David McCaffrey insists he has by no means been wanting vim and vigour, regardless of a fairly energetic life: a father of three and a busy NHS an infection management nurse, he manages to go to the fitness center not less than 5 instances per week, however says he nonetheless at all times has power to burn.
Or not less than, he used to. As a result of David’s bodily and psychological wellbeing have each lately declined: in addition to turning into severely obese — placing on practically 2st in just some months — he has misplaced his intercourse drive and finds it tough to concentrate on the best of duties.
‘At first, I blamed the burden achieve on the Covid-19 pandemic as a result of the onset of a few of my signs coincided with the primary lockdown in March 2020,’ says David, 47, from Redcar, close to Middlesbrough.
‘The gyms had been closed so I couldn’t get my common train — I used to go not less than 5 instances per week for 45 minutes every time — so I simply assumed that was what led me to placed on a lot weight and brought about the lethargy.

‘And as for my dwindling libido, I put that right down to the truth that in January 2020 my spouse Kelly had undergone main surgical procedure, so intercourse had been out of the query for some time anyway.’
There have been different troubling signs, too. David began getting complications each few days and waking three or 4 instances an evening drenched in sweat.
These, too, he blamed on lockdown-induced lethargy, mixed with the truth that he was simply getting older.
Then in the summertime of 2021, his native fitness center lastly reopened, providing free blood checks to test for potential well being issues comparable to raised ldl cholesterol.
David took up the provide and was shocked when, just a few days later, the clinic that processed the samples referred to as to say he had extraordinarily low ranges of the hormone testosterone and may see a physician as quickly as potential.
‘Kelly and I appeared on-line and noticed a protracted checklist of the signs for testosterone deficiency — together with lack of libido, lethargy, low temper, weight achieve and fatigue,’ says David. ‘Immediately all of it clicked into place.’
He believes testosterone deficiency additionally defined the despair he had skilled since 2016, for which he had been prescribed antidepressants.
It appears he’s removed from alone —in line with some specialists not less than, testosterone deficiency in males, also known as the male menopause, is a big but unrecognised well being burden.
It has been estimated that the testosterone ranges of 40 per cent of males aged over 45 are low sufficient to warrant therapy, studies the American Urological Affiliation.
But regardless of the big variety of males affected, low testosterone as a medical concern has lengthy been uncared for, says the British Society for Sexual Drugs.
That is although treating a deficiency is easy, with three-monthly testosterone injections (normally into the buttocks) or a day by day dose of a gel (rubbed into the pores and skin).
In reality, GP practices in England already spend about £14 million a 12 months on jabs, gels and pores and skin patches for males with hypogonadism, or low testosterone.
However there appears to be a bigger, unmet want, to guage from the surge within the variety of non-public males’s well being clinics now testing and treating low testosterone.

Even Excessive Road pharmacy big Superdrug has acquired in on the act, providing a house check for £50 — males full a web based questionnaire which is reviewed by a physician, earlier than a provide of testosterone gel is despatched within the publish.
Superdrug instructed Good Well being it has had ‘a constant enhance in demand for its male testosterone test-and-treat service’, including that over the previous 12 months, ‘there was a 190 per cent enhance in orders for this service’.
And whereas testosterone, as a prescription drugs, can’t be marketed to customers, there isn’t any bar on selling a service that provides to check a person’s hormone ranges for depleted testosterone.
It appears seductively easy. In its advertising and marketing literature, the newly launched Ted’s Well being scheme says lower than 10 per cent of males with testosterone deficiency at present obtain therapy. It affords testing at residence for £50, adopted by a month-to-month £99 payment for testosterone provides and common blood checks.
One other non-public supplier, Optimale, guarantees ‘high medical doctors, quick, handy prognosis and the highest-rated testosterone alternative remedy from residence’.
The therapy just isn’t low cost —usually costing between £900 and £1,100 a 12 months. However achieve this many males actually need testosterone alternative remedy (TRT)?
Proponents insist it may assist tens of millions extra males within the UK, whereas sceptics concern it’s being over-marketed as an costly cure-all for the ageing course of.
Testosterone, which is produced within the testes, performs a variety of essential roles within the male physique. It drives libido and sperm manufacturing, helps with the manufacture of purple blood cells, maintains bone density and will increase muscle power. It additionally retains reminiscence sharp and helps maintain wholesome blood move from the center.
