Maintenance of motility in mouse sperm permeabilized with streptolysin O. (1/2575)

One approach to studying the mechanisms governing sperm motility is to permeabilize sperm and examine the regulation of motility by manipulating the intracellular milieu of the cell. The most common method of sperm permeabilization, detergent treatment, has the disadvantage that the membranes and many proteins are extracted from the cell. To avoid this problem, we have developed a method that uses streptolysin O to create stable pores within the plasma membrane while leaving internal membranes intact. Sperm were permeabilized, preincubated, and then treated with 0.6 U/ml of streptolysin O. Permeabilization was assessed by fluorescent dye technologies and endogenous protein phosphorylation using exogenously added [gamma-32P]ATP. Streptolysin O-induced permeabilization rendered the sperm immotile, and the effect was Ca2+-dependent. When the cells were treated simultaneously with a medium containing ATP, streptolysin O-treated sperm maintained flagellar movement. These results demonstrate that the streptolysin O permeabilization model system is a useful experimental method for studying the mechanisms that regulate sperm motility since it allows the flagellar apparatus to be exposed to various exogenously added molecules.  (+info)

A sialoglycoprotein, gp20, of the human capacitated sperm surface is a homologue of the leukocyte CD52 antigen: analysis of the effect of anti-CD52 monoclonal antibody (CAMPATH-1) on capacitated spermatozoa. (2/2575)

In this study we performed N-terminal sequence analysis of gp20, a 20 kDa sialoglycoprotein on the human sperm surface previously identified by radiolabelling of the sialic acid residues of sperm surface. We found 100% identity with the N-terminus of CD52, an antigen expressed on almost all human leukocytes. We also show that, like CD52, gp20 behaves as a glycosylphosphatidylinositol (GPI)-anchored protein and that anti-gp20 antiserum reacts with an antigen on leukocytes of the same molecular weight as CD52. Using CAMPATH-1, the monoclonal antibody against CD52, in fluorescent staining of capacitated spermatozoa, Western blot analysis and the zona-free hamster egg penetration test, we found that the effect of this antibody was different from that of our anti-gp20. Western blot analysis revealed a well-defined 20 kDa band with anti-gp20, whereas a 14-20 kDa band was detected with CAMPATH-1. Anti-gp20 stained the equatorial region of the sperm head, whereas CAMPATH-1 stained the tail in immunofluorescence analysis of capacitated spermatozoa. A dose-dependent inhibitory effect was seen with CAMPATH-1, similar to that previously detected with anti-gp20, in a zona-free hamster egg penetration test. However, with CAMPATH-1 agglutination of motile spermatozoa was detected, and this was not present with anti-gp20. This suggests that the epitopes recognized by the two antibodies are different.  (+info)

Binding of annexin V to plasma membranes of human spermatozoa: a rapid assay for detection of membrane changes after cryostorage. (3/2575)

When the cell membrane is disturbed, phospholipid phosphatidylserine (PS) is translocated from the inner to the outer leaflet of the plasma membrane. This is one of the earliest signs of apoptosis and can be monitored by the calcium-dependent binding of annexin V. Therefore, annexin V-binding, in conjunction with flow cytometry, was used to evaluate the integrity of the sperm plasma membrane after different cryostorage protocols: i.e. 10% (v/v) glycerol; sperm maintenance medium (MM); freezing medium TEST yolk buffer (TYB); or cryostorage without protection (cryoshock). Using a combination of two fluorescent dyes, annexin V and propidium iodide (PI), led to three groups of spermatozoa being identified: (i) viable spermatozoa (annexin V-negative and PI-negative); (ii) dead spermatozoa (annexin V-positive and PI-positive); and (iii) cells with impaired but integer plasma membrane (annexin V-positive and PI-negative). The percentage of vital annexin V-negative spermatozoa increased significantly (P < 0.05) from spermatozoa treated by cryoshock (15.0+/-1.2%) to spermatozoa cryopreserved by TYB (26.6+/-2.2%) via cryopreservation by 10% (v/v) glycerol (19.9+/-1.6%) and by MM (22.2 1.8%) and was associated with the percentage of motile spermatozoa (17.6+/-3.4% by glycerol; 19.6+/-3.7% by MM and 22.6+/-3.9% by TYB; P = 0.0001). Of the spermatozoa, 12-22% were annexin V-positive even though they did not bind to PI, indicating viability before as well as after cryostorage. The percentage of vital annexin V-positive spermatozoa was significantly correlated with different sperm motility parameters (velocity straight linear, r = 0.601, P = 0.018; percentage of linearly motile spermatozoa: r = 0.549, P = 0.034). We, therefore, concluded that annexin V-binding is more sensitive in detecting a deterioration of membrane functions than PI staining, and that a considerable percentage of spermatozoa might have dysfunctional plasma membranes besides dead or moribund cells. Of the cryopreservation protocols tested, TYB yielded the most viable spermatozoa. Therefore, we advocate the use of the annexin V-binding assay for the evaluation of the quality and integrity of spermatozoa.  (+info)

Effects of taurine on the motility and intracellular free Ca2+ concentration of fowl spermatozoa in vitro. (4/2575)

