DESCRIPTION: A lot of men have asked if frequent masturbation lowers sperm count or their fertility.

Belinskii: So she's basically an INTJ

Z Cross: So, seen as equal, punctual and accurately, intelligent and politically informed, honest, show when they love you. german woman come off well in this list ^^

Lynn Janssen: What about an African man?

Donalf C.m.a: You forgot the most important one, she has a mustache

TheZnjora: That was the most truthful video on Russian men! Russia is an extremely conservative and traditional country. I personally can't imagine what does it mean not to take care of your woman, not paying for her and not protecting her. Such behavior here is considered to be too feminine and Russian women really get offended when their men doesn't show care in such a radical way

Caroline Nz: I saw so hot german girl in crete but never probably going to see her again :/

Tommy Hopps: Dutch men act pretty similar to German men. I guess these men misunderstood the concept of treat a woman as your equal;)

Rubikari: Why do all of these silly videos just consist of cliche? I dont get it why cant they just make a Video that is actually accurate?

Patrick Gomes: Yep. We fuck each other before we decide whether or not we should be in a relationship. That's how we danes roll.

Ajan Navarro: She is beautiful!

Leah Yuriko: And the Croatian one is amazing. Tho a lot depends on the way of speaking, not exactly language I think. F.ex. this Serbian lady didn't really catch me until she went with this dreamy sexy 'Volim te :'D

Robert Torres: This is pretty similar to dating a Persian girl :D

Rahul Mehta: Wow, I thought this video was fairly shit after watching the entire thing with annoying as fuck female laughter right by the camera, but now looking through the comments half of which are native speakers to the languages in the videos saying they can't understand 50 of what was said I have come to the realization that I just wasted almost minutes of my life.

LyricZombie: You know you're dating a Ukrainian woman.

Junior Dias: I'm a native French married with a russian woman from Kazakhstan. How true your video is. My beloved woman would never go out without being well dressed and makeup, even to go to the recyling place to empty big broken stuff and come back with a full trailor of compost.

Jesus Paul: Can you do sth korean guys? :')

Da Hulk: I am from Germany but I am doing an exchange year in the US right now. I have to say that I completely agree with these points! :)

Xhindi Vant: Well, this video certainly portraits me pretty well, so, well done!

EJ Estonactoc: Very fun video. As always, it was well done. I had a short relationship with a Ukrainian girl once. We were traveling in central Europe and she thought it was strange that my luggage was red because she felt red was a woman's color.

Laura Jarillo: What about dating an Ecuadorian man?

K B1999: I must not be an English woman then.

Filip Selino: This video is too funny, these women are not really saying what they feel. This is fun short term stuff ;)

Tina Lester: OK, no Finn man for me, kiitos, hei.

Alan Nunes: All the video said was that French women complain non-stop and will frustrate you. Wasn't there anything positive?

Diogo Penna: I find Spanish, French, Greek, German, English (U.K. sexy. Also I find a southern us accent sexy.

Tom Roulston: Wait was the french speaking girl actually french cause im french and that did not sound right

Ado Nurko: She looks 20 years older than the guy.

Freya Thomas: Chileno qliao fome xd



Introduction

15 Jul Learn how certain medications, your age & frequent ejaculation can also affect male ejaculate. Most of the sperm-containing fluid released through the ejaculatory duct comes from the seminal vesicles, two glands near the prostate, and the Low T can also result in the production of less seminal fluid. 2 Jul "These results may mean that men play a greater role in infertility than previously suspected, and that ejaculatory frequency is important for improving sperm quality, especially as men age and during assisted reproduction cycles," he said. Men are usually advised to abstain from ejaculation so sperm count. 30 Jun The men were instructed to ejaculate daily for seven days, and no other treatment or lifestyle changes were suggested. Before they started, levels of DNA damage ranged between 15% and 98% DFI, with an average 34% DFI when measured after three days' abstinence. When the men's sperm was.

Several factors have been shown to influence semen parameters, one of which is sexual abstinence; a clinical criteria included in the semen evaluation to provide maximum sperm quality. The aim of the present study was to assess the effect of a daily ejaculation frequency on conventional and functional semen parameters.

Semen samples were Sperm count of the daily ejaculator daily over a period of two weeks of which every second sample per person was processed and analyzed according to the World Health Organization guidelines.

Furthermore, mitochondrial function, intracellular reactive oxygen Sperm count of the daily ejaculator production and sperm DNA fragmentation were evaluated by flow cytometry. Total sperm count and seminal volume per ejaculation declined and remained decreased for the duration of the daily ejaculation period. However, conventional parameters such as sperm concentration, motility, progressive motility, morphology, vitality and functional parameters such as sperm plasma membrane integrity, mitochondrial membrane potential and DNA fragmentation was not significantly affected and remained similar to the initial measurement throughout the daily ejaculation period.

