Aetna considers the implantable vas deferens ligation clip (Vasclip, VMBC, LLC, Roseville, MN) experimental and investigational for ligation of the vas deferens for male sterilization because there is insufficient evidence in the peer-reviewed literature that the Vasclip procedure provides clinically significant benefits over standard vasectomy procedures.

Vic’s Notes: Men don’t report pain at the same rates as women do.
- Post-vasectomy pain, an underestimated side-effect
Vic’s Notes: This is a good example of a misquoted study. Sometimes you’ll see a reference to study of 700,000 men in the Netherlands. That never actually happened.

Sterilization of men and women is the most popular method of contraception in Canada. The contraceptive effect of a vasectomy usually occurs within 3 months. The production of sperm, however, is not interrupted, and an increase in pressure proximal to the ligation site may cause rupture of the epididymis or the ductus deferens, with extravasation of spermatozoa and the formation of granulomas or sperm antibodies. Increased pressure may also explain the postvasectomy pain syndrome.
- New AUA Statement as of Nov 2012.Chronic scrotal pain associated with negative impact on quality of life occurs after vasectomy in about 1-2% of men. Few of these men require additional surgery.
