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.
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,
- healthy male with normal physical findings
- normal testicular volume (15-30mL)
- detectable sperm in ejaculates
- Men with past history of
- significant cardiovascular
- thromboembolic disorders
- renal (including undiagnosed urinary tract bleeding)
- hepatic, prostatic and testicular disease
- prior vasectomy or scrotal surgery
- Men with a past history of drug abuse will also be excluded.
