Glutathione-independent prostaglandin D2 synthase in ram and stallion epididymal fluids: origin and regulation. (1/2200)

Microsequencing after two-dimensional electrophoresis revealed a major protein, glutathione-independent prostaglandin D2 synthase (PGDS) in the anterior epididymal region fluid of the ram and stallion. In this epididymal region, PGDS was a polymorphic compound with a molecular mass around 30 kDa and a range of pI from 4 to 7. PGDS represented 15% and 8% of the total luminal proteins present in this region in the ram and stallion, respectively. The secretion of the protein as judged by in vitro biosynthesis, and the presence of its mRNA as studied by Northern blot analysis, were limited to the proximal caput epididymidis. Using a specific polyclonal antibody raised against a synthetic peptide, PGDS was found throughout the epididymis, decreasing in concentration toward the cauda region. PGDS was also detected in the testicular fluid and seminal plasma by Western blotting. Castration and efferent duct ligation in the ram led to a decrease in PGDS mRNA and secretion. PGDS mRNA was not detected in the stallion 1 mo after castration, and it was restored by testosterone supplementation. This study showed that PGDS is present in the environment of spermatozoa throughout the male genital tract. Its function in the maturation and/or protection of spermatozoa is unknown.  (+info)

Characterisation of the conformational and quaternary structure-dependent heparin-binding region of bovine seminal plasma protein PDC-109. (2/2200)

PDC-109, the major heparin-binding protein of bull seminal plasma, binds to sperm choline lipids at ejaculation and modulates capacitation mediated by heparin. Affinity chromatography on heparin-Sepharose showed that polydisperse, but not monomeric, PDC-109 displayed heparin-binding capability. We sought to characterise the surface topology of the quaternary structure-dependent heparin-binding region of PDC-109 by comparing the arginine- and lysine-selective chemical modification patterns of the free and the heparin-bound protein. A combination of reversed-phase peptide mapping of endoproteinase Lys-C-digested PDC-109 derivatives and mass spectrometry was employed to identify modified and heparin-protected residues. PDC-109 contains two tandemly arranged fibronectin type II domains (a, Cys24-Cys61; b, Cys69-Cys109). The results show that six basic residues (Lys34, Arg57, Lys59, Arg64, Lys68, and Arg104) were shielded from reaction with acetic anhydride and 1,2-cyclohexanedione in heparin-bound PDC-109 oligomers. In the 1H-NMR solution structures of single fibronectin type II domains, residues topologically equivalent to PDC-109 Arg57 (Arg104) and Lys59 lay around beta-strand D on the same face of the domain. In full-length PDC-109, Arg64 and Lys68 are both located in the intervening polypeptide between domains a and b. Our data suggest possible quaternary structure arrangements of PDC-109 molecules to form a heparin-binding oligomer.  (+info)

Occurrence of prostasome-like membrane vesicles in equine seminal plasma. (3/2200)

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)

Semen quality and reproductive hormones before orchiectomy in men with testicular cancer. (4/2200)

