Men with symptomatic COVID-19, who’ve low testosterone following hospitalization, have been extra more likely to develop extreme an infection and die from the illness, suggests a brand new examine.
The examine, carried out in Milan through the first wave of the pandemic in 2020, revealed that the decrease the degrees of testosterone, the upper the probability that male sufferers would want 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 from the San Raffaele University Hospital in Italy in contrast 286 male Covid sufferers, who have been admitted to the emergency room, with 305 wholesome male volunteers, who went to the hospital to present blood between Feb and May 2020.
The staff checked each sufferers and volunteers for ranges of male hormones, together with testosterone.
Testosterone is measured in nanomoles per litre (nmol/l) and 9.2 or under is deemed the brink for low testosterone, termed hypogonadism.
Nearly 90 per cent of the sufferers had testosterone under this degree, in comparison with simply 17 per cent of the wholesome volunteers.
Furthermore, testosterone ranges within the sufferers have been additionally considerably under the brink, averaging round 2.5 nmol/l.
Those sufferers who had delicate signs or have 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 – have been taken under consideration, the variations in hormonal profiles and scientific outcomes have been nonetheless stark.
Commenting on the findings, Professor Salonia, a specialist in urology and endocrinology at San Raffaele Hospital, stated:
Prof Salonia added:
Because the staff doesn’t have information on the testosterone ranges within the sufferers earlier than they contracted COVID-19, they can’t say whether or not low testosterone was a pre-existing long-term situation that exacerbated the illness or whether or not it was brought on by the SARS-COV2 virus (the virus that causes COVID-19).
However, 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.
Professor Jens Sonksen, an government member of the EAU (Europe’s greatest urology convention), stated:
The American Urology Association (AUA) identifies low blood testosterone signs as the next:
- Low intercourse drive
- Reduced lean muscle mass
- Erectile dysfunction