The effects of taurine on the motility and intracellular free Ca2+ concentration of fowl spermatozoa were investigated in vitro. The addition of taurine, within the range of 0-5 mmol l(-1), did not appreciably affect the motility of intact fowl spermatozoa. Motility remained almost negligible at 40 degrees C, while vigorous movement was observed at 25 degrees C. Even with the addition of Ca2+ before the addition of taurine, neither stimulation nor inhibition of motility was observed compared with the control (no addition of taurine). Similar results were obtained by the addition of taurine and calyculin A, a specific inhibitor of protein phosphatases. There were no changes in intracellular free Ca2+ concentrations, measured by a fluorescent Ca2+ indicator, fura-2, in taurine-treated spermatozoa. These results suggest that taurine is not involved in the regulation of fowl sperm motility and metabolism by intracellular Ca2+ mobilization in vitro.  (+info)

Occurrence of prostasome-like membrane vesicles in equine seminal plasma. (5/2575)

Equine seminal plasma was shown to contain membrane vesicles that are similar to the well characterized prostasomes in human seminal plasma. Determination of nucleoside and nucleotide concentrations of these particles have shown that ATP, ADP and adenosine are the main components of the nucleotidic pool. 5' nucleotidase, endopeptidase and dipeptidyl peptidase i.v. activities have been found on the surface of the particles. The interaction between these prostasome-like vesicles and spermatozoa was demonstrated by electron micrograph scans which revealed the steps of a fusion-like process leading to mixing of the membranes. In addition, endopeptidase activity, a marker enzyme of these seminal vesicles that is normally absent from equine spermatozoa, was shown to be acquired by these cells after interaction with the vesicles. The addition of these vesicles to equine spermatozoa resulted in the modification of adenylate catabolism. Therefore, a role in stabilizing the energy charge of the spermatozoa thus allowing longer viability is proposed for these organelles.  (+info)

Sperm abnormalities and histopathological changes in the testes in Crj:CD(SD)IGS rats. (6/2575)

In this study, morphological examination and computer-assisted sperm analysis (CASA) of epididymal spermatozoa in non-treated Crj:CD(SD)IGS rats were performed, and the relationship between the data obtained and the retention of step 19 spermatids in Stage IX to XI seminiferous tubules was examined. Retention of step 19 spermatids in Stage IX to XI seminiferous tubules was observed in all 50 untreated males, and the incidence ranged from 3.3% to 100%. Eighteen animals showed a high incidence of retention (74.7 +/- 14.2%, HIR for short), and the others showed a low incidence (24.9 +/- 11.0%, LIR for short). Although the incidence of retention in Stage X and XI seminiferous tubules was very low in LIR males, it was high in HIR males (1.8 +/- 3.0% vs 58.6 +/- 23.2%). Morphological abnormalities of sperms in the caudal region of the epididymis, mainly amorphous head and no head, were more frequently observed in HIR males than in LIR males (36.2 +/- 28.5% vs 1.8 +/- 1.2%). Sperm analysis also revealed some differences between HIR and LIR males: sperm motility in HIR males was severely lower than that in LIR males, and sperm velocity, beat/cross frequency and amplitude of lateral head displacement in HIR males were lower than the corresponding values in LIR males. In summation, retention of step 19 spermatids frequently occurred in the non-treated Crj:CD(SD)IGS males, and a relationship between the retention of these spermatids and sperm abnormalities, such as morphologically abnormal sperms, low motility and other items revealed by sperm analysis (CASA), was suggested.  (+info)

Inhibition of human sperm motility by specific herbs used in alternative medicine. (7/2575)

PURPOSE: Our purpose was to analyze sperm motility parameters in the presence of herbs. METHODS: Washed sperm were incubated in either saw-palmetto (Serenoa repens, Permixon Sabal serrulatum), echinacea purpura, ginkgo biloba, St. John's wort (Hypericum perforatum), or control medium. Parameters were measured on a Hamilton-Thorn analyzer after 1, 4, 24, and 48 hr at 37 degrees C. RESULTS: Sperm motility was inhibited at the high concentration (0.6 mg/mL) of St. John's wort. Curvilinear velocities and beat cross frequencies also decreased, but not hyperactivation. High-concentration saw-palmetto, echinacea, or gikgo inhibited motility at 24 and 48 hr. CONCLUSIONS: A potent inhibition of sperm motility was seen in St. John's wort unrelated to changes in pH. Furthermore, sperm viability was compromised in St. John's wort, suggesting a spermicidal effect. Metabolic changes were observed in saw-palmetto-treated sperm. High-concentration echinacea purpura interfered with sperm enzymes. Ginkgo did not have an antioxidant effect on sperm motility.  (+info)

Hyperactivated motility of human spermatozoa: a review of physiological function and application in assisted reproduction. (8/2575)

Hyperactivated motility is a specific movement pattern which has been recognized in mammalian spermatozoa for over 25 years. During this time, it has been established that hyperactivation is part of the complex process of sperm capacitation, which is necessary before fertilization can occur. The recent introduction of computed sperm motility analysis has allowed detailed studies of sperm movement characteristics to be undertaken, and evidence is accumulating that hyperactivated motility may correlate with fertility. In this review, the physiological consequences of hyperactivated motility, methods of measurement and their application in assisted reproduction are discussed.  (+info)