Wholesome testosterone ranges in males are 12 nmol/l (a measure of how a lot hormone there’s in a litre of blood) or above.
A studying between 8 and 12 is taken into account borderline — whereas any studying beneath 8 is normally outlined as hypogonadism.
As soon as males hit their 30s, their hormone readings begin to tail off at a price of about 1 per cent a 12 months, merely resulting from ageing.
However these numbers don’t inform the complete story — for whereas some males who’ve low ranges of testosterone expertise no signs, others have signs once they seem to have good ranges of testosterone.
So it’s recommended that treating testosterone in isolation could miss the larger downside. Based on some analysis, depleted hormone ranges are far more than only a warning signal that issues could be a bit flat within the bed room.
There appears to be a bigger, unmet want, to guage from the surge within the variety of non-public males’s well being clinics now testing and treating low testosterone
A landmark 2007 research on the College of California at San Diego, which tracked practically 800 males aged over 50, discovered that these with low testosterone scores had been 33 per cent extra susceptible to untimely dying than these with wholesome readings.
Individually, testosterone has additionally been linked to kind 2 diabetes. Final 12 months, researchers in Australia discovered that common injections of the hormone may stop males aged 50 to 74 growing the situation.
The 2-year research, reported in The Lancet Diabetes & Endocrinology, tracked round 1,000 obese males who had been classed as pre-diabetic (i.e. with blood sugar ranges larger than regular).
All the lads had low testosterone and had been signed as much as a wholesome life-style programme to enhance their diets and train routines. Half additionally acquired a testosterone jab each three months, whereas the remainder acquired dummy jabs.
The researchers discovered that the testosterone jabs had a a lot better impression than merely having a more healthy life-style, with simply 12 per cent of the testosterone group growing kind 2, in contrast with 21 per cent within the placebo group.
These on the hormone jabs additionally reported elevated muscle mass, power and improved libido.
TRT — and the broader well being claims made for it — has parallels with hormone alternative remedy (HRT).
But mainstream drugs has but to embrace it to the identical extent, says Dr Anand Patel, a GP in London and a member of the Major Care Testosterone Advisory Group (who’re medical doctors with an curiosity in TRT).
Dr Patel, who treats males with low testosterone on the NHS and privately, says: ‘We settle for the truth that girls become older and need assistance with the menopause, however not with males. But testosterone deficiency is on the rise as individuals are getting fatter.’
It is because fats cells convert testosterone into oestrogen — so the extra fats you may have, the decrease your ‘male’ hormone ranges.
Extra fats additionally reduces ranges of intercourse hormone binding globulin (SHBG), a protein that carries testosterone within the blood to important organs and muscle groups. Much less SHBG additionally means much less circulating testosterone.
‘Normally males current as a result of they’ve been Googling their (typically long-standing) signs on-line and puzzled if it was testosterone deficiency — or their companion has despatched them in,’ says Dr Patel.
‘They typically really feel as if somebody has turned the color down on their life they usually need it again.’
Dr Patel says most NHS and personal GPs prescribing testosterone to males achieve this responsibly: ‘We aren’t dishing it out like sweets,’ he says.
‘To start with, we advise males to undertake life-style adjustments for 3 to 6 months, as shedding physique fats makes testosterone ranges go up.’
However typically, GPs will even concurrently add in a low dose of testosterone remedy from the outset.
‘Many males discover it actually tough to spice up hormone ranges by means of life-style adjustments alone, so we frequently encourage them by additionally placing them on a small quantity of TRT, because it creates a way of wellbeing.’
However he provides: ‘Not all males with typical signs could have testosterone deficiency. They might have thyroid issues or anaemia that are making them really feel unwell.
‘If a affected person has the basic signs — lack of libido, fatigue, weight achieve — however regular testosterone readings, then we’d examine different potential causes.’
So why would these signs happen if a person has regular testosterone ranges?
When testosterone enters any cell within the physique, it latches on to a receptor — triggering the discharge of an enzyme referred to as 5a-reductase.
This enzyme converts the testosterone right into a turbo-charged model referred to as DHT, which is ten instances extra highly effective than the testosterone itself.
However these receptors can fluctuate in sensitivity from one man to a different, which can clarify why some can have blood checks exhibiting they’ve enough hormone ranges circulating however nonetheless really feel unwell.
