Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The objective is to study the effects of bicycle riding and bicycle seats on blood flow to a man's reproductive organs. It has been shown that bicycle riding can affect a man's ability to have an erection. Each year, newer and better bicycle seats come out but these seats have not been adequately studied for their effects on blood flow in the genital region.
