Proof Of Principle

BACKGROUND Semen analysis is essential for evaluating male infertility. Besides sperm concentration, other properties, such as motility and morphology, are critical indicators in assessing sperm quality. Nevertheless, rapid and complete assessment of these measures still presents considerable difficulty and involves a range of complex issues. Here we present a microfluidic device capable of quantifying a range of properties of human sperm via the resistive pulse technique (RPT). METHODS An aperture, designed as a long channel, was used to allow the quantification of various properties as sperm swam through. RESULTS The time trace of the voltage drop across the aperture during sperm passage contained a wealth of information: the sperm volume was presented by the amplitude of the induced pulse, the swim velocity was evaluated via the duration, and the beat frequency was calculated from the voltage undulation superposed on the pulse signal. The RPT measurement of swim velocity and beat frequency showed a correlation with the same observation in a microscope (R2 = 0.94 and 0.70, respectively). CONCLUSIONS The proposed proof of principle enables substantial quantification of the motion-dependent properties of sperm. Because this approach requires only a current/voltage source and data analysis, it is economically advantageous compared with optical methods for characterizing sperm motion. Furthermore, this approach may be used to characterize sperm morphology.

Introduction: Increasing infertility rate worldwide raises research to investigate plausible reason health community. To find out the characteristics of semen and spermatozoa in alcohol users and compare these characteristics with that of non-users of alcohol. Methodology: The data on alcohol use and semen analysis were obtained from case records of patients reported to the Department of Andrology & Reproductive Medicine of a tertiary care hospital for a period of one year from January 2018 to December 2018. The semen volume, sperm concentration, motility and morphology in alcohol users were compared with non-users. Results: A total of 231 patients had reported to the Department of Andrology & Reproductive Medicine during the study period. Among them 81 (35.06%) were alcohol users and 150 (64.94%) alcohol non-users. Analysis of their semen reports revealed that the difference in semen volume and sperm morphology was not found to be statistically significant, but the sperm concentration and progressive motility of spermatozoa showed significant reduction in alcohol users compared to non – users (p<0.05). Conclusion: The semen volume and sperm quality were found to be low in alcohol users. Among the spermatozoa characteristics, sperm concentration and motility were significantly reduced in alcohol users.

Abstract Introduction. Human seminal plasma contains a variety of macro and trace elements including magnesium (Mg), copper (Cu), zinc (Zn), and iron (Fe) that have essential roles in normal functioning of semen and its quality. The imbalance of these elements has been reported in several pathologic and male infertility disorders. Therefore, this study aimed to determine the levels of these elements in seminal plasma samples, their relationships with each other and their impact on sperm motility. Methods. Overall, 192 males (96 normospermic and 96 asthenospermic males) were enrolled in the study. Semen samples were collected by masturbation and computer-assisted/aided semen analysis of sperm motility was performed. The samples were centrifuged and seminal levels of Mg, Cu, Zn and Fe were measured using atomic absorption spectroscopy. Results. The levels of Zn did not differ between the two groups, while the levels of Mg, Cu, and Fe were significantly higher in normospermic males. Fe showed a positive correlation with Mg and Cu in asthenospermic group. However, a negative relationship was found between Mg and Fe levels and between Mg and sperm concentration in the normospermic group. Fe levels were higher in the normospermic group compared to the asthenospermic group. Nevertheless, increased Fe levels caused a decrease in most of sperm motility fractions. Conclusion: Elements play major roles in male fertility and directly affect sperm quality. According to the results of this study, the levels of Zn do not affect the sperm quality and motility, while Fe, Cu and Mg are decreased in males with sperm motility problems. Nevertheless, Fe levels can adversely affect sperm motility in normospermic men.

Abstract Human kallikrein-related peptidases (KLKs) are a family of proteases, the majority of which are found in seminal plasma and have been implicated in semen liquefaction. Here, we examined the clinical value of seminal KLKs in the evaluation of semen quality and differential diagnosis and etiology of abnormal liquefaction and/or viscosity. KLK1–3, 5–8, 10, 11, 13, and 14 were analyzed, using highly specific ELISA assays. Samples were categorized into four clinical groups, according to their state of liquefaction and viscosity. Data were compared between the clinical groups and in association with other parameters of sperm quality, including number of motile sperms, straight line speed, sperm concentration, volume, pH, and patient age. Seminal KLKs were found to be differentially expressed in the four clinical groups. Combination of KLK2, 3, 13, and 14 and KLK1, 2, 5, 6, 7, 8, 10, 13, and 14 showed very strong discriminatory potential for semen liquefaction and viscosity, respectively. Liquefaction state was associated with several parameters of sperm motility. Finally, KLK14 was differentially expressed in asthenospermic cases. In conclusion, the expression level of several seminal plasma KLKs correlates with liquefaction and viscosity indicators of semen quality and may aid in their differential diagnosis and etiology.