Nonetheless, TRT just isn’t with out dangers. A 2019 research by McGill College in Canada, involving practically 15,000 males, discovered that these on it for flagging libido had been 21 per cent extra more likely to expertise a coronary heart assault or stroke than these not on it.
It’s not clear why this needs to be so, however one idea was that raised testosterone could injury coronary heart muscle cells or cut back ranges of the so-called ‘good’ ldl cholesterol, HDL, which is believed to guard towards coronary heart illness.
These findings have since been referred to as into query by a serious evaluate in June 2020, involving researchers at Imperial Faculty London, which examined all of the proof to this point and concluded that males on TRT are actually at no better threat of a coronary heart assault or stroke.
Some small research even counsel it has a protecting impact.
But even the world’s main medical authorities can’t fairly make up their minds on security.
In 2015, the U.S. Meals and Drug Administration demanded that testosterone alternative merchandise carry a warning on the label of an elevated threat of blood clots, primarily based on research suggesting a coronary heart threat. However the European Medicines Company concluded that there’s not sufficient proof to point out this.
One other fear is about prostate most cancers. Whereas injections of the hormone are unlikely to trigger prostate most cancers, most prostate most cancers cells do depend on testosterone to develop.
For that reason, sufferers on the therapy ought to have common blood checks for his or her ranges of the protein prostate-specific antigen (PSA), as a rise may point out prostate most cancers.
Dr Channa Jayasena, a marketing consultant in reproductive endocrinology and andrology at Imperial Faculty London and one of many researchers concerned within the 2020 coronary heart illness evaluate, says that despite the fact that TRT seems comparatively secure, ‘it shouldn’t be given indiscriminately’. He instructed Good Well being: ‘There’s a proliferation of personal clinics which might be encouraging widespread use of testosterone — and a small variety of them are prescribing inappropriately.
‘Some sufferers will profit from it but it surely’s a mistake to encourage each man to have testosterone testing.
‘I’m not anti-TRT however encouraging males to assume there’s a easy remedy on the market that in lots of instances could haven’t any impact just isn’t proper. When you have low testosterone however no signs, you’re virtually actually not going to learn from therapy.’
He says a part of the issue is that low testosterone is ‘a spectrum’ — not only a quantity on a blood check outcome.
‘When you have beneath 8 nmol/l you’re unequivocally low in testosterone. Above 12, you’re positively okay.
‘However between these two numbers you could be both — some males fortunately go round feeling wonderful with readings of 8.5 or 9. The blood check is merely a brick within the wall of constructing an correct prognosis.’
He provides: ‘Males every want barely completely different pure ranges of testosterone — and there’s no proof that males with the best ranges of testosterone are any more healthy than males with decrease regular ranges.’
Dr Jayasena provides that, 20 years in the past, TRT was largely reserved for males with an plain scientific want, comparable to those that had misplaced a testicle to most cancers.
‘Now it’s largely simply males who’re older, much less wholesome or overweight. But for a lot of it’ll make no distinction. It’s like having an outdated automotive and placing shiny new wheels on it — there are nonetheless a lot of different issues that may go unsuitable.’
Based on the NHS, the time period male menopause is ‘unhelpful’ because it implies that males endure signs comparable to despair and waning libido on account of a sudden drop in testosterone in center age, simply as girls do with oestrogen.
It provides: ‘This isn’t true — in lots of instances the signs are nothing to do with hormones however brought on by poor eating regimen, lack of train, extra alcohol consumption or low shallowness.’
In the meantime, the American Faculty of Physicians — having scrutinised the proof for and towards TRT in older males — dominated it ought to solely be prescribed as a pick-me-up for sexual perform. For every little thing else, it says, there’s inadequate proof.
However David is satisfied that taking testosterone gave him again his life.
When it was first examined, his studying was simply 6.9 nmol/l. After he started having injections in autumn 2021, his power ranges, intercourse drive and muscle power all bounced again to regular inside weeks. He has even been capable of come off his antidepressants.
‘I felt quite a bit stronger and will raise extra weights on the fitness center,’ he says. ‘The night time sweats disappeared and my libido was restored to its wholesome degree. With out that blood check, it will by no means have crossed my thoughts that every one these issues could possibly be right down to an absence of testosterone.’
