There’s a rising temper of jubilance in England and for good purpose – on 19 July the UK will press forward and take away all remaining coronavirus restrictions. The vaccine marketing campaign has severely weakened the hyperlink between transmission and hospitalisation, at the same time as lethal new variants such because the Delta variant have entered our shores. Nonetheless, the vaccines aren’t a silver-bullet – the virus can nonetheless breach the immune system’s defences. In the meantime, new analysis has recognized a significant threat consider males.
Men with symptomatic COVID-19, who had been discovered to have low testosterone following admittance to hospital, had been extra more likely to turn out to be severely unwell and die from the illness, new analysis has discovered.
The research, carried out in Milan in the course of the first wave of coronavirus in 2020, discovered that the decrease the degrees of testosterone, the upper the probability that male sufferers would wish intensive care, be intubated on a ventilator and stay in hospital over an extended interval.
Their probability of dying elevated six-fold.
Professor Andrea Salonia and his colleagues on the San Raffaele College Hospital in Milan in contrast 286 male Covid sufferers, who got here to the emergency division, with 305 wholesome male volunteers, who attended hospital to provide blood between Feb and Might 2020.

These sufferers who had delicate signs or had been admitted to hospital had barely larger testosterone ranges (between 3-4 nmol/l) than these admitted to ICU or those that died of the illness (simply 0.7-1.0 nmol/l).
Even when age, pre-existing situations and physique mass index (BMI) – the universally recognised measure of wholesome weight – had been taken under consideration, the variations in hormonal profiles and medical outcomes had been nonetheless stark.
Commenting on the findings, Professor Salonia, a specialist in urology and endocrinology at San Raffaele Hospital, stated: “At the start of the Covid pandemic, we were seeing far more men than women coming to hospital and suffering very severe forms of the disease. We immediately thought this might be related to male hormone levels, particularly testosterone.
“But we never expected to see such a high proportion of Covid patients with these extremely low levels of testosterone, in comparison to a similar group of healthy men.”
Prof Salonia added: “The relationship is very clear: the lower the testosterone, the higher the severity of the condition and likelihood of death. I’ve never seen anything like it in my 25 years in the field.”
As a result of the crew doesn’t have knowledge on the testosterone ranges within the sufferers earlier than they contracted COVID-19, they can not say whether or not low testosterone was a pre-existing long-term situation that exacerbated the illness or whether or not it was attributable to the SARS-COV2 virus (the virus that causes COVID-19).
Nonetheless, different analysis has proven that some receptors for the virus, together with the enzyme TMPRSS2, are linked to male hormones and that the virus reduces the variety of Leydig cells within the physique, which produce testosterone.
“We simply don’t have the data to know which came first in these patients, the low testosterone levels or the Covid,” defined Professor Salonia.
“Testosterone does play a role in protecting men from disease. However, it’s also possible that the virus itself is able to induce an acute reduction in testosterone levels, which then predisposes these men to a worse outcome. We’re now following up these patients over a longer time period, to see how their hormone levels change over time, so we can try and answer these questions.”
Professor Jens Sonksen, an government member of the EAU (Europe’s largest urology convention), stated: “The SARS-CoV-2 pandemic has had a tremendous impact on global health since the virus first started spreading in early 2020. We have learned a lot about the virus and possible health consequences from COVID-19 since those early days, but there is much still to learn.
“This is highlighted by this new research, which found a surprisingly low level of total testosterone in men with COVID-19 compared to healthy controls.
“Symptomatic COVID-19 patients with low testosterone were also more likely to become critically ill from COVID-19. Additional research on potential impacts from COVID-19 on men’s health is definitely needed.”
Low testosterone ranges – find out how to inform
The American Urology Affiliation (AUA) identifies low blood testosterone signs as the next:
- Low intercourse drive
- Diminished lean muscle mass
- Erectile dysfunction
The well being physique provides: “There are many other possible reasons for these symptoms, such as: opioid use, some congenital conditions (medical conditions you are born with), loss of or harm to the testicles, diabetes, and obesity (being overweight). See your doctor if you have any of these symptoms.”