PURPOSE: To obtain information about preorchiectomy gonadal function in patients with testicular germ cell cancer to improve the clinical management of fertility and other andrologic aspects in these men. PATIENTS AND METHODS: In group 1, a group of 83 consecutive patients with testicular germ cell cancer (TGCC) investigated before orchiectomy, semen analysis was carried out in 63 patients and hormonal investigations, including measurement of follicle-stimulating hormone, luteinizing hormone (LH), testosterone, estradiol, sex hormone-binding globulin (SHBG), inhibin B, and human chorionic gonadotropin (hCG), in 71 patients. Hormone levels in patients with elevated hCG (n = 41) were analyzed separately. To discriminate between general cancer effects and specific effects associated with TGCC, the same analyses were carried out in a group of 45 consecutive male patients with malignant lymphoma (group 2). Group 3 comprised 141 men employed in a Danish company who served as controls in the comparison of semen parameters. As a control group in hormone investigations, 193 men were selected randomly from the Danish National Personal Register to make up group 4. RESULTS: We found significantly lower sperm concentration (median, 15 x 10(6)/mL; range, 0 to 128 x 10(6)/mL) and total sperm count (median, 29 x 10(6)/mL; range, 0 to 589 x 10(6)) in patients with testicular cancer than in patients with malignant lymphomas (sperm concentration: median, 48 x 10(6)/mL; range, 0.04 to 250 x 10(6)/mL; sperm count: median, 146 x 10(6); range, 0.05 to 418 x 10(6)) (P < .001 and P < .001) and healthy men (sperm concentration: median, 48 x 10(6)/mL; range, 0 to 402 x 10(6)/mL; sperm count: median, 162 x 10(6); range, 0 to 1253 x 10(6)) (P < .001 and P < .001). FSH levels were increased in men with testicular cancer (median, 5.7 IU/L; range, 2.0 to 27 IU/L) compared with both men with malignant lymphomas (median, 3.3 IU/L; range, 1.01 to 12.0 IU/L) and healthy controls (median, 4.1 IU/L; range, 1.04 to 21 IU/L)(P = .001 and P = .007, respectively). Surprisingly, we found significantly lower LH in the group of men with TGCC (median, 3.6 IU/L; range, 1.12 to 11.9 IU/L) than in healthy men (median, 4.7 IU/L; range, 1.3 to 11.9 IU/L) (P = .01). We could not detect any differences between men with testicular cancer and men with malignant lymphomas and healthy men with regard to serum levels of testosterone, SHBG, and estradiol. Men with testicular cancer who had increased hCG levels had significantly lower LH and significantly higher testosterone and estradiol than those without detectable hCG levels. CONCLUSION: Spermatogenesis is already impaired in men with testicular cancer before orchiectomy. Neither local suppression of spermatogenesis by tumor pressure nor a general cancer effect seems to fully explain this impairment. The most likely explanation is preexisting impairment of spermatogenesis in the contralateral testis in men with testicular cancer. The question of whether also a pre-existing Leydig cell dysfunction is present in men with testicular cancer could not be answered in this study because the tumor seems to have a direct effect on the Leydig cells. Men with testicular cancer had low LH values as compared with controls. We speculate that increased intratesticular level of hCG also in men without measurable serum hCG may play a role by exerting LH-like effects on the Leydig cells, causing increased testosterone and estrogen levels and low LH values in the blood.  (+info)

Is intracytoplasmic sperm injection necessary for couples undergoing in vitro fertilization-embryo transfer with normal semen analyses but failing hamster egg penetration assays? (5/2200)

PURPOSE: Our purpose was to assess whether in vitro fertilization (IVF)-embryo transfer (ET) candidate couples with basically normal semen analyses but failing zona-free hamster egg penetration assay (HEPA) scores benefit from intracytoplasmic sperm injection (ICSI). METHODS: Twenty consecutive IVF candidate couples with normal-borderline semen analyses and failing HEPA scores were recruited. Mature oocytes obtained from each woman were randomly divided between ICSI (group I; n = 126 oocytes) and standard insemination techniques (group II; 138 oocytes). Fertilization (two pronuclei) and cleavage (2-4 cells) rates were assessed for both groups. RESULTS: There were no statistically significant differences between the two groups with respect to (mean +/- standard error of the mean) fertilization (group I, 63.1 +/- 7.75; group II, 77.8 +/- 4.7%) or cleavage (group I, 87.3 +/- 2.4%; group II, 91.2 +/- 3.5%) rates. CONCLUSIONS: ICSI is not beneficial for IVF-ET when sperm samples demonstrate a failing HEPA score but have normal or minimally compromised semen analysis parameters.  (+info)

Purification of a 76-kDa iron-binding protein from human seminal plasma by affinity chromatography specific for ribonuclease: structural and functional identity with milk lactoferrin. (6/2200)

