It basically speeds Iodine into the testicles & into the prostate far faster than taking Iodine orally. We found results surprisingly fast that include improved ejaculate, enhanced sensitivity to the glans and improved prostate function. Young men would not see any improvement, but older men like myself (I'm 69) need help. I like the T2T procedure so much that I do it every night. The carrier oil is required to prevent stinging the scrotum and to prevent possible dermatitis to the scrotum.
Also here is my Iodine Research File to share with friends & family. It has the very best doctor reports organized by subject, and it even include T2T in the Prostate Chapter. http://tinyurl.com/iodine-references