Despite intra- and inter individual variations, the average values of the basic semen parameters remained above the WHO reference values throughout the daily ejaculation period. Interestingly, a decreasing trend in intracellular ROS production was observed, although statistically not significant. Once human spermatozoa have been produced in the seminiferous tubuli, they are stored in the epididymis for future release [ 1 ].

Unlike other species, the male gamete of mammals must pass through the epididymis, where they undergo a series of physiological and biochemical changes, allowing them to mature and acquire fertilizing potential [ 1 ].

The variation is probably due to the Sperm count of the daily ejaculator of passage through the cauda which in turn can be influenced by ejaculatory frequency [ 34 ]. The negative effect of prolonged storage epididymal transit on Sperm count of the daily ejaculator motility has been reported widely, but the effective storage period in the human is still uncertain [ 35 ].

More recently new insights have been gained through the research conducted on epididymal function and its regulation of spermatozoa [ 6 — 8 ]. The World Health Organization Sperm count of the daily ejaculator guidelines recommend an abstinence period of 2—7 days prior to semen collection for standard seminal evaluation [ 9 ]. The impact of sexual abstinence on conventional sperm parameters is still controversial [ 1112 ].

There is general agreement that semen volume and sperm concentration will increase with prolonged sexual abstinence, but simultaneously it can have a negative impact on sperm motility and viability [ 13 — 15 ].

Some other authors have suggested that spermatozoa are greatly exposed to reactive oxygen and nitrogen species ROS and RNS during epididymal maturation and storage [ 1617 ].

Spermatozoa are extremely susceptible to oxidative attack and this has been well-correlated with decreased sperm motility, lipid peroxidation, DNA damage and impaired fertilization rates [ 18 — 21 ].

The search for a cost effective fertility treatment has been important to optimize the likelihood of achieving pregnancy. It has been proposed that recurrent ejaculations [ 22 ] could be an approach to improve sperm DNA quality and therefore reproductive outcome [ 1112 ]. The aim of the present Sperm count of the daily ejaculator was to assess the effect of daily ejaculation DE for 2 consecutive weeks on conventional semen parameters as well as the physiological sperm characteristics such as mitochondrial function, intracellular ROS production and sperm DNA fragmentation index DFI as further indicators of sperm production quality and the implication for fertility treatment.

Ethical approval for this study was obtained from the institutional Research Ethics Committee, and all men provided informed consent. This study used semen samples collected between May and July Six healthy men In addition, self-reported illnesses or use of medication in the three month immediately preceding the study. For Sperm count of the daily ejaculator first evaluation, a 3—4 day period of sexual abstinence was required and all samples were classified as normozoospermic.

The volunteers did not Sperm count of the daily ejaculator any medications and were sexually inactive during the two week DE period. Sperm morphology was analyzed according to the Tygerberg Strict Criteria [ 23 ], while the concentration was determined using a Makler chamber Sefi-Medical Instruments, Haifa, Israel [ 24 ].

It is therefore useful for the detection of ROS and nitric oxide NO and for the determination of the degree of overall oxidative stress [ 25 ]. Results are expressed as the mean fluorescence intensity MFI of live Sperm count of the daily ejaculator exhibiting a fluorescent response.

Sperm count of the daily ejaculator is a cell-permeant, green-fluorescent cationic Sperm count of the daily ejaculator dye that is selective for the mitochondria of live cells when used at low concentrations. PI was used as a vitality counter stain. Samples were scored as the percentage cells in Sperm count of the daily ejaculator population showing high MMP.

Forward scatter and side scatter measurements were taken to generate a density plot, which was used to gate for sperm cells only.

All data were acquired and analyzed using WinMDI 2. To compare the variables between groups without assuming that values follow a Gaussian distribution the non-parametric Mann—Whitney test was used. Data were analyzed using Prism 5. As expected, seminal volume were reduced during the DE period. These observations were already manifested on Day 2. However, a wide intra-individual variation was observed in each of these parameters.

The subtle changes in motility and sperm viability are worth noting, with the number of viable spermatozoa actually increasing on day 13 of the experiment compared to the initial evaluation All of these basic parameters furthermore remained above the WHO reference values throughout the DE period except for the viability on day 4 None of the functional parameters were significantly influenced by two weeks of DE. The percentage of DNA fragmentation did not differ significantly from the initial measurement.

With regards to the production of intracellular ROS, a trend of reduction Sperm count of the daily ejaculator observed over time statistically not significant. The intra and inter individual variation of both the conventional and functional seminal parameter over Sperm count of the daily ejaculator DE period are depicted in Figs. Studies have found that human semen samples vary over time and this may be due to three principal factors: The search for predictors of male fertility has resulted in the standardization of procedures for the examination of human semen; an example of this is the guidelines developed by WHO to process seminal samples based on global demographic population Sperm count of the daily ejaculator [ 9 ].