A pink-colored iron-binding protein has been found in large amount in human seminal plasma and identified as a lactoferrin isoform. Its purification, by a modification of a three-step chromatography procedure developed in an attempt to purify a ribonuclease from the same fluid, provided about 15-18 mg of pure protein from 100 ml of seminal plasma. Despite its ability to bind a ribonuclease ligand during the affinity step, the iron-binding protein did not display any detectable RNase activity in a standard assay with yeast RNA as substrate. It showed an apparent molecular weight of 76 kDa and resulted to be quite similar, if not identical, to human milk lactoferrin in many respects. Its N-terminal sequence (31 amino acid residues) starting with Arg-3 was identical to that of one of the N-terminally truncated lactoferrin variants isolated from human milk. Moreover, the amino acid sequence of a number of peptides, which represented about 23% of the entire sequence, has been also shown to be identical to that of the corresponding peptides of human milk lactoferrin. Double diffusion analysis revealed full recognition by antibodies anti-human milk lactoferrin of the human seminal plasma protein. Using immunoblotting analysis, both human milk lactoferrin and human seminal protein were recognized by antibodies anti-milk lactoferrin. When tested for its iron binding capacity, with Fe-NTA as iron donor, the protein purified was able to bind iron up to 100% saturation, as judged by absorbance at 465 nm.  (+info)

A 105- to 94-kilodalton protein in the epididymal fluids of domestic mammals is angiotensin I-converting enzyme (ACE); evidence that sperm are the source of this ACE. (7/2200)

SDS-PAGE analysis of luminal fluid from the ram testis and epididymis revealed a protein of about 105 kDa in the fluid in the caput epididymal region. The molecular mass of this fluid protein shifted from 105 kDa to 94 kDa in the distal caput epididymidis and remained at 94 kDa in the lower regions of the epididymis. The possible sperm origin of this protein was suggested by the decrease in intensity of a 105-kDa compound on the sperm plasma membrane extract and by its total disappearance from the fluid of animals with impaired sperm production caused by scrotal heating. The 94-kDa protein was purified from ram cauda epididymal fluid, and a rabbit polyclonal antiserum was obtained. This antiserum showed that membranes of testicular sperm and sperm from the initial caput were positive for the presence of an immunologically related antigen. The protein was immunolocalized mainly on the flagellar intermediate piece, whereas in some corpus and caudal sperm, only the apical ridge of the acrosomal vesicle was labeled. The purified protein was microsequenced: its N-terminal was not found in the sequence database, but its tryptic fragments matched the sequence of the angiotensin I-converting enzyme (ACE). Indeed, the purified 94-kDa protein exhibited a carboxypeptidase activity inhibited by specific blockers of ACE. All the soluble seminal plasma ACE activity in the ram was attributable to the 94-kDa epididymal fluid ACE. The polyclonal antiserum also showed that a soluble form of ACE appeared specifically in the caput epididymal fluid of the boar, stallion, and bull. This soluble form was responsible for all the ACE activity observed in the fluid from the distal caput to the cauda epididymidis in these species. Our results strongly suggest that the epididymal fluid ACE derives from the germinal form of ACE that is liberated from the testicular sperm in a specific epididymal area.  (+info)

Seminal tract infections: impact on male fertility and treatment options. (8/2200)

Bacterial and viral infections of the genital tract may be important aetiological factors for male infertility. Infectious processes may lead to deterioration of spermatogenesis, impairment of sperm function and/or obstruction of the seminal tract. Detection of bacteria in semen does not necessarily signify infection since bacteriospermia may represent contamination, colonization or infection. Reported prevalence of Ureaplasma urealyticum in human semen varies from 10 to 40%. Enterobacteria can even be found in up to 90% of semen samples depending on the sensitivity of detection methods used. Chlamydia trachomatis is the most frequent sexually transmitted bacterial organism in industrialized countries. It is suggested that its main influence is due to sexual transmission resulting in tubal disease and subsequent infertility in the female partner rather than a direct influence on male reproductive functions. The effect of leukocytospermia on male fertility is controversial. This is probably due to different detection methods, different populations studied and to the fact that leukocyte subtypes in semen may have different functions. In addition to potentially negative effects, leukocytes may even have protective effects on spermatozoa. Only recently have amplification methods been established to detect viruses in semen with high sensitivity and specificity. It is unclear if these infections significantly contribute to male infertility.  (+info)

In this large, prospective and well-controlled study of semen quality of annual cohorts of young men from the general population, statistically significant increases in sperm concentration and total sperm counts over the past 15 years were detected. However, it is of concern that these men from the general population in the new millennium had significantly lower sperm concentrations and total sperm counts than recently examined fertile men and men of a historical cohort of male partners of infertile couples. Both sperm concentration and sperm morphology measures according to strict criteria are known to be informative semen measurements for discriminating between fertile and infertile men.41 Therefore, there is reason to be concerned about future fertility of young Danish men. Smaller cross-sectional studies of men from the general populations in other European countries have shown similar high frequencies of men with poor semen quality.38-40 ,42 ,43 Thus, poor semen quality seems to be a ...

