Too much TV could lower sperm count

Semen quality is a much-discussed subject among scientists these days. Data suggests sperm concentration has been declining in Western countries over the past couple of decades - and reasons for the decline are debatable.

The lead author of a new study on the subject, Audrey Gaskins, has been studying the effects of diet and exercise on semen for several years as a doctoral candidate at the Harvard School of Public Health. Her latest research shows a lack of physical activity ? and too much time in front of the television - may impact sperm count and concentration.

Previous studies have shown a link between physical activity and decreased levels of oxidative stress, Gaskins says. ?Oxidative stress? is stress placed on the body as it tries to get rid of free radicals or repair the damage caused by them. Exercise may protect certain male cells from oxidative damage, Gaskins says, leading to increased sperm concentration.

Men who did moderate to vigorous exercise 15 hours or more per week had a significantly higher sperm concentration than those who worked out less than five hours a week. And the men who watched more than 20 hours of TV a week had almost half the sperm concentration as the men who watched zero hours a week.

Those findings led Gaskins to complete an observational study on young men?s exercise and TV habits as they relate to semen quality. The results were published online Monday in the British Journal of Sports Medicine.

And what is the reason ?

Spermatozoons all decide to colectively kill themselves after realising TV shows are now for the most part crap and the good ones get axed after one season ?

My bet: overheating.

The testicles have to be kept at a lower than body temperature for sperm development to progress normally, which is why men have a scrotum instead of internalizing them.

It's possible that sitting on a foam & fabric cushion for hours at a time not only presses the testicles closer to the body but it also insulates them, raising their internal temperature. Not good as regards sperm development.

My $0.02.

Radiation emitting from old CRT TVs'.

Also contributing factors are TV Channels such as MTV, E! & SyFy too name a few, with TV shows like Jersey Shore and Keeping up with the Kardashians along with non stop WWE Wrestling.

have been known to also reduced Testosterone levels in adolescent males.

Everyone who is concerned about sperm count should watch this documentary by CBC:

And what is the reason ?

A male body needs testosterone to produce sperm.

Testosterone is derived from cholesterol. The primary source for cholesterol is meat/fish.

In order for the body to convert cholesterol to testosterone, our muscles need to be working - we must be walking, running, jumping - doing all sorts of physical activities to stay healthy.

Accordingly, seating on a couch in front of a TV gives zero work to our muscles => testosterone isn't produced => sperm count is lowered.

My bet: overheating.

The testicles have to be kept at a lower than body temperature for sperm development to progress normally, which is why men have a scrotum instead of internalizing them.

You are right. Wearing tight jeans is another hazard for the males because of the testicular overheating.

    • Bypassed Windows 11 shows surprising stability on ancient, completely unsupported hardware

      By +Warwagon · Posted

      With the current hardware prices Microsoft should lift the restriction. Then if you have the correct TPM then allow you to use X feature, if you don't have the correct TPM then don't but still actually let you run windows. 11. With a disclaimer during install that X features would be unavailable.

      It's good for recycling of course. But commence inflation of a second hand RAM bubble and price gouging on DDR 4 inventory in 3... 2... 1...

      Bypassed Windows 11 shows surprising stability on ancient, completely unsupported hardware by Sayan Sen When Windows 11 was first released, one of the most complained-about issues with the new desktop Microsoft OS was its higher system requirements, which pushed many relatively modern and powerful processors and devices onto the officially unsupported list. Thankfully, they have not been updated again for the base OS, though systems require four times the memory and storage if they want to run AI-powered apps and features. As such, Windows 11 technically runs on 4GB of memory, and there is no imposed restriction on the generation of memory it supports. Speaking of memory, prices are extremely high nowadays for hardware, especially DDR5 and DDR4 kits due to the current silicon shortage, and there are also reports of it affecting DDR2 as well, and it might only be a matter of time before even DDR1 gets affected. Before that could happen, an enthusiast took an ancient DDR1-based system and decided to try out Windows 11 on it to see how well the modern OS would fare on such hardware. The system runs an outdated graphics card interface standard based on AGP, or Advanced Graphics Port, called AGP 3.0 or AGP8x. AGP was essentially succeeded by the modern PCI Express (PCIe) bus standard. The user behind the experiment is retro hardware enthusiast Omores, who built the system around an ASRock ConRoe865PE motherboard based on Intel's i865PE chipset from way back in 2003, around the time when AGP was still in fashion. What made this board special back in the day was its unusual support for newer Core 2 Duo and even Core 2 Quad processors while still retaining older DDR1 memory support and an AGP8X graphics slot, making it an ideal bridge or link between two vastly different generations. Powering the machine was Intel's Core 2 Quad Q6600 alongside 3GB of DDR1 RAM and an ATI Radeon HD 4650 AGP graphics card, one of the final and most capable GPUs released for the aging AGP interface. While installing Windows 11 itself was relatively easy by bypassing Microsoft's hardware checks, getting the graphics card fully functional proved to be some challenge. Microsoft had quietly dropped native AGP support after the earliest releases of Windows 10, meaning newer versions of Windows no longer include the necessary Graphics Address Remapping Table (GART) drivers required for proper AGP acceleration. Without them, AGP graphics cards typically boot up, though with limited functionality, and can often throw a Code 43 error in Device Manager. To work around the limitation, Omores extracted Intel's legacy AGP440 SYS driver from an early Windows 10 release and paired it with a modified INF file so Windows 11 would correctly recognize the chipset. Following this and combined with AMD's final 64-bit Catalyst AGP drivers from 2012, the Radeon HD 4650 was able to operate with full AGP 8X acceleration intact. The result was said to be surprisingly usable for hardware that is over two decades old. Hardware-accelerated H.264 video playback worked correctly and benefited apps like Firefox, while legacy applications and games ran without major graphical issues. The system also successfully completed the 3DMark 2001 benchmark, although performance naturally lagged behind what the same hardware achieves under Windows 7, which is significantly lighter than Windows 11. There was, however, one unavoidable limitation as Microsoft's Windows 11 version 24H2 introduces a mandatory SSE4.2 CPU instruction requirement that cannot be bypassed through installer modifications or registry tweaks. Since no AGP-era processor supports SSE4.2, Windows 11 version 23H2 effectively becomes the final release capable of running on such systems. Regardless, it is still a very cool feat and quite fascinating to see just how stable Windows 11 turned out to be on such unfamiliar hardware. Source: Omores (Patreon) via O_MORES (Reddit)

      That will only really help other players that are also responsible for creating the problem.

      Well, it's good to know that they have found a workaround to a problem that they helped create, I guess...