This effort has made a solid contribution to semen analysis and has provided a better understanding of human sperm quality. In the present study, we found that daily ejaculation had an effect on some conventional and functional semen parameters.

This evidence is in accordance to findings from other studies where it was also reported that reduced sexual abstinence had an impact on sperm count and seminal plasma contribution [ 1532 ]. However, a decrease, although statistically not significant, in intracellular ROS production was observed as early as the second day of high ejaculation frequency and these levels were maintained well below that of the first evaluation MFI: It has been well described in studies of ROS production and sperm physiology that these highly reactive chemical species play a major role in many sperm processes such as maturation, motility and capacitation [ 33 ].

Nevertheless, the ROS levels must be controlled within physiological levels as overproduction or lack of sufficient antioxidant systems can lead to the development of oxidative stress. As these compounds are highly reactive they can cause lipid peroxidation, DNA damage and apoptosis which impacts directly on both conventional as well as functional sperm parameters [ 21 ].

We observed that during periods of high ejaculation frequency the sperm concentration initially decrease, but then remained within the same range for the remainder of the DE period, similar results have been previously reported [ 34 ].

The initial total sperm count was substantially higher and that can be ascribed to the fact that reserves were available and stored in the epididymis. Due to the increased ejaculation frequency the reserves were depleted and total sperm count decreased, these decreased levels of sperm count can be perceived as the daily spermatogenic production.

There are several factors that may influence spermatogenesis including metabolic, genetic, environmental and physiological factors. More than likely, the increased daily spermatogenesis, greater epididymal sperm storage and more sperm in the ejaculate is resultant of evolutionary processes due to sperm competition in mammals and some other species [ 35 — 38 ].

Borgerhoff Mulder, on the other hand supports another idea which hypothesize that the human species adopted a reproductive strategy of high-investment and low-fertility during gamete production [ 39 ]. ROS are ubiquitous in life and death processes of cells and is a key player in intracellular signaling, host defense, cell death and adaptation processes [ 4041 ].

The reduction in intracellular ROS levels may underline the role of epididymal function and the time spent in the epididymis; some authors have proposed that spermatozoa are greatly exposed to ROS and RNS during epididymal transit and storage [ 11 ].

The increase in sperm viability towards the end of the DE period can probably be related to the decreased ROS levels as the spermatozoa would subsequently be less exposed to lipid peroxidation or apoptosis. Likewise, the role of ROS in relation to normal sperm physiology and senescence must be addressed in future studies, specifically investigating the effect on capacitation and the acrosome reaction.

It can therefore be deducted that prolonged sexual abstinence periods can have a detrimental effect on sperm function and could affect sperm quality [ 14 ]. Further studies are required to determine if low antioxidant activity and high oxidative stress in the epididymis itself are associated with poor fertility [ 16 ] and to determine the relation between abstinence and sperm conventional and functional characteristics. The DNA integrity of spermatozoa has been considered as an important parameter in fertility studies [ 2526284243 ].

Similar studies have shown that Sperm count of the daily ejaculator abstinence periods lead to a greater reduction in the incidence of sperm DNA fragmentation and an increase on pregnancy rates after assisted reproductive techniques [ 1112 ]. During the whole process of spermatogenesis and maturation, the nuclear content gets condensed through a process whereby histones are replaced by protamines. This helps to protect the chromatin in the head of the spermatozoon.

It is argued that an extended DE period i. This will have a negative influence on the chromatin quality and can be associated with immature nuclear spermatozoa which are highly susceptible to DNA fragmentation. To summarize, our results show that semen variables such as semen volume and total sperm count show a decrease when it is compared to the initial sample.

However, parameters like progressive motility, morphology, MMP, DFI and plasma membrane integrity remain similar to the initial evaluation while others such as viability and ROS levels showed some improvement towards the end of the tested DE period. In conclusion, our data suggests that frequent daily ejaculation of two weeks have no major negative effect on both conventional and functional parameters.

The implication of this is extremely relevant clinically as it means that men diagnosed with cancer can collect and bank several semen samples in quick succession prior to onset of chemotherapy.

Furthermore, frequent daily ejaculations can be utilized as a treatment option in cases of male infertility problems related to oxidative stress. All authors read and approved the final manuscript.

They also show that long periods of abstinence can impact.

Delegates at a fertility association have heard that continuously ejaculation or daily femininity may be the greatest way to improve sperm quality and could besides the chances of reach pregnant. David Greening starting Sydney IVF says a study they have conducted suggests that for men with fertility problems, always ejaculation for a week reduced the amount of DNA damage in sperm samples.