We linked information on all men in couples with fertility problems who had a semen analysis done at the Sperm Analysis Laboratory in Copenhagen during 1963-95 (n=32 442) with data in the Danish Cancer Registry, which holds information on all cases of cancer in the Danish population from 1943 to 1995.15 Men who visited the laboratory for other reasons (such as semen analysis after vasectomy) were excluded from the analysis. The Copenhagen laboratory is one of several public semen analysis laboratories in Denmark and examines semen samples mostly from men in the area of Copenhagen. Men are referred to the clinic by general practitioners and urologists, and the investigations are paid for through the public health system. Men with cancer before the date of semen analysis were excluded. For men who had multiple semen tests only their first test was used in the analysis. Similarly, only the first cancer diagnosis in a given man was included in the analysis. The methods used for analysis of semen ...
Specimen collection. Forty-one bovine semen samples were collected from healthy bulls of different breeds using an artificial vagina. The samples were obtained from a company specializing in reproduction programs and artificial insemination, packed in metal-free conical tubes (15 mL), and kept in liquid nitrogen from the time of collection until delivery of the samples, after which the samples were kept in a freezer (-80 °C) until analyses. These whole samples were used to estimate background levels for essential metals in bovine semen.. For the development of analytical methodology, four different bovine semen pools were prepared using sperms that were collected from six ordinary animals.. Preparation of bovine semen samples for direct introduction To evaluate the calibration method in aqueous medium and by matrix-matching, the samples (200 µL) were diluted 1:50 in a solution containing 0.01% v/v Triton® X-100 and 0.5% v/v HNO3. Ir, Rh and Y were added as internal standards to all samples to ...
Three experiments were done at the University of Free State in Bloemfontain in 2014 and in 2015. Experiment 1 was carried to evaluate the effect of breed (Dorper and SAMM) on fresh ram semen parameters before cryopreservation. Experiment 2 was carried to evaluate the effects of breed difference, different extenders and different freezing protocols on the viability of frozen ram semen during different incubation periods after thawing. Experiment 3 was carried to evaluate effects of breed, extender and freezing protocol on in vitro fertilizing capacity of frozen-thawed ram semen. Experiments 1 and 2 were done in 2014 during the breeding season while experiment 2 was done in 2015 from mid of January until the end of April. For the first trial, the semen was collected with the aid of artificial vagina from two breeds of rams. The ejaculates were evaluated for the following parameters: semen volume, semen colour, sperm motility, sperm concentration, percentage live/dead sperm and sperm morphology. ...
This is a very large retrospective review from a single andrology lab studying the impact of BMI on semen parameters with ,10,000 infertile subjects - one of the largest studies to date. The findings demonstrate the impact of obesity on semen analysis and subsequently fertility status. As BMI increased, there was a statistically significant decline in volume, concentration, count, viability, and progressive motility. Interestingly, morphology was not different. There were no comments on medical conditions of the subjects (ie hypogonadism, varicocele, diabetes, hypothyroid/hyperthyroid, medications taken, etc.) It would be interesting to see if the BMI effects on semen analysis would be the same for fertile men divided into respective BMI categories in this study.. ...
Bull semen sounds like a bizarre investment, but it is an extremely valuable commodity in the dairy and cattle farming world. To be precise, the way most people would invest in bull semen would be buying a bull that produces a lot of it. So who the heck is buying the bull semen you are going to be selling? Dairy farmers need their cattle to become pregnant at least once a year in order to continue to produce milk; they also want those calves to be genetically predisposed to be produce a large quantity of milk. Cattle farmers likewise want their female cows to produce calves that produce a large amount of good lean meat. They buy straws of semen (almost like test tubes of semen with egg whites mixed in) from top-rated bulls many times a year (100s or 1000s of straws depending on the size of their operation). ...
While it is well known that testes may be a reservoir for long term persistence of Ebola virus (EBOV), the dynamics of the persistence of EBOV in semen remained unexplored. We aimed to estimate the probability of EBOV RNA clearance in semen over time.. We enrolled a cohort of 25 men discharged from three Ebola Treatment Units (ETU) in Coastal region of Guinea between February 6, 2015 and July 6, 2015. Semen specimens were obtained every 3-6 weeks until reaching non-detectable levels of EBOV RNA (eg, CT values ≥ 45) on two consecutive samples. Specimens were tested on-site using Altona RT-PCR. Furthermore, a nonlinear mixed effect model was used to estimate the slope of evolution of Ct values over time. A total of 116 semen samples were collected. The median time between EVD onset and first semen collection was 49 days (IQR: 40-85). The median time between first and last semen collection was 193 days (IQR: 150-204). Of the 25 participants, 18 (72%) had a positive EBOV RT-PCR in the first semen ...
The objective of this study was to determine rabbit seminal plasma enzyme activity. Furthermore, correlations between semen parameters and enzyme activity and male age were examined. The study was performed using 17 New Zealand White males from 5 to 9 mo old. Overall, 252 semen samples were collected from bucks from May to September. Semen characteristics were analysed and the seminal plasma was obtained by centrifugation. The activities of alanyl aminopeptidase (APN), aspartate transaminase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GOT), lactate dehydrogenase (LDH) and alkaline phosphatase (ALKP) in the seminal plasma fluid were measured. Significant differences between males were found in APN, GGT, LDH, ALKP and ALT activities (P<0.05). No significant differences between enzyme activity and male age were found. We also observed significant positive correlations between male age and sperm concentration (r=0.26), progressive motility (r=0.17) and amplitude of ...

