilizing ability, as well as fertile men with poor sperm characteristics. Thus, there is rising interest to find novel parameters that will help to predict and define the functional capacity of spermatozoa.Methods. We examined whether there is a correlation between semen parameters (count, progressive motility, and morphology) and protein expression/activity of antioxidative defense enzymes in seminal plasma from 10 normospermic subjects.Results. Sperm progressive motility was in positive correlation with seminal plasma protein expression of both superoxide dismutase (SOD) isoforms (MnSOD and CuZnSOD) and catalase. Also, positive correlation was observed between sperm count and MnSOD protein expression, as well as between sperm morphology and protein expression of catalase in seminal plasma. In contrast, protein expression of glutathione peroxidase was not in correlation with any sperm parameter, while its activity negatively correlated with sperm morphology and motility.Conclusions. These data suggest that evaluation of protein expression of antioxidative defense enzymes in seminal plasma might be of importance in the evaluation of male fertility status and that could be used as an additional biomarker along with classic semen analysis in assessment of semen quality.

Background: Semen analysis is used to evaluate male fertility. The aim of this study was to compare the results of semen analysis using manual method and automated sperm analyzer.Materials and Methods: This was a comparative study of 50 cases of semen analysis done in the Department of Pathology at the B.P. Koirala Institute of Health Sciences from March 2009 to March 2010. The automated sperm analyzer did not show the WHO parameters of patients who had functional sperm count (FSC) less than five hundred thousand (500,000). Semen analysis of each of the case included in the study was done by manual and automated method (using SQAII-P analyzer).Results: Out of 31 patients, the mean age of the patients was 28.56 years with youngest patient of 20 years and eldest of 45 year. Sensitivity and specificity was 100% in analysis of sperm concentration by both the methods. Sperm motility analysis showed 100% sensitivity and 81.81% specificity. Sperm morphology analysis showed 100% sensitivity and 34.48% specificity.Conclusion: It was observed that the automated method is much quicker and precise than the conventional, manual method for semen analysis.

Background: The aim of this study was to compare consequences in single and triple testicular biopsy by biopty gun in pubertal rats using histological and immunohistochemical analysis. Methods: Thirty-two Sprague-Dawley male rats were used as the experimental model. The rats were randomly divided into three study groups. The rats from the first group (n = 12) received a single-biopsy of upper pole of the left testis, while the rats from the second group (n = 10) received triple-biopsy of upper and lower poles and lateral surface of left testis. The third group (n = 10) was a control group. On the eightieth day after the biopsy in all rats bilateral orchiectomy and funiculectomy were performed to obtain testicular tissue and sperm for analysis. The consequences of the puncture were observed by pathohistology, immunohistochemistry and semen analysis. Results: The results of the study showed lower percentage of sperm count (14.5 mill/mL vs. 16 mill/mL, p = 0.130), sperm motility (24.6% vs. 32.7%, p > 0.05), abnormal sperm (30% vs. 27%, p > 0.05), atrophic tubules (21% vs. 6%, p < 0.001), volume (1.7 mL vs. 2.28 mL, p < 0.01) and apoptotic index (1.56 vs. 1.19, p = 0.650) in the testes with a triple-biopsy compared to the testes with a single-biopsy. Semen analysis showed a borderline significant difference between the group with triple-biopsy where sperm count was lower than it in the control group (14.5 mill/mL vs. 17.5 mill/mL, p = 0.05). A single-biopsy has little effect on the testis, especially on overall fertility. A triple-biopsy showed higher degree of the testicular damage but without a significant impact on overall fertility. Semen analysis showed that single- and triple-biopsies did not have a significant effect on sperm count, motility and morphology. Conclusion: Biopty gun procedure is a cheap, simple and reliable method for testicular biopsy in rats without a significant effect on sperm count, motility and morphology.

Abstract Background Varicocele is an abnormally dilated pampiniform plexus of the veins within the spermatic cord and is considered the most common correctable cause of male factor infertility. Many approaches are described for treatment either surgical (tradition inguinal, subinguinal, and laparoscopic) or non-surgical percutaneous embolization. During the period from August 2017 to December 2018, we prospectively analyzed the preoperative and post-operative alteration of semen parameters (at 3 and 9 months) of the data collected from 63 patients with clinically evident varicocele referred to our tertiary hospital. Patients were divided into two groups: group 1, thirty-three patients who underwent subinguinal microsurgical ligation, and group 2, thirty patients who underwent percutaneous embolization. Results Sixty-three patients enrolled in this study were divided in two groups: group 1, patients who underwent surgery, and group 2, patients who underwent embolization; the mean age is 24.6 ± 1.27 years in group 1 and 23.7 ± 2 years in group 2; there was no statistically significant difference between the two groups as regards BMI, diabetes, hypertension, and smoking. Bilaterality was present in 15.2% of group 1 patients and 10% in group 2 patients (P value 0.06). Most of the patients were classified as grades 2 and 3 with no statistical significance regarding severity of the disease. Preoperative semen parameters for patients including sperm count, motility, and abnormal forms showed no statistically significant difference between the two groups. Post-intervention semen analysis was done twice during follow-up after 3 months and 9 months from the date of intervention. After 3 months, the semen parameters were improved in both groups in spite of the higher sperm count in group 2 but with no statistical significance. After 9 months follow-up, semen analysis showed persistent increase in sperm mobility in group 1 patients in comparison to group 2 patients. Both groups had better improvement in count of normal form with no statistical significant change. Conclusion Improvement of semen parameters while treating primary varicocele by either subinguinal microsurgery approach or percutaneous embolization shows equivalent outcomes.

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
