A
recent study that investigated supplements and their potential impact on
testicular cancer has made its rounds in the media. Needless to say, gym bros
all across the world are fearing for their family jewels. But, should you
worry? Well, not necessarily and here’s why.
The
authors of the study investigated the relationship between testicular cancer
and muscle building supplements. Male residents from hospitals located in
either Massachusetts or Connecticut during 2006-2010 were recruited for the
study. Some of the men already had some degree of testicular germ cell cancer —
a common form of cancer in young men. Others did not.
The
men were provided with a questionnaire which asked about their supplement use.
Supplement use was classified as using one or more supplements one or more
times a week for four consecutive weeks. The researchers assessed 30 different
muscle building powders and pills but only noted creatine, protein and
androstenedione. Additional questions were asked related to exercise habits,
smoking, drinking, and family history related to testicular cancer.
After
analyzing the data and taking into account the different risk factors for
testicular cancer, the researchers found that men who used workout supplements
had a 65 percent greater risk for developing testicular cancer than those who
did not.
Does
that mean you should burn all your workout supplements? Of course not.
This
study only found that using workout supplements is potentially connected to an
increase in testicular cancer. It does not prove a relationship. Additionally,
because the category of muscle building supplements were too broad, no specific
recommendations can be made on which to avoid. Therefore, there is currently no
reason to fear the protein or creatine powder in your cabinet.
However,
the quality of the dietary supplement industry is questionable at times. It is
always a good idea to consult with a registered dietitian to assess any dangers
of a supplement you are taking.