HealthDay Reporter. (HealthDay News) -- Zika virus might not remain in the semen of some infected men as long as previously thought, a small study suggests.. The researchers said Zika may only be present in semen for about a month. Previous research had suggested that Zika virus can be found in semen for as long as 188 days after the onset of symptoms.. The new study included 12 men in French Guiana who had Zika virus. Four of the men never had any detectable Zika in their semen. One excreted Zika virus in his semen for at least three days. And seven had Zika-laced semen for at least a month, the researchers reported. The maximum duration of detectable Zika in semen in the study was 45 days.. These data suggest that not all men who are symptomatically infected with Zika virus will have Zika virus RNA detectable in semen, Dr. Franck de Laval, of the Military Center for Epidemiology and Public Health in Marseille, France, and colleagues wrote.. The results also showed that Zika does replicate in ...

The concept that an elevation of testicular temperature results in impairment of spermatogenesis is widely accepted. Here, current knowledge concerning genital heat stress and its consequences in men is reviewed. Duration of sitting during work positively correlates with daytime scrotal temperatures and daytime scrotal temperature negatively correlates with semen quality. However, the assumed negative correlation between duration of sitting and semen quality could not be shown in the available studies. Fertility parameters of professional drivers with long periods of sitting in vehicles were impaired; however, for predominantly affected drivers of vans, trucks or industrial heavy machinery potential confounders have to be considered. Wearing tight fitting compared with loose-fitting underwear is associated with significantly higher scrotal temperatures. However, available observations suggesting a link between tight-fitting underwear or trousers and impaired semen quality are not convincing. ...

At least two mature oocytes were recovered in each cycle. The correlation between the percentages of normal forms and fertilization rates of mature oocytes was analyzed. The results demonstrate that the percentage of normal forms in both the raw semen and swim-up sample of patients with poor fertilization was significantly lower than in those with acceptable fertilization. The percentages of normal forms both in raw semen and in swim-up sample were significantly ...
The study, published Thursday, Feb. 6, in the journal Human Reproduction, suggests that even healthy men may become progressively less fertile as time goes by. Prior studies on semen quality typically included men who came to fertility clinics, said Brenda Eskenazi, professor of epidemiology and maternal and child health at UC Berkeleys School of Public Health, and co-author of the study. This is one of the first studies to focus on men with no known fertility concerns, giving us a better sense of whether age affects semen quality in a healthy population. The researchers recruited 97 men between the ages of 22 and 80 who were employed or retired from Lawrence Livermore National Laboratory. Samples were brought to the onsite research laboratory within two hours after collection to accurately measure sperm motility - its liveliness and direction of movement - and other indicators of semen quality. The researchers gathered extensive medical, lifestyle and occupational exposure history from the ...