Motility is an essential characteristic of all fl agellated spermatozoa and assessment of this parameter is one criterion for most semen or sperm evaluations. Computer-aided sperm analysis (CASA) can be used to measure sperm motility more objectively and accurately than manual methods, provided that analysis techniques are standardized. Previous studies have shown that evaluation of sperm subpopulations is more important than analyzing the total motile sperm population alone. We developed a quantitative method to determine cut-off values for swimming speed to identify three sperm subpopulations. We used the Sperm Class Analyzer ® (SCA) CASA system to assess the total percentage of motile spermatozoa in a sperm preparation as well as the percentages of rapid, medium and slow swimming spermatozoa for six mammalian species. Curvilinear velocity (VCL) cut-off values were adjusted manually for each species to include 80% rapid, 15% medium and 5% slow swimming spermatozoa. Our results indicate that ...
MAPEKA, M.H.; LEHLOENYA, K.C. and NEDAMBALE, T.L.. Comparison of different extenders and storage temperature on the sperm motility characteristics of Kolbroek pig semen. S. Afr. j. anim. sci. [online]. 2012, vol.42, n.5, pp.530-534. ISSN 2221-4062.. Maintaining a successful pig artificial insemination programme depends on a number of factors, including evaluation of semen characteristics. This study compared the efficacy of different extenders on the sperm motility of Kolbroek semen during short term storage at 4 °C and 25 °C. Semen was collected from Kolbroek boars using the gloved hand technique and transported to the laboratory for evaluation. Semen was pooled and randomly allocated to four groups and diluted at a ratio of 1:1 (v/v) with Beltsville thawing solution (BTS), Kobidil+, egg yolk citrate (EYC) and non-extended semen (Control). Each extender had two similar semen samples, making a total of eight samples. Extended and non-extended semen were stored at 4 °C and the other samples at ...
Nitric oxide (NO), a modulator of several physiological processes, is involved in different human sperm functions. We have investigated whether NO may stimulate the motility of human spermatozoa via activation of the soluble guanylate cyclase (sGC)/cGMP pathway. Sperm samples obtained by masturbation from 70 normozoospermic patients were processed by the swim-up technique. The kinetic parameters of the motile sperm-rich fractions were assessed by computer-assisted sperm analysis. After a 30-90â min incubation, the NO donor S-nitrosoglutathione (GSNO) exerted a significant enhancing effect on progressive motility (77, 78, and 78% vs 66, 65, and 62% of the control at the corresponding time), straight linear velocity (44, 49, and 48â µm/s vs 34, 35, and 35.5â µm/s), curvilinear velocity (81, 83, and 84â µm/s vs 68â µm/s), and average path velocity (52, 57, and 54â µm/s vs 40, 42, and 42â µm/s) at 5â µM but not at lower concentrations, and in parallel increased the synthesis of cGMP. ...
Semen samples were collected from four rams and pooled, diluted with Tris-egg yolk extender without RJ (control) or supplemented with different concentrations of RJ (0, 0.5, 1, 1.5 and 2%), at a final concentration of 200 × 106 sperm/mL. Sperm viability, kinematics and membrane functionality were determined by nigrosin-eosin staining, computer-assisted sperm analysis (CASA), and by using the hypo-osmotic swelling test (HOST), respectively. Additionally, the oxidative and nitrosative status were evaluated after the RJ supplementation. The RJ supplementation resulted in a significant (P , 0.05) increase of sperm viability with the highest increase at 1% RJ concentration for 120 h. A significant protective effect of RJ on sperm membrane functionality was obtained at lower concentrations (0.5 and 1%) and in all incubated time points. The most prominent protective effect of RJ on sperm motility parameters was found on the progressive velocity (VSL) as after 72 h storage, no significant reduction was ...

Nitric oxide (NO) has been shown to be important in sperm function, and the concentration of NO appears to determine these effects. Studies have demonstrated both positive and negative effects of NO on sperm function, but have not been able to provide a clear link between NO concentration and the extent of exposure to NO. To study the relationship between nitric oxide and sperm capacitation in vitro, and to provide a theoretical basis for the use of NO-related preparations in improving sperm motility for in vitro fertilization, we investigated the effects of NO concentration and time duration at these concentrations on in vitro sperm capacitation in both normal and abnormal sperm groups. We manipulated NO concentrations and the time duration of these concentrations using sodium nitroprusside (an NO donor) and NG-monomethyl-L-argenine (an NO synthase inhibitor). Compared to the normal sperm group, the abnormal sperm group had a longer basal time to reach the appropriate concentration of NO (p | 0.001),
CATSPER is a family of sperm-specific calcium channels activated by P in human spermatozoa (Lishko et al. 2011, Strunker et al. 2011). KO mice for CATSPER are infertile due to severe defects in sperm motility.. We studied the involvement of CATSPER in human sperm motility and P responsiveness.. Western blot analysis with an anti-CATSPER1 antibody demonstrated the presence of three major bands corresponding to CATSPER1, 2 and 3 4. By immunoflorescence we observed that channels are mainly located in the principal piece of the tail. Higher levels of CATSPER were found by flow cytometry analysis in swim up selected spermatozoa respect to unselected (50.9±16.6 vs 23.4±10.7, n=6, P=0.01). To investigate the role of CATSPER channels in human sperm motility, we evaluated the effects of the specific inhibitor NNC55-0396 (10 and 20 μM) and the non specific inhibitor mibefradil (30 and 40 μM) on swim up selected spermatozoa (n=13) by CASA system. Both compounds significantly inhibited several ...

In the past, I received a boatload of spam comments indicating that due to the light that embryos are exposed to during the process of IVF, they are significantly harmed. I must say that I didnt read these thoroughly (and assume most were from the same person or organization, since they seemed to originate from India) and wasnt really worried about it since my three IVF children appear to be perfectly normal... What brought back this memory was an article I read in this mornings Haaretz about the ability of visible light waves to significantly improve sperm motility.

