DR MICHAEL MOSLEY: Why biking and hayfever tablets may be unhealthy information for a person’s love life

As a eager bicycle owner I learn with curiosity — and a few alarm — analysis from Poland this week suggesting that male cyclists are prone to erectile issues and presumably infertility.

The issue is that driving a motorbike can put strain on the Alcock canal (sure, that basically is its identify), part of the male anatomy that incorporates nerves and arteries that feed the genital space, inflicting lack of sensation and different issues.

Using a motorbike may also result in native atherosclerosis, a thickening of the arteries that would, in the long run, scale back the blood provide to this valuable organ, based on the Boston College of Sexual Drugs.

That is no small difficulty — the quantity of people that cycle is rising. In response to the charity Biking UK, in 2018, 11 per cent of UK adults cycled a minimum of as soon as per week, rising to twenty per cent (practically 11 million) in 2020. And surveys recommend the nice majority of them are males, though this hole is narrowing.

So how actual are the dangers? Properly, there’s excellent news and unhealthy information.

The problem is that riding a bike can put pressure on the Alcock canal (yes, that really is its name), a part of the male anatomy that contains nerves and arteries that feed the genital area, causing loss of sensation and other problems

When researchers from the New England Analysis Institutes requested greater than 1,700 American males about their biking habits, they discovered that males who cycled for lower than three hours per week (that’s me), not solely didn’t have an issue, however that modest ranges of biking gave the impression to be positively good for his or her intercourse lives, with 40 per cent much less probability of affected by erectile dysfunction than those that by no means cycle. Hurrah!

The information wasn’t so nice for eager cyclists, who had been 70 per cent extra doubtless than non-cyclists to have reasonable or extreme erectile dysfunction.

It’s not simply males — with ladies, there’s some proof that a number of time spent within the saddle can result in issues similar to urinary tract infections, although not any apparent adverse impression on their intercourse lives.

(Within the meantime, my middle-aged male buddies who’re enthusiastic cyclists all advocate switching to saddles with a shorter ‘nostril’, or ideally none in any respect.)

To be honest, though erectile dysfunction is a standard and distressing situation for males, biking isn’t up there as a number one trigger.

Neither is sporting tight trousers, regardless of the favored perception that it’s. Sure, in case you put on very tight trousers for lengthy intervals of time then you definately would possibly scale back the blood provide to your important components, however I can’t discover any particular analysis on this, and it doesn’t appear to have slowed down Sir Mick Jagger. 

Most circumstances of erectile dysfunction are literally attributable to smoking (which doubles your danger), hypertension (which additionally doubles your danger), extreme ingesting, being obese and stress — all not directly affecting blood circulation, nerve sensitivity and or hormones similar to testosterone.

So the plain reply, if in case you have erectile issues (or want to forestall them) is to quit smoking, drop extra pounds, drink much less, scale back your blood strain and attempt to handle your stress.

Different issues that assist embody consuming a Mediterranean-style food regimen, flossing your enamel and avoiding sure medicines, similar to antihistamines (for allergy symptoms) and nasal decongestants (particularly those who comprise pseudoephedrine). Proof for the advantages of the Mediterranean-style food regimen comes from a examine of 250 Greek males with hypertension, carried out by the College of Athens in 2021. 

They confirmed that the lads who ate a food regimen wealthy in fish, nuts, fruit, greens and olive oil, not solely had larger testosterone ranges and more healthy blood vessels but additionally higher erectile efficiency (the latter assessed utilizing the Sexual Well being Stock for Males, primarily a questionnaire).

The researchers suppose a Mediterranean-style food regimen improves blood circulation and maintains wholesome testosterone ranges.

As for flossing, based on a 2018 examine by Jinan College in China, males with gum illness are practically 3 times as prone to undergo from impotence as these with more healthy gums. One principle is that gum illness can result in widespread irritation which damages blood vessels all through your physique, together with your mind.

And medicines that comprise antihistamines or pseudoephedrine? These medicines are widespread presently of yr for folks with hay fever or blocked up noses, however they will even have a short-term impression on male intercourse drive.

That’s as a result of antihistamines work by blocking the motion of histamine, a chemical discovered within the cells that causes allergy signs — however histamine can also be essential for wholesome erections; whereas pseudoephedrine could cause blood vessel constriction.

These are simply a few of a protracted record of medicines that may trigger impotence issues; in case you are involved, focus on this together with your GP.

In the meantime one other factor male cyclists ought to notice: biking could cause your ranges of prostate-specific antigen (PSA) to rise within the quick brief time period.

Checking PSA ranges is a method of detecting prostate most cancers and a examine within the journal PLoS One in 2013 discovered that cyclists’ PSA ranges rose by practically 10 per cent after a long-distance experience. The researchers, from the Victorian Institute of Sport in Australia, recommend avoiding biking for twenty-four to 48 hours earlier than a PSA take a look at to keep away from skewing outcomes.

When you have irritable bowel syndrome (IBS), you’ll know that there are few efficient therapies. So a current examine that confirmed a faecal transplant may also help is sweet information.

Right here, donor faeces are screened, then blended with water and inserted into the heart of a affected person through a colonoscopy.

This successfully parachutes a military of wholesome intestine microbes into the affected person’s massive gut, to fight any nasties there. It really works extremely effectively with C. difficile infections (which might trigger diarrhoea, fever and belly ache) — and now it’s been proven to assist with IBS.

Analysis, from the Stord Hospital in Norway, confirmed that three years after their transplants, most sufferers had been considerably higher, with far much less ache and a a lot improved high quality of life.

It appears that evidently poo actually is a remedy we are able to’t sniff at.

Llamas are fantastic, pleasant creatures, and had been revered by the Incas, who relied on them for wool, transport, meals and even gas (their dung).

And llamas have come up trumps once more; researchers on the College of Pittsburgh discovered that after a Covid an infection, a llama known as Wally started producing highly effective proteins (known as nanobodies) that neutralised all current Covid-19 strains.

These nanobodies may be mass produced, with out llamas, and after human trials the hope is that sufficient may be produced to assist counter future outbreaks.

Is your good cellphone making you dumb?

Keep in mind the olden days if you had to make use of maps to get round, and discovering out info would possibly contain journeys to the library?

It was fairly tedious, however I can’t assist feeling that once we ditched that world we additionally misplaced one thing: we stopped utilizing crucial components of our brains — and that issues.

Subsequent month, A-level, GCSE and diploma outcomes shall be revealed, and it’s extremely doubtless they are going to be excellent.

And but common IQs have been falling for the reason that Seventies. That’s the conclusion of a number of research, together with one in Norway that regarded on the IQ exams taken by 730,000 males between 1970 and 2009 — these born in 1991 scored practically 5 factors decrease than these born in 1975.

Researchers name this ‘the reverse Flynn impact’ — the Flynn impact refers back to the method folks worldwide had performed higher on IQ exams, by a mean of round three factors per decade, from the Forties.

Doable explanations for this embody the truth that within the a long time instantly after World Struggle II, youngsters’s diets grew to become extra nutritious, they spent extra time in class, and because of vaccines, they had been much less susceptible to infectious ailments similar to measles that may have an effect on mind improvement. Now, nonetheless, common IQ scores, in some western nations a minimum of, are falling virtually as quick as they as soon as rose.

The researchers in Norway suppose that is all the way down to youngsters’s diets getting worse (with growing quantities of junk meals) and the rise of the web and good telephones and different know-how, which suggests they don’t have to make use of their brains in the identical method earlier generations did.

If true, it’s clearly very worrying. Good telephones are good bits of know-how, however do put them apart when you’ll be able to and guarantee your youngsters do, too.