The aim of this study was to examine the effects of extenders on the quality and fertility of cooled Formosan sambar stag semen after artificial insemination. Result showed that the sperm motility score (SMS), sperm concentration, and sperm viability (VIAB) of Formosan sambar stag semen collected by electro-ejaculation were 4.7, 8.9×108 sperms/mL and 87.0%, respectively. The SMS of semen diluted with TCY or TY extenders were not decreased by cooling at 4℃ for 12 h (5.0 and 5.0), but those of semen diluted with CY extender were decreased from 5.0 to 4.0.

Semen analysis. This is a very important test for the male partner. Your doctor may ask for one or more semen specimens. Semen is generally obtained by masturbating or by interrupting intercourse and ejaculating your semen into a clean container. A laboratory analyzes your semen specimen for quantity, colour and presence of infections or blood ...
The objective of this study was to evaluate the effects of selection for increased size of testes on semen and testis characteristics. Boars from a line selected for increased size of testes at 150 d of age (TS, n = 25) and a randomly selected control line (C, n = 18) were used. Semen was collected three times per week for 3 wk (TRT1) then daily for 3 wk (TRT2) beginning when boar age averaged 276 d. It was followed by a 4-wk period of one collection per week and then the TRT1-TRT2 sequence was repeated. After 64 collections, boars were castrated and testes were evaluated for sperm numbers. Volume of semen, percentage of motile sperm cells, and percentage of abnormal cells in the semen did not differ (P | .05) between lines. Concentration of sperm cells in the semen was greater for TS boars at TRT 1 (35.0 million cells/mL, P | .10) and TRT 2 (29.5 million cells/mL, P | .01). Number of sperm cells per ejaculate was greater for TS boars (6.1 and 4.3 billion cells for TRT 1 and TRT 2, respectively; P | .05
Biomarkers of vaginal exposure to semen, long used in forensic medicine, are now becoming important in the development of vaginal microbicides to prevent HIV/STIs and the development of contraceptives. Semen biomarkers could help evaluate the safety of a new physical or chemical barrier, give preliminary indication of the effectiveness of physical barriers such as diaphragms or condoms, and provide information on unprotected intercourse among participants in a clinical trial who have been advised to use condoms. Candidate biomarkers of semen exposure fall into two broad categories: (1) biomarkers of seminal plasma, among which prostate-specific antigen (PSA) is the best characterized; and (2) biomarkers of spermatozoa and other cells present in semen. This paper, authored by a working group of investigators performing research in the field of semen biomarkers, summarizes the characteristics of an ideal semen biomarker, reviews preclinical and clinical data on existing and potential biomarkers, and

I am writing this letter to recommend the QwikCheck™ GOLD EQUINE semen analyzer produced by A-TECH (the veterinary division of Medical Electronic Systems). Ariella Arabians and A-Tech worked in partnership to develop the QwikCheck™ GOLD analyzer in 2012. We ran the alpha site testing right before the 2013 season and assisted in providing semen samples for the development of the algorithm. Based on the successful product development, the analyzer was used to test and provide cooled semen doses to our customers in the 2013 season.. I personally use the analyzer and find that it provides accurate and precise results. It reports sperm concentration, % motility, % progressive motility, % normal morphology, velocity and the number of sperm, progressive sperm and motile sperm per sample volume. We have used it extensively for setting up doses and found that, through the use of the system, we have been more efficient in the distribution and QC of cooled semen shipments. In addition, the label with ...