CASA is an automated system for sperm analysis which makes use of a software for the evaluation of sperm concentration, motility and morphology. The main advantage of CASA is that it eliminates the subjectivity associated with the human factor in manual semen analysis, thereby allowing for better standardization of the procedure. Furthermore, the software counts the spermatozoa more accurately, can calculate and record their exact speed and movement trajectory as well as the dimensions of their heads, midpieces and tails for more accurate morphology evaluation. Using computer aided sperm analysis also allows better visualization of the results, which aids patient understanding.. ...
The present study evaluated the effects of exposing liquid-stored boar semen to different red light LED regimens on sperm quality and reproductive performance. Of all of the tested photo-stimulation procedures, the best pattern consisted of 10 min light, 10 min rest and 10 min of further light (10-10-10 pattern). This pattern induced an intense and transient increase in the majority of motility parameters, without modifying sperm viability and acrosome integrity. While incubating non-photo-stimulated sperm at 37 °C for 90 min decreased all sperm quality parameters, this reduction was prevented when the previously-described light procedure was applied. This effect was concomitant with an increase in the percentage of sperm with high mitochondrial membrane potential. When sperm were subjected to in vitro capacitation, photo-stimulation also increased the percentage of sperm with capacitation-like changes in membrane structure. On the other hand, treating commercial semen doses intended for ...

Analysis of sperm characteristics is typically performed for animal husbandry, to analyze and resolve human conception difficulties, and to examine the result of a vasectomy operation. Initially, sperm samples were manually examined under a microscope by lab technicians to determine an individuals sperm count, sperm motility, and sperm morphology. Computer Aided Sperm Analysis (CASA) systems were originally proposed in the 1980s to reduce labor and time cost from manual analysis. Modern CASA systems typically consist of a light microscope platform used to digitally capture images of processed sperm samples, which are sent to an attached computer for image processing to determine sperm characteristics of interest using custom-developed software. These systems, albeit accurate, can only image a subsample of the sperm inside the sample due to the reduced field-of-view from the microscopes high magnification optics. They are fairly large, has a low throughput, and due to being reliant on ...
The principal aim of this study was to determine whether subjective estimations of sperm velocity in our laboratory could readily be translated into objective figures.
Abstract: Motility initiation in crawling cells requires transformation of a symmetric state into a polarized state. In contrast, motility arrest is associated with re-symmetrization of the internal configuration of a cell. Experiments on keratocytes suggest that polarization is triggered by the increased contractility of motor proteins but the conditions of re-symmetrization remain unknown. In this paper we show that if adhesion with the extra-cellular substrate is sufficiently low, the progressive intensification of motor-induced contraction may be responsible for both transitions: from static (symmetric) to motile (polarized) at a lower contractility threshold and from motile (polarized) back to static (symmetric) at a higher contractility threshold. Our model of lamellipodial cell motility is based on a 1D projection of the complex intra-cellular dynamics on the direction of locomotion. In the interest of analytical transparency we also neglect active protrusion and view adhesion as passive. ...

Biology of Reproduction contains original scientific research on a broad range of topics in the field of reproductive biology, as well as minireviews.
Investigators have used the reconstituted system to identify specific proteins that regulate the assembly of MSP. One critical component from the vesicle fraction is a 48kDa integral membrane protein with the unwieldy name major sperm protein polymerization organizing protein or, more simply, MPOP (LeClaire et al., 2003). Phosphorylation of tyrosine residues appears to regulate the activity of MPOP. Immunolabeling of spermatozoa with anti-MPOP antibodies indicates that the protein is evenly distributed throughout the sperm plasma membrane, but anti-phosphotyrosine labeling of the membrane is restricted to the leading edge of the pseudopod. Purified phosphorylated MPOP, when combined with cytosol and ATP, is sufficient to promote MSP filament assembly in the absence of other vesicle components. Intriguingly, lowering the pH blocks both tyrosine phosphorylation of MPOP and the in vivo assembly of MSP in a similar manner. This obs ervation suggests an appealing mechanism for the regulation of ...

Yes, the straight line is a best fit line to the data. When trying to determine the order of a reaction from the data, you need to plot the data and see what operation you need to do to make the best fit curve be a straight line instead of an exponential decay or other nonlinear graph. For example, if plotting the experimental data on a ln[A] vs time graph gives a straight best fit line, then the reaction is first order. If plotting the data on a 1/[A] vs time graph gives a straight line, then the reaction is second order. You may need to plot it multiple times to find the correct one. I hope this helps ...

Low sperm motility is not a big health issue. It can be diagnosed with a motility test easily. Know its causes, treatment, and how to increase sperm motility.
The transmembrane migration method has permitted quantification of the effect of drugs on human sperm motility. Calcium ionophores and calcium antagonists have paradoxical effects on motility depending on the stage of sperm maturity. Drugs with membrane stabilizing properties inhibit sperm motility. Propranolol, for example, has been shown to have contraceptive activity when administered intra-vaginally. Pharmacokinetic studies have shown that the systemic availability of vaginally administered propranolol is markedly greater than after oral administration. Seminal fluid concentrations of propranolol after oral administration are similar to those in plasma, but cervicovaginal mucus concentrations are much higher, and residence times much longer. The clinical consequences of these observations await elucidation.. ...
Sperm competition occurs when the spermatozoa of one male coincide with those of another to fertilise the same eggs. In some taxa males perform multiple ejaculations, which may function in sperm competition or in maintaining a baseline density of spermatozoa in the female reproductive tract to ensure fertilisation, a process that has been termed topping up. We investigated multiple ejaculations in the European bitterling (Rhodeus amarus), a freshwater fish that oviposits in freshwater mussels. We quantified spermatozoa in the mussel mantle cavity following ejaculation, and measured sperm motility parameters of males adopting different mating tactics. Following ejaculation spermatozoa density in the mussel increased linearly, peaked after 30 s, and then declined exponentially. Spermatozoa motility parameters did not differ between male mating tactics. We parameterised a model of sperm competition for R. amarus, which accurately predicted male fertilisation probability. We discuss these results in the