At the European Society for Human Duplicate and Embryology in Amsterdam the Australian fertility artist said in general communication for couples had unfashionable to have sex now and again two or three existence but Dr.

Greening an obstetrician and endrocrinologist says men seeking to fit a father should must sex each day, or else ejaculate daily, for a week before their husband ovulates in order in the direction of maximise sperm quality. In spite of that while fourth-fifths of the men saw an surge in sperm quality, also many of them moved into the "good" migrate and out of the "poor" or "fair" categories, one-fifth saw a run out of gas in sperm quality.

Greening says the improvements were "substantial and statistically exceptionally significant" and that diurnal ejaculation not only boosted sperm quality for lion's share of the men, it also helped sperm motility, another big factor in vogue successful fertilisation - uninterrupted though the volume of semen declined. Though the research did not explore whether the improvement inwards sperm quality led headed for better pregnancy rates, prior research has shown with the intention of sperm that is shortened damaged and more versatile has a better possibility of leading to a healthy baby.

Timed and frequent intercourse around the time of female ovulation is recommended to improve conception. Although a significant number of articles have examined how the length of abstinence affects these semen analysis, the effects of frequent daily ejaculation has not been rigorously studied. Twenty normal men were recruited for daily ejaculation over 14 consecutive days, after a 3—5 days abstinence period. Semen samples were collected at the beginning of the study day 1 and then on days 3, 7 and In addition to the standard semen analysis, markers of sperm DNA quality were assessed.

The mean age of men completing the study was 25 years range, 23—33 years. Significant decreases were observed in mean semen volume, total motile count TMC and sperm concentration during the study period without significant changes in motility or morphology.

A large initial change in ejaculate volume, TMC and sperm concentration provided the primary difference in these values over the study period, with a plateau in values after this initial decrease after study day 3. Metrics of DNA integrity did not change in a statistically or clinically meaningful way during the study period.

While a small study, this represents the most extensive examination of sperm quality with daily ejaculation.

MEN seeking to become a dad should have sex each day for a week before their partner ovulates to improve the genetic quality of their sperm, new Australian research suggests. Until now fertility specialists have debated whether refraining from sex in the days before attempting to conceive with their partner could increase a man's chances of fathering a child.

A study by David Greening, a specialist in reproductive endocrinology and infertility at Sydney IVF, has found that ejaculat ing daily substantially improves the genetic quality of sperm, without lowering sperm counts enough to impair fertility. At the annual meeting of the European Society of Human Reproduction and Embryology in Amsterdam this week, Dr Greening said the findings could have important implications for couples trying to conceive spontaneously and those undergoing assisted reproduction.

Men are usually advised to abstain from ejaculation so sperm count has time to recover before the woman's most fertile period or egg retrieval in the case of IVF. Dr Greening studied men with above-average sperm DNA damage and found their sperm quality increased significantly after they were told to ejaculate daily for seven days, compared to three days abstinence.

On average, their DNA fragmentation index - a measure of sperm damage - fell from 34 per cent poor quality to 26 per cent fair. Ninety-six men recorded about 12 per cent decrease in sperm DNA damage, putting them in the good range. Dr Greening said it was likely frequent ejaculation improved the quality of sperm by reducing the length of time they were exposed to potentially damaging molecules called reactive oxygen species in the testicular ducts and epididymis.

Await now readily available has square no evidence-based consensus between fertility specialists as near whether or else not men should exhortation from bonking for a few existence before attempting to envisage with their partner, whichever spontaneously otherwise via assisted reproduction. Dr David Greening, an obstetrician and gynaecologist with secondary specialist keep fit in reproductive endocrinology after that infertility by the side of Sydney IVF, Wollongong, Australia, said: The men were instructed towards ejaculate each day for seven days, along with no previous treatment or else lifestyle changes were suggested.

These changes were significant and statistically highly historic. It seems safe in the direction of conclude to couples as well as relatively standard semen swing should would rather sex each day for positive to a week in the past the ovulation date. Stylish the setting of assisted reproduction, that simple care may support in improving sperm supremacy and at bottom achieving a pregnancy. Arrive addition, these results might mean so as to men act a stress a better role in the sphere of infertility than previously suspected, and to ejaculatory concretion is primary for improving sperm importance, especially so men become old and amid assisted imitation cycles.

Dr Greening believe he solicitude recollections the reckon why sperm quality improved with repeated ejaculation was because the sperm had a shorter exposure here the testicular ducts furthermore epididymis en route for reactive oxygen species - very little molecules, maximum levels of which be able to damage cells.

No one questions why people are straight because that's how we procreate there's ENORMOUS evolutionary selection pressure to be straight. Not-LGBTQ-ness in general is evolutionarily favorable, and so it is an interesting question how LGBTQ-ness arises from a scientific standpoint. This has nothing to do with people's personal stories it's about answering the unknown, about conducting science.
