Sex hormone therapy can reverse ageing process
London: A new study has supported the testosterone treatment that is being used by pop star Robbie Williams.
According to the study, the testosterone treatment can really help reverse the ageing process in men.
The chart-topping singer, 37, had admitted injecting himself with the sex hormone twice a week in a bid to boost his sex drive and slow down the march of time.
Loss of muscle tissue, which is a typical symptom of ageing and is also associated with diseases such as aids and cancer, can be treated using anabolic steroids but these can have unwanted side-effects, making testosterone replacement a healthy alternative.
The new research shows that nine proteins in the blood alter with age.
However, the profile of some of these proteins can be reversed by testosterone treatment, and prevent the loss of muscle mass.
Researchers from Boston University School of Medicine and University of Texas Medical Branch in the United States compared protein levels in serum samples from two groups of healthy men.
“It seems that testosterone replacement does not necessarily mean a restoration of full testosterone functionality for the older man,” quoted the researchers as saying.
Testosterone treatment increased lean muscle mass and levels of the appetite suppressing hormone leptin, for both groups of men.
The hormone also increased levels of pro-collagen and growth protein IGF-1 in young men and the researchers saw a similar increase in a small group of older men.
Dr.Monty Montano said: “The blood proteins we found that altered with healthy ageing also have links to maintenance of muscle, such as IGF-1 and pro-collagen, or are involved in regulation of the immune system, possibly reducing T-cell and neutrophil responses with age.
“Additionally all of the proteins we found are involved with the signalling pathways controlled by proteins which are known to be associated with ageing.
“It is no simple matter to find a one size fits all test for ageing. Our results suggest that there is a difference in response to anabolic steroids between young and older men, despite both groups increasing in muscle mass,” added Montano.
The study has been published in BioMed Central’s open access journal Immunity and Ageing.