We developed methods for the cryopreservation of sperm of the endangered Colorado pikeminnow Ptychocheilus lucius. Sperm were collected from a captive broodstock population of Colorado pikeminnow reared and maintained at the Dexter National Fish Hatchery and Technology Center. Our objectives were to (1) evaluate the effects on sperm motility of 24-h storage in Hanks balanced salt solution (HBSS); (2) characterize sperm motility and duration; (3) examine the relationship between sperm motility and osmotic pressure; (4) examine the effect of four cryoprotectants (dimethyl sulfoxide [DMSO], dimethyl acetamide [DMA], glycerol, and methanol [MeOH] at two concentrations [5% and 10%]) on postthaw motility; and (5) compare the effect of two cooling rates (40??C/ min and 4??C/min) on postthaw motility. The sperm samples diluted with HBSS retained higher motility (mean ??SD, 77 ?? 22%; n = 9) than did undiluted samples (12 ?? 30%; n = 9) after 24 h of storage. When exposed...
Background: Some medicinal plants with their antioxidant properties have protective effects on sperm parameters and neutralize the harmful effects of lead exposure. Objectives: The present study aimed to determine the effects of Melissa on sperm parameters and spermatogenesis quality in adult rats exposed to lead. Methods: This animal experimental study was conducted on 45 male Wistar rats weighing 180 ± 20 g, which were allocated randomly into five groups (n=9): distilled water gavages (control) (0.5 ml); intraperitoneal distilled water (i.p. control) (0.5 ml); Melissa (100 mg/kg/bw); lead acetate (10 mg/kg/bw); and lead acetate (10 mg/kg/bw) plus Melissa (100 mg/kg/bw). After a 30-day treatment, the animals were sacrificed. Sperm parameters (count, motility, morphology, and chromatins assay) and weighing of the epididymis and testis were performed. Results: The results showed that in the lead acetate plus Melissa group, epididymis weight (0.37gr vs. 0.32gr), testis weight (1.40 vs. 1.28g), ...
L-carnitine is concentrated in the epididymis, where sperm mature and acquire their motility (86). Two uncontrolled trials of L-carnitine supplementation in more than 100 men diagnosed with decreased sperm motility found that oral L-carnitine supplementation (3 grams/day) for three to four months significantly improved sperm motility (87, 88). However, no information on subsequent fertility was reported. A cross-sectional study of 101 fertile and infertile men found that L-carnitine concentrations in semen were positively correlated with the number of sperm, the percentage of motile sperm, and the percentage of normal appearing sperm in the sample (89), suggesting that L-carnitine levels in semen may be useful in evaluating male infertility. More recently, a placebo-controlled,double-blind, cross-over trial in 86 patients with male infertility found that L-carnitine (2 grams/day) supplementation for two months led to significantly improvements in sperm quality, evidenced by increases in sperm ...
Youre certainly well aware by now that being overweight or obese can put you at risk for developing many diseases including diabetes, heart problems, and cancer. But what you might not think about is how it can impact your life in other ways, from shortness of breath just trying to climb a flight of stairs to experiencing joint pain on a regular basis. And now there is research that suggests another negative outcome for heavier men, which is lower sperm quality that could affect fertility significantly.. The study, which took place at the Center for Assisted Reproduction at the Krishna IVF Clinic in Visakhapatnam, India, found that obese men are more likely to have serious sperm issues such as a lower volume of semen, lower sperm counts, and lower sperm concentration.1 These results were determined based on an evaluation of the sperm of 1,285 men in India. This was performed using computer-aided sperm analysis, which employs technology to measure a variety of sperm characteristics.. Subjects ...
Improved fertility following artificial insemination with frozen-thawed spermatozoa would offer rabbit producers faster genetic improvement. Previous work investigating cryoprotectants for rabbit spermatozoa have reported inconsistent results. Semen was collected from three rabbit bucks by artificial vagina and frozen using a standard procedure with varied cryodiluent components. Post-thaw analysis encompassed motility, sperm kinematic parameters and acrosome and membrane integrity. Spermatozoa were evaluated at 0, 2 and 4 h after thawing. Experiment 1 compared diluents with 3.5% dimethyl sulfoxide (DMSO), 1.5% acetamide, 1.75% DMSO + 0.75% acetamide or 3.5% DMSO + 1.5% acetamide. The treatment that resulted in the highest post-thaw motility (P,0.001) and acrosome integrity (P,0.001) was DMSO alone. Experiment 2 compared 3.5, 7 and 10% DMSO in the cryodiluent. The best post-thaw sperm motility (P,0.001) and linearity (P=.002) was in 3.5% DMSO, while 10% DMSO afforded higher acrosome/membrane ...