Researchers in Germany have discovered that a protein found in semen makes HIV 100,000 times more virulent than it is alone - thus helping to explain why more than 80 percent of human-immunodeficiency-virus (HIV) infections are transmitted via sexual intercourse.. The team of German scientists had initially set out to determine whether semen contained factors that inhibit the HIV infection, according to the report published in the journal Cell.. But surprisingly, the HIV/AIDS researchers in Hanover and Ulm, Germany, found that fragments of prostatic acidic phosphates isolated from human semen form tiny fibers known as amyloid fibrils, which they call Semen-derived Enhancer of Virus Infection or SEVI. Those fibrils capture HIV particles and help them to penetrate target cells, thereby increasing the infection rate by up to several orders of magnitude.. We were not expecting to find an enhancer, and we were even more surprised about the strength, says report co-author Frank Kirchhoff, a ...
On March 12, 2017 by abah guru. Can women become addicted to semen, as if it were some form of drug? Surprisingly, scientific studies say, yes.. This might raise some eyebrows among feminists, but scientific results do show this to be the case. They are not sure exactly why (chemically), but women can become reliant on a mans semen.. The semen must be introduced vaginally and not orally. Orally it doesnt seem to have any affect, probably because the contents of the semen get broken down and denatured from the stomach acids. The affective-chemical component is rendered useless during this method of application.. What scientists have found, is that when a woman has vaginal sex with a man; and the man ejaculates inside of her, that the semen, if it is not washed out immediately, gets absorbed by the lining of the vagina and makes its way into the bloodstream. Once the semen has been absorbed, it has been found that it not only aids in relieving anxiety and depression in women, but also cuts ...
In this study, the semen analysis results of a fertile population were compared with those from a subfertile population, in order to establish normal cut-off values for the standard semen parameters with the aid of receiver operating characteristic (ROC) curve analysis. The fertile group comprised healthy males (n = 107) without any history of fertility problems, the partners of whom had had a spontaneous pregnancy within one year of unprotected intercourse and were pregnant at the time of the males inclusion into the study. A total of 103 males from couples attending the infertility clinic, and with an initial sperm count of <20 × 106/ml were recruited to form the subfertile population. The best discriminating parameter between the two populations was sperm morphology evaluated according to WHO criteria at a cut-off point of 31% normal spermatozoa. The other cut-off values were at 8% for the acrosome index, 45% for motility, and 4% normal spermatozoa for strict criteria. Recalculating the ...
Third-party testing is done routinely to monitor product quality. Water samples, extender and semen doses are tested every month for bacteria. Random semen doses are also sent in for third-party evaluation every month to be assessed for multiple semen characteristics.. Birchwood utilizes Sperm Vision®, a computer-assisted semen-analysis (CASA) technology, to standardize the evaluation and processing of all semen doses. Additionally, Birchwood conducts in-house testing for dose concentrations by randomly checking doses from each production facility every week. NucleoCounter® technology is used to benchmark and correlate results for process-control.. Samples are kept from every batch of semen that is processed. These samples are evaluated for motility multiple times through day seven. Customers are notified if the product falls out of acceptable range for minimum standards for motility between delivery and day seven.. ...

Ia menjelaskan, kenaikan harga semen selalu menjadi ritual akhir tahun yang terjadi di Kota Balikpapan. Pada tahun 2008, harga semen melonjak karena adanya PON XVII di Kaltim tetapi stoknya masih tersedia bebas di pasaran.. Pada 2010 pun semen juga mengalami kenaikan harga tetapi masih dalam tahap wajar. Kenaikan tahun ini yang menjadi preseden buruk karena semen juga langka di pasaran, terangnya.. Namun kata Tantin, perlu dilakukan investigasi mendalam agar kenaikan semen ini tidak terus berlanjut. Dia menyetujui usul untuk dilakukan penyelidikan bersama oleh aparat kepolisian. Kita akan coba libatkan kepolisian. Kita ada data-datanya soal pasokan semen dari produsen katanya sudah sesuai kuato, katanya. ...

In seasonal production systems, demand for semen from young genetically elite bulls often exceeds supply. However, compared with their mature contemporaries, both the quantity and quality of semen from young bulls is relatively poor, gradually improving in the months following onset of puberty. Thus, there is a requirement to expedite the onset of sexual maturation in young bulls in order to ensure the timely availability of consistently high quality semen. Sexual development in the bull is regulated by both genetics and nutritional status, particularly during early life.. As part of a large Science Foundation Ireland funded project we are examining the role of both early life nutrition and genetics in regulating sexual development and subsequent semen quality and fertility in young bulls. Key fertility traits including those related to sperm production capacity and quality are known to be heritable and thus hold potential for genetic selection. ...
Prior to producing the semen sample, the semen collection container is subjected to visual inspection for signs of damage, such as, for instance, cracks. Then the entire labeling of the semen collection container is checked against a label that bears the identification code as well as the names and dates of birth of both the woman and the man. This ensures the correct assignment of the semen sample. Before being asked to produce a semen specimen, a laboratory questionnaire is handed out to the male patient. The questionnaire has to be completed and signed by the male patient. It remains with the patient during semen collection. The questionnaire containing additional information on the male patient must be handed in directly to the laboratory together with the sample container as soon as the semen specimen has been produced. In the laboratory, everything is checked once again. In the case of incomplete labeling of the semen sample container or if the questionnaire is not filled in completely, ...
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 ...

