The mounting research regarding the use of PRP for the improvement of fertility in men has been mounting, but there have been no studies regarding the use of PRP for the restoration of size in the testicle. When men take testosterone replacement therapy, and sometime with age, there can be a resulting atrophy of the testicles with a decrease in both size and sperm count.

We will be conducting an IRB-approved clinical trial to evaluate this idea.

If you are interested in participating in this study or in following the results thereof, please tell us how to stay in contact…
