ClinicalTrials.gov Identifier:	NCT00663533

Purpose

The purpose of this research study is to study an experimental vasectomy device called the Vas-X. This is an experimental study of this new approach to vasectomy.

Primary Outcome Measures:

absence of sperm in ejaculated semen 6 months after vasectomy [ Time Frame: 6-months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

any side effects as well as degree of occlusion of the resected segment of vas deferens [ Time Frame: 6-months ] [ Designated as safety issue: Yes ]

Enrollment:	10
Study Start Date:	April 2008
Estimated Study Completion Date:	January 2015
Primary Completion Date:	July 2009 (Final data collection date for primary outcome measure)

Intervention Details:

mechanical vasectomy device

Detailed Description:

The Vas-X works by stripping the lining of the vas deferens, the tube that sperm pass through during ejaculation. It is used in a way very similar to routine vasectomy, however, in a routine vasectomy, the vas is burned with an electrical device. With the Vas-X, there is no burning. The investigators are testing the Vas-X to determine whether it will offer a better way of performing a vasectomy.

The investigators will conduct this study at the University of Washington Medical Center, Seattle.