The Impact

AbstractThe impact of male aging on male fertility has only recently become of interest to the scientific community. This study aims to assess the relationship between age and fertility among a sample of men, considering the individual and pathological characteristics. In this retrospective study data of semen analysis and medical history of 1294 Italian male patients were considered. Semen analysis was performed by light microscopy and transmission electron microscopy mathematically elaborated. A generalized linear model was used to explore the influence of male age on semen quality, considering as confounders wine consumption, smoking habits, presence of varicocele, consanguinity and positive semen bacteriological analysis and urethral swab. The mean age of the participants was 36.41 ± 6.379. Male aging without impact of confounders was correlated with a decrease in sperm concentration and motility and an increased in sperm necrosis. Sperm concentration and progressive motility were negatively related to the presence of confounders as wine consumption (sperm motility), urogenital infection (sperm concentration and motility), varicocele (sperm concentration) and consanguinity (sperm motility). Urogenital infection, varicocele and consanguinity positively correlated with sperm necrosis. The most important finding was the observation of a negative effect of male aging on sperm parameters such as concentration, motility, and viability. It is possible to hypothesize age-dependent changes of testicular environment, probably related to reactive oxygen species production. The demonstration, in a large sample of patients, that aging influences sperm quality strongly motivates further research focused on the mechanisms involved in this phenomenon and its effects on offspring fitness.

Ejaculate traits in male tigers (Panthera tigris) were studied in the 1980s, but little work has been done on male tigers since then and the reproductive status of the current zoo population is not known. In order to characterise ejaculate traits in male tigers, semen was collected by electroejaculation (90 to 100 stimulations, 3 to 7V), subjected to a standard semen analysis (volume and pH and sperm concentration, motility, and morphology), and cryopreserved. To date, semen has been collected from 24 males (n=16 Amur tigers, Panthera tigris altaica, 10.3±1.1 y; n=7 Sumatran tigers, Panthera tigris sumatrae, 9.4±1.3 y; n=1 Malayan tiger, Panthera tigris jacksoni, 6 y), maintained at 18 USA institutions. Ejaculates (4.7±0.6 mL; pH=8.4±0.1) contained 240.3±54.9×106 spermatozoa, which yielded 357 straws of cryopreserved spermatozoa that were used to establish a Tiger Genome Resource Bank. The majority of the spermatozoa were motile (69.2±4.6%), but the proportion of spermatozoa exhibiting normal morphology was very low (18.7±3.3%) and similar between both Amur (20.0±4.8%) and Sumatran (16.3±5.2%) males, with the majority of abnormalities affecting the midpiece (retained cytoplasmic droplets, bent midpieces, or both). Previous studies of male tigers that utilised comparable anaesthesia regimens and collection techniques recovered similar quantities of semen (5 to 10mL), but the proportions of normal spermatozoa in those studies (&gt;65%) were very high (Wildt et al. 1988 Biol. Reprod. 38, 245; Byers et al. 1990 J. Reprod. Fert. 90, 119). Proportions of normal spermatozoa in the current study more closely resemble those reported for the teratospermic (&lt;40% normal spermatozoa) clouded leopard (Neofelis nebulosa, 18.5% normal spermatozoa, Pukazhenthi et al. 2006 Theriogenology 66, 1790) and cheetah (Acinonyx jubatus, 18.4% normal spermatozoa, Crosier et al. 2007 Reprod. Fertil. Dev. 19, 370), as well as the South China tiger (Panthera tigris amoyensis, 27% normal spermatozoa). The number of spermatozoa per ejaculate was also decreased in Amur tigers (190.1±67.7×106) compared to Sumatran tigers in the current study (362.9±99.5×106) and earlier studies of other Amur tigers (&gt;500×106). The reasons for this apparent decline in sperm quality are unclear, but reduced proportions of normal spermatozoa have been associated with reduced heterozygosity in small, isolated populations of felids (Florida panthers, South China tigers) or species that have been through a genetic bottleneck (cheetahs). Semen collections and evaluations will continue in order to determine if trends for compromised sperm quality are representative of the current SSP population(s) or an artifact of our reduced sample size. Additional studies investigating possible environmental, genetic, or nutritional influences on sperm morphology are also warranted.

