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 ...

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 ...
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. ...
TY - JOUR. T1 - Correlation between sperm morphology using strict criteria in original semen and swim-up inseminate and human in vitro fertilization. AU - Yang, Y. S.. AU - Chen, S. U.. AU - Ho, H.

N2 - To study the value of sperm morphology using strict criteria in raw semen and in swim-up inseminate of human in vitro fertilization (IVF), 135 cycles of IVF with normal sperm concentration and motility were recruited. 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 ...
Effects of extenders on the quality and fertility of cooled Formosan sambar stag semen after artificial insemination Chih-Hua Wang, Hsin-Hung Lin, Shann-Ren Kang, Ching-Yun Kuo, Wen-Lin Song, Chin-Hui Tseng, Mu-Jung Cheng, Bing-Tsan Liu, and Perng-Chih Shen. 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. The VIAB (TCY: 86.8 vs. 89.3%; TY: 88.1 vs. 92.1%; CY: 84.2 vs. 88.3%) and acrosomal integrity (NAR) (TCY: 82.3 vs. 86.5%; TY: 82.5 vs. 88.5%; CY: 77.3 vs. 85.4%) of the semen diluted with ...

Lots of men throughout the world are suffering from the problems of leaking semen in urine, semen leakage problem. But most of them get embarrassed to discuss the problem with the others. So, they do not go any health experts or do not treat the problem properly. As a result, the problem become more complicated and creates several health crises.. However, the health experts also suggest that the problems related to the sexual health of a person should not be ignored. In addition to, it must be treated as early as possible to stay away from additional complications. Apart from health issues, leaking semen in urine, semen leakage problem can lead to relationships troubles.. Causes of leaking semen in urine or leakage problem When semen leak out after or before urine without any kind of sexual erection or sexual stimulation is called as leakage problem. It creates several depressing effects on the individuals self-worth or self confidence. The possible causes of this particular health problem ...
Semen analysis. This is a very important test for the male partner. Your doctor may ask for one or more semen specimens.

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

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 ...

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.

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 ...
Appendix 1: Hippocrates And Semen Production. Some critics have not stopped at claiming an error in the Quran, some have gone as far to claim that the Quranic description is actually copied from the Greek physician Hippocrates. In order to see if there claims are true let us analyse what Hippocrates taught on semen production.. Hippocrates details his views on semen production in his two works "On Generation" and "On The Nature Of The Child". In his treatise "On Generation" he writes:. 1. 1) All things are governed by law. The sperm of the human male comes from all the humour in the body: it consists of the most potent part of this fluid, which is secreted from the rest. The evidence that it is the most potent part which is secreted is the fact that even though the actual amount we emit in intercourse is very small, we are weakened by its loss. What happens is this: there are veins and nerves which extend from every part of the body to the penis. When as the result of gentle friction these ...
A bigger semen volume is desirable for many men - for the guys who want to increase their chances of getting a partner pregnant, the ones that would like to experience the ultimate orgasm and those who simply link a bigger load to manliness. Some guys, however, take semen volume for granted and they think that nothing
In clinical practice, there are often patients with diyi results that are not very good, so they are somewhat negative, thinking that their fertility is not good. In fact, doctors usually need to pass at least two semen examination reports before they can judge whether the patients fertility is normal. At this time, the patient may want to ask, why does the result of each semen test be different? Why does the routine semen test need to be checked 2-3 times? The routine semen test results will be different each time The main reason and semen analysis The method is related, but also related to the patients own physical condition. 1. The abstinence time of semen examination The number of abstinence days before semen test has an effect on the results of semen examination, especially on the amount of semen and the number of sperm. If the interval of sperm discharge is too short, the amount of semen and sperm will be reduced, which cannot truly reflect the fertility of men. However, if the interval ...
We used a staggered sampling approach in which semen samples were produced by participants over several days at different sampling times relative to the morning dose of antiretrovirals. Speci﫿- cally, semen samples were collected 30 minutes to 1 hour before the morning dose of medication (day 1), and then at hours 1, 2, 4, 8, and 12 postdrug ingestion on days 2-6. We collected corresponding blood samples within 1 hour of the semen sample. For each participant a single value (the HIV concentration ratio) was calculated as the minimum HIV concentration in the semen over the minimum HIV concentration in the blood throughout the dosing interval ...