Too often the informed decision to use sexed semen is counterproductive because of less than careful herd management and inseminating protocols.. Anything less than quality herd management dramatically reduces your reproductive performance and profitability. It almost goes without saying that you must choose healthy, normally cycling, well-grown, stress free virgin heifers for breeding with sexed semen. The almost is used because this step has been overlooked to the detriment of a quality outcome. Once the recipient is identified, you must establish the best possible nutritional program supported by clean housing and stringent health protocols. With these in place, you are ready to use the sexed semen. This too must be done properly to prevent lowering the conception rates below those achieved with conventional semen. The following four steps must be completed with scrupulous attention to detail:. ...
The mind is a powerful thing. In this study, the authors find that life stressors have a negative impact sperm concentration, motility, and morphology, however work stressors do not have any relationship. Being unemployed, however, also had a negative impact on sperm quality. Stress is a very subjective feeling, and one persons stress tolerance is different from anothers. How this impacts sperm production may reside in the hormonal milieu that results in ones stress response. I am unsure, however, why different types of stressors would have different impact on sperm quality as found in this study. I see many men that develop erectile/sexual dysfunction as they go through the stress of fertility evaluation and subsequent treatment. This may also explain why I see men in my practice with worsening serial semen analyses as they proceed through the ART process with their partners and once they are finished or pregnancy is achieved, things seem to improve spontaneously without any treatment or ...
The Zika virus has been detected in the semen of a man six months after the onset of infection.. Researchers from the Spallanzani Institute for Infectious Diseases in Rome first detected the virus in the urine, saliva and semen of an Italian man who had been visiting Haiti, 91 days after the first symptoms had been observed. Further testing showed that it remained present in his semen at 134 days and was still detectable at day 181. The researchers explain that the finding confirms that the virus can replicate in the male genital tract and presents a prolonged potential risk for sexual transmission than was previously thought.. The longest period that the Zika virus has been detected in semen after the onset of infection was previously reported as 93 days, in a 27-year old French man. Current guidelines by Public Health England (see BioNews 840) recommend that men infected with the Zika virus should practice safe sex using condoms for six months. The Human Fertilisation and Embryology ...
Carlsen and coworkers (1992) reviewed 61 heterogeneous observational studies on semen quality published between 1938 and 1990. This review indicates that mean sperm density decreased significantly between 1940 and 1990. An extended meta-analysis with 101 studies confirmed a decline in sperm density for the period from 1934 to 1996 (2000). The key message of the meta-analyses is that sperm counts have decreased globally by about 50% over the past decades. This assessment has been questioned. A major methodological problem of the meta-analysis is the use of data collected in different countries, at different times, on different populations and with different methods of semen analysis. Furthermore, the results of studies concerning semen analysis are frequently biased e.g. by selection criteria of volunteers. In most studies on human semen characteristics the populations under study are insufficiently defined and the study participants are not a representative population sample.

THE PERTH GROUP RESPOND TO DAVID CROWES ABYSMAL IGNORANCE CONCERNING SEMEN AND AIDS AGAIN. On 12 January 2010 Rethinking AIDS president David Crowe wrote to Sabine Kalitzkus, copying me in:. One of the first things that I did when I received some claims about semen and HIV/AIDS from the Perth Group related to The AIDS Trap was to obtain and read some of the original papers. I then discovered that these papers did not support their thesis. In fact, I dont know of a single paper that shows that semen alone is associated with AIDS. In fact, I dont know how you could have such evidence because while semen and AIDS are clearly often associated, there are not associated alone, there are usually other practices such as drug use, douching or, as youve pointed out, fisting. Clearly the drug-AIDS hypothesis has more evidence than the semen-AIDS hypothesis and is more plausible.. Besides, most of the evidence provided to me was of an association between semen and HIV seropositivity, not AIDS, which ...