Acetyl Cysteine

Male infertility is an important factor accounting for 40-50% of infertility cases that may be due to disturbance in one of the parameters as concentration, motility and morphology observed in one or two semen analysis with an interval of 1 and 4 weeks. COVID-19 may affect male fertility through virus division, cytotoxic effects on testicular tissue and immunopathological effect. N-acetyl cysteine (NAC) improved sperm concentration and acrosome reaction while reducing reactive oxygen species (ROS) and oxidation of sperm DNA. This interventional study was conducted on 200 men who were referred to private infertility clinics for female factor (their previous semen analysis was normal) and got COVID-19 infection in the last 3 months showing an impairment of the latest semen analysis due to COVID. Men were placed in two groups of control (n = 100) and intervention (NAC consumption). Subjects who got COVID-19 infection had a significant impairment of sperm quality (sperm concentration, sperm motility, and normal sperm morphology) compared to their semen analysis evaluated before the COVID-19 infection. NAC consumption significantly improved sperm total motility, sperm morphology and sperm concentration. COVID-19 infection has a negative effect on sperm parameters. NAC supplementation may have positive effect on sperm parameters.

Helicobacter pylori(HP) infection, particularly when caused by strains expressing CagA, may be considered a concomitant cause of male and female reduced fertility. This study explored, in 87 HP-infected males, the relationship between infection by CagA-positive HP strains and sperm parameters. HP infection and CagA status were determined by ELISA and Western blotting; semen analysis was performed following WHO guidelines. The amino acid sequence of human enzymes involved in glycolysis and oxidative metabolism were “blasted” with peptides expressed by HP J99. Thirty-seven patients (42.5%) were seropositive for CagA. Sperm motility (18% versus 32%; ), sperm vitality (35% versus 48%; ) and the percentage of sperm with normal forms (18% versus 22%; ) in the CagA-positive group were significantly reduced versus those in the CagA-negative group. All the considered enzymes showed partial linear homology with HP peptides, but four enzymes aligned with four different segments of the samecagisland protein. We hypothesize a relationship between infection by strains expressing CagA and decreased sperm quality. Potentially increased systemic levels of inflammatory cytokines that occur in infection by CagA-positive strains and autoimmune phenomena that involve molecular mimicry could explain the pathogenetic mechanism of alterations observed.

Leukocyte Counts

Infertility is one of the most common male reproductive health problems. Male infertility is the inability of a male to result pregnancy in a fertile female in one year of non-contracepting sexual intercourse. Male with poor sperm quality are more susceptible to infertility. One of the cause of infertility in men is disruption of spermatozoa motility. Imperfect motility will reduce the quality of spermatozoa and the probability of conception. One cause of decreased motility is inflammation of the male reproductive tract. Inflammation that occurs will increase the recruitment of leukocytes in the reproductive tract and increase the production of reactive oxygen species (ROS) so it can interfere the process of sperm formation and maturation. The purpose of this study was to determine the relationship between leukocyte counts and spermatozoa motility. The number of leukocytes and the percentage of spermatozoa motility were obtained from semen analysis as secondary data. The research design used was cross-sectional. The number of samples in this study were 66 respondents who met the inclusion criteria.The results of the study showed a significant inverse relationship (negative correlation) (p = 0.007, r = -0.328) between the number of leukocytes and spermatozoa motility, which means  if the number of semen leukocytes increases, the percentage of spermatozoa motility will decrease. Keywords: inflammation; leukocyte counts; spermatozoa motility ABSTRAKInfertilitas merupakan salah satu masalah kesehatan reproduksi pria yang sering dijumpai. Infertilitas pada pria adalah ketidakmampuan seorang pria untuk menyebabkan kehamilan pada seorang wanita fertil setelah satu tahun hubungan seksual tanpa alat kontrasepsi. Pria dengan kualitas sperma yang kurang baik lebih rentan mengalami infertilitas. Salah satu penyebab infertilitas pada pria adalah gangguan pada motilitas spermatozoa. Motilitas yang kurang sempurna akan menyebabkan penurunan kualitas spermatozoa dan penurunan probabilitas terjadinya pembuahan. Salah satu penyebab penurunan motilitas adalah inflamasi pada saluran reproduksi pria. Inflamasi yang terjadi akan meningkatkan rekruitmen leukosit pada saluran  reproduksi pria dan meningkatkan produksi reactive oxygen species (ROS) yang bersifat toksik bagi spermatozoa sehingga dapat mengganggu proses pembentukan dan pematangan spermatozoa. Tujuan penelitian ini adalah untuk mengetahui hubungan antara jumlah leukosit dengan motilitas spermatozoa. Jumlah leukosit dan persentase motilitas spermatozoa didapatkan dari data sekunder, yaitu data hasil analisis semen. Desain penelitian yang digunakan adalah potong lintang (cross-sectional). Jumlah sampel dalam penelitian ini sebanyak 81 pasien yang memenuhi kriteria inklusi. Hasil dari penelitian menunjukkan terdapat hubungan terbalik (korelasi negatif) yang bermakna dengan kekuatan korelasi sangat lemah (p = 0.007, r = -0.328) antara jumlah leukosit dengan motilitas spermatozoa, yang berarti jika jumlah leukosit semen semakin meningkat, maka persentase motilitas spermatozoa akan semakin rendah.