In summary, 2AG affects the in vitro functionality of human sperm by reducing motility, inhibiting capacitation and triggering the acrosome reaction.
Sperm concentration, total number and viability. The major part of the ejaculate volume is contributed by secretions from the accessory glands (seminal vesicles and prostate), so the ejaculate volume is not directly related to spermatogenesis and hence the sperm cell concentration (sperm cells/ml) varies according to the ejaculate volume. The total number of spermatozoa per ejaculate reflects the spermatogenesis and is related to the time of sexual abstinence before collection. In normal situation spermatogenesis is considered to be a constant process over time and therefore the total number of sperm per ejaculate should increase with abstinence time. The ejaculate volume is related to the secretory function of the seminal vesicles and prostate. Decreased ejaculate volume and increased sperm concentration reflects impaired accessory glands function. Vital staining of the spermatozoa allows to quantitate the fraction of living cells independently from their motility.. Spermatozoa motility. The ...
Reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2), cause oxidative cell damage and inhibit sperm function. In most oviparous fishes that spawn in seawater (SW), spermatozoa may be exposed to harmful ROS loads associated with the hyperosmotic stress of axonemal activation and ATP synthesis from mitochondrial oxidative phosphorylation. However, it is not known how marine spermatozoa can cope with the increased ROS levels to maintain flagellar motility. Here, we show that a marine teleost orthologue of human aquaporin-8, termed Aqp8b, is rapidly phosphorylated and inserted into the inner mitochondrial membrane of SW-activated spermatozoa, where it facilitates H2O2 efflux from this compartment. When Aqp8b intracellular trafficking and mitochondrial channel activity are immunologically blocked in activated spermatozoa, ROS levels accumulate in the mitochondria leading to mitochondrial membrane depolarisation, the reduction of ATP production, and the progressive arrest of sperm ...
Computer-assisted motion analyses (CASA) and flow cytometry were used to evaluate stallion spermatozoa prior to and after cryopreservation. Spermatozoa were pretreated with: (1) Hepes-buffered medium (SHB); (2) phosphatidylserine (PS) liposomes; or (3) liposomes composed of both PS and cholesterol (PSCH) prior to dilution in either SHB or skim milk-egg yolk extender (SMEY). After cooling to 5 degrees C in SHB, PS and PSCH pretreatment (23%). Spermatozoal motion parameters were higher for spermatozoa diluted in SMEY than dilution in SHB. In Experiment 2, motion parameters were compared for spermatozoa pretreated with PSCH liposomes and cryopreserved in either SMEY or a high salt-skim milk-egg yolk extender (CO). Spermatozoal motion characteristics were similar for all spermatozoal treatments after cooling at 5 degrees C. After cryopreservation, PSCH liposome-treated samples had higher percentages of motile spermatozoa than untreated samples regardless of freezing extender. Samples frozen in CO medium had
Many ejaculate traits show remarkable variation in relation to male social status. Males in disfavoured (subordinate) mating positions often invest heavily on sperm motility but may have less available resources on traits (e.g., secondary sexual ornaments) that improve the probability of gaining matings. Although higher investments in sperm motility can increase the relative fertilization success of subordinate males, it is unclear whether status-dependent differences in sperm traits could have any consequences for offspring fitness. We tested this possibility in whitefish (Coregonus lavaretus L.) by experimentally fertilizing the eggs of 24 females with the sperm of either highly-ornamented (large breeding tubercles, dominant) or less-ornamented (small tubercles, subordinate) males (split-clutch breeding design). In comparison to highly-ornamented individuals, less-ornamented males had higher sperm motility, which fertilized the eggs more efficiently, but produced embryos with impaired hatching ...
There are any number of factors that can cause a problem with male fertility. Whether it is a problem with the mans sperm count, or whether he has abnormally shaped sperm, or whether he has a problem with how the sperm are moving (also known as low sperm motility), male factor fertility problems can be very frustrating things to deal with.

