Millions of men find hope in testosterone supplements to normalize their testosterone levels and ultimately improve their sexual drive. However, there is no conclusive study on the effect of such therapy when used by healthy men experiencing low testosterone level.

To some, testosterone improves the quality of their lives. Those taking Spartagen testosterone supplement for instance claimed that they feel rejuvenated after taking this product.

A result of a landmark study on testosterone treatment was published in The New England Journal of Medicine showing such treatment provide modest benefits on men’s sexual functioning. “This was referred as a landmark study since it offers the initial credible data on the effects of testosterone on some health issues it wishes to resolve”, Dr. Eric S Orwoll of Oregon Health and Science University said.

Though some doctors desire for positive results of testosterone treatments, Dr. Sundeep Khosla from Mayo Clinic College of Medicine expressed his sentiments when he said; “Testosterone treatment has been abused by doctors who prescribe such treatment to patients without even checking their testosterone levels first”.  Dr. Orwoll shared the same concern when he said; “There has been so many prescribing out there and this does not seem to have any significant effect on any average man”.

Another study was conducted in Perelman School of Medicine in the University of Pennsylvania where 790 men of 65 years old and above were used as subjects. Since testosterone is lowered as man ages, these men are expected to share the same testosterone issue. Many of them complain low sexual drive, walk slower than they use to and complained for low zest in life. They were given testosterone treatment to resolve their health issues.  The result of the study showed that their testosterone level increased, many of them reported improved sexual drive and slight mood improvement. However, there was no effect on their walking speed.

But critics of testosterone therapy question the possible health hazards that go along with such treatment like heart disease and prostate cancer. In response to this, FDA urged manufacturers of such treatment to conduct further research to establish factual data whether these treatments will cause problems on the user’s future health as well.

Dr. Joel Finkelstein of Harvard expressed his worries on testosterone’s lack of data as well as its long term risk, considering the fact that many men are taking these supplements without complete knowledge about their long term effects. Hence, Dr. Finkelstein said that large clinical trial on testosterone treatment has to go forward.