Zinc is an essential microelement when it comes to male fertility and, therefore, it is a nutrient to be considered in the diagnosis, prevention, and treatment of infertility in men, according to the Journal of Reproduction and Fertility. Zinc is said to be a bodily hormone balancer that can help chemicals similar to the prostate and testosterone ...
Sperm is the key to conception from the side of the male partner. For this reason, a sperm analysis is the test required to determine the males fertility. How do you prepare for a sperm analysis and how is it done? Read the following article for more information.

Linkam Scientific has announced that a Scottish NHS laboratory has chosen the Linkam THL60-16 warm stage as a reliable solution for the assessment of sperm motility. About 25% of couples are affected by fertility problems, with around 35% of men sub-fertile and 2% infertile. One of the services provided by the NHS is fertility testing and for men that means assessment of a semen sample. The concentration, motility and the morphology of spermatozoa are all assessed to determine fertility.
Sperm racing to an egg Are you and your husband or wife attempting to Take pregnant? Think it or not a guys sperm has to be fertile and wholesome as properly. If you are not certain, have the physician verify for sperm count and motility. If an unhealthy sperm fertilizes an egg it can lead to miscarriage. If it is reduced, there are some easy issues a guy can do at house in buy to enhance the general health of his sperm and to improve sperm count.. No Medicines. Medicines and alcohol might suppress sperm manufacturing. Also sure presciption medicine might reduce sperm count this kind of as Zantac. Inform your physician if you are attempting to begin a loved ones. He or she may possibly be in a position to prescribe an option.. Reduce Out Positive Meals. Just like Medications are unhealthy for sperm, so are positive Meals. Remain absent from processed Meals and fried Meals. Consume a diet plan consisting of Meals higher in protein, green leafy veggies and reduced body fat grains. Attempt natural ...
Okay, so my boyfriend got a sperm count in October and was devastated with the news that it was only 4 million. I figured that it was because we didnt abstain long enough, but needless to say, our doctor was pushing IVF with ICSI. Anyways, after we searched long and hard online we came across this site...ordered Fertilaid For Men and took for only 1.5 weeks and went in for another sperm analysis....85 million / cc!! We still have an IUI appointment for my next cycle. This morning we woke up, were on our way to work and I started feeling nauseous, however I have severe acid reflux and just attributed it to that. Normally, acid comes up and Im good within 20 minutes and get on with my day, but this wouldnt go away. I had spinny head, and started having hot sweats, so I said we have to go home. Went home, passed out all day, and woke up feeling very hot and sweaty -- low grade fever. I woke up, ate Chinese with the family, went to the bathroom to check and see if there was any discharge and lo ...
Current artificial insemination (AI) laboratory practices assess semen quality of each boar ejaculate to decide which ones to process into AI doses. This decision is aided with two, world-wide used, motility parameters that come available through computer assisted semen analysis (CASA). This decision process, however, still results in AI doses with variable and sometimes suboptimal fertility outcomes (e.g., small litter size). The hypothesis was that the decision which ejaculates to process into AI doses can be improved by adding more data from CASA systems, and data from other sources, in combination with a data-driven model. Available data consisted of ejaculates that passed the initial decision, and thus, were processed into AI doses and used to inseminate sows. Data were divided into a training set (6793 records) and a validation set (1191 records) for model development, and an independent test set (1434 records) for performance assessment. Gradient Boosting Machine (GBM) models were ...
A study published in The Journal of Biology and Reproduction, 2011, found that DHA can improve sperm morphology. A round-headed sperm can become a healthy, cone shaped head, full of important egg-opening enzymes once again, when DHA levels are increased. DHA also plays a role in sperm motility. An increase in DHA levels was shown to play a role in the fluidity for sperm tail bending and flexing required for forward movement of sperm. Another study showed that men who consumed 3 or more cups of coffee per day had reduced sperm concentration and total sperm count, as well as lower sperm quality. Vitamin C has been shown to improve sperm quality and protect sperm from DNA damage; helping to reduce the chance of miscarriage and chromosomal problems. Vitamin C also appears to keep sperm from clumping together, making them more motile. Another study, published by Fertility and Sterility, 11/10/2011, showed that men who ate more whole grain cereals (wheat, barley, oats) had high sperm concentration and ...
The Cantabrian brown bear survives as a small remnant population in northern Spain and semen cryopreservation for future artificial insemination is one of the measures being implemented for conservation of this species. As part of this program we investigated the value of adding heat shock protein A8 (HSPA8) to media (N-[Tris(hydroxymethyl)methyl]-2-aminoethanesulfonic acid-TRIS-fructose with 20% egg yolk) used for chilling and cryopreserving the spermatozoa. Semen samples from eight brown bears were obtained by electroejaculation during the breeding season. In experiment 1, we tested three concentrations of HSPA8 (0.5, 1, and 5 μg/mL) to determine whether sperm motility (computer assisted sperm analysis system) and sperm survival could be improved during refrigeration (5 °C) up to 48 hours. Results showed that sperm viability (test with propidium iodide) was improved by the addition of 0.5 and 5 μg/mL HSPA8. In experiment 2, HSPA8 was added to the cryopreservation media (6% final glycerol ...
Male Infertility. Concentrations of L-carnitine can be found in the epididymis and sperm cells of the male reproductive system. Scientists have found that L-carnitine plays a key role in sperm motility and respiration, making adequate carnitine levels essential for male fertility. Clinical research demonstrates that L-carnitine supplementation can benefit men with fertility problems. In a study published in 2005, researchers gave 30 participants with male infertility two grams of L-carnitine per day for three months. Sperm health was measured at baseline and after carnitine treatment. Results showed that participants who received L-carnitine and had normal mitochondrial function showed a significant increase in sperm motility above baseline levels.. In another study, researchers wanted to know if carnitine supplementation would reduce infertility among 60 men with low sperm counts, atypical sperm or reduced sperm motility. Participants were given two grams of L-carnitine and one gram of ...
In mammals, after coitus a small number of spermatozoa enter the uterine tube and following attachment to uterine tube epithelium are arrested in a non-capacitated state until peri-ovulatory signalling induces their detachment. Whilst awaiting release low numbers of spermatozoa continually detach from the epithelium and the uterine tube reservoir risks depletion. There is evidence of attachment of spermatozoa to uterine epithelium in several species which might form a potential pre-uterine tube reservoir. In this study we demonstrate that: (1) dog spermatozoa attach to uterine epithelium and maintain flagellar activity, (2) in non-capacitating conditions spermatozoa progressively detach with a variety of motility characteristics, (3) attachment is not influenced by epithelial changes occurring around ovulation, (4) attachment to uterine epithelium slows capacitation, (5) capacitated spermatozoa have reduced ability to attach to uterine epithelium, (6) under capacitating conditions increased ...

It is evident that genetic variation plays a substantial role in the etiology of male infertility. Studies of children fathered through intracytoplasmic sperm injection or ICSI have revealed mutations on the AZF region of the Y chromosome linked to male infertility. Mutations of other genes may also be involved. Candidates would include genes for the androgen receptor, follicle-stimulating hormone, and luteinizing hormone, and genes involved in the regulation of spermatogenesis and sperm motility. Mutations in mitochondrial DNA have been linked to poor sperm motility and raise the possibility that some types of male subfertility may be inherited only through the female line.. We propose to assess the role of folate/homocysteine status and MTHFR and CBS gene variants in infertile men in Sweden with no known cause for their infertility and whose wives/partners appear to be fertile. We propose to perform the study in Sweden since Sweden, unlike the U.S., at present does not mandate the enrichment ...
L-carnitine is concentrated in the epididymis, where sperm mature and acquire their motility (86). Two uncontrolled trials of L-carnitine supplementation in more than 100 men diagnosed with decreased sperm motility found that oral L-carnitine supplementation (3 grams/day) for three to four months significantly improved sperm motility (87, 88). However, no information on subsequent fertility was reported. A cross-sectional study of 101 fertile and infertile men found that L-carnitine concentrations in semen were positively correlated with the number of sperm, the percentage of motile sperm, and the percentage of normal appearing sperm in the sample (89), suggesting that L-carnitine levels in semen may be useful in evaluating male infertility. More recently, a placebo-controlled,double-blind, cross-over trial in 86 patients with male infertility found that L-carnitine (2 grams/day) supplementation for two months led to significantly improvements in sperm quality, evidenced by increases in sperm ...
Sperm quality can be affected by many factors such as foods, physical activity, and smoking. Recently, researchers found that ozone exposure may adversely affects sperm quality.
To mount an immune response, T lymphocytes must successfully search for foreign material bound to the surface of antigen-presenting cells. How T cells optimize their chances of encountering and responding to these antigens is unknown. T cell motility in tissues resembles a random or Levy walk and is regulated in part by external factors including chemokines and lymph-node topology, but motility parameters such as speed and propensity to turn may also be cell intrinsic. Here we found that the unconventional myosin 1g (Myo1g) motor generates membrane tension, enforces cell-intrinsic meandering search, and enhances T-DC interactions during lymph-node surveillance. Increased turning and meandering motility, as opposed to ballistic motility, is enhanced by Myo1g. Myo1g acts as a turning motor and generates a form of cellular flânerie. Modeling and antigen challenges show that these intrinsically programmed elements of motility search are critical for the detection of rare cognate antigen-presenting
I found that helped as well and then once you get the upward lift of your arms then the next one is to, to virtually bounce the arm so it is pushing down to get the straightness which I used a, a tin of baked beans in my hand because it was a weight on it, to, to stretch the tendons because obviously being fixed in a position for a long time your tendons also shrink so, its quite a lot of work but it is well worth every minute of it. You know you do appreciate it in the end and you find that doing your normal everyday things which you start to do, I started to do a bit quick, but you do them, youre exercising anyway because your using weight and lifting and your moving the arm. I dont think I ever did any twisting movements on the arms, it was always just sort of virtually up and down and then you get your straightness and your, your bend from that. ...
Our clinical catamnestic studies on cases of sterility with a proven sensitization against spermatozoa revealed a statistically significant decrease of pregnancies only in patients with positive spermantibody tests over a period longer than 3 years. A direct spermimunological etiology of sterility can not yet be derived. In the investigated 759 cases a sensitization against spermatozoa was detected in 93 cases. In 11 patients the spermantibodies proved to be positive longer than 3 years. Washed spermatozoa were used as antigen in the applied test methods. It may very well be possible, that the results point in a different direction once we are applying a particular fertility diminishing spermatozoa antigen.

The study of dynamic cellular processes in living cells is central to biology and is particularly powerful when the motility characteristics of individual objects within cells can be determined and analysed statistically. However, commercial programs only offer a limited range of inflexible analysis modules and there are currently no open source programs for extensive analysis of particle motility. Here, we describe ParticleStats (http://www.ParticleStats.com), a web server and open source programs, which input the X,Y coordinate positions of objects in time, and output novel analyses, graphical plots and statistics for motile objects. ParticleStats comprises three separate analysis programs. First, ParticleStats:Directionality for the global analysis of polarity, for example microtubule plus end growth in Drosophila oocytes. Second, ParticleStats:Compare for the analysis of saltatory movement in terms of runs and pauses. This can be applied to chromosome segregation and molecular motor-based movements.

What is ICSI?. In most cases of couples finding it difficult to conceive, it has been found that men suffer from infertility conditions more often. There are tests that can be easily conducted in order to find the underlying causes of infertility in men. Many clinics have an IVF success rate in Singapore that is dependent on successful treatment of infertility causes in men. One of the successful ways infertility is treated in men is by ICSI or intra cytoplasmic sperm injection. The benefits of this treatment method are several of which in most cases where the sperm count is low in a man or sperm mobility is a concern, this kind of treatment is resorted to.. How it works?. ICSI or intra cytoplasmic sperm injection is usually a well proven technique that can help counter low sperm count or sperm mobility issues in men. Such causes are common in men, which leads to failure in conception for many couples. Whereas such conditions would have led to couples having to resort to donor sperms for ...

In 1876, Robert Koch (1843-1910) established that microorganisms can cause disease. He found that the blood of cattle that were infected with anthrax always had large numbers of Bacillus anthracis. Koch found that he could transmit anthrax from one animal to another by taking a small sample of blood from the infected animal and injecting it into a healthy one, and this caused the healthy animal to become sick. He also found that he could grow the bacteria in a nutrient broth, then inject it into a healthy animal, and cause illness. Based on these experiments, he devised criteria for establishing a causal link between a microorganism and a disease and these are now known as Koch's postulates.[18] Although these postulates cannot be applied in all cases, they do retain historical importance to the development of scientific thought and are still being used today.[19] The discovery of microorganisms such as Euglena that did not fit into either the animal or plant kingdoms, since they were ...
