An IUD For The Boys
Ob.Gyn.News has a quick review of promising male birth control methods. Check out #3, the IVD (Intra Vas Device):
1. Reversible inhibition of sperm under guidance (RISUG). This method of male contraception involves vas deferens injections of styrene maleic anhydride in the solvent dimethyl sulfoxide.
2. Adjudin (also called AF-2364). This is an analogue of an old anticancer drug called lonidamine that is conjugated to follicle-stimulating hormone (FSH).
3. The Intra Vas Device (IVD). This device is composed of a set of two flexible silicon plugs, 1 inch long and either 1.2 mm or 1.4 mm in diameter. The plugs are inserted in the vas deferens, separated by a small space, and they physically block the passage of sperm. After they have been inserted, the patient can neither feel nor palpate the device.
The no-scalpel procedure can be performed by anyone experienced in vasectomy. It is expected to cost about $1,000, which is comparable to a vasectomy. Unlike a vasectomy, however, reversal would theoretically be much simpler and much less expensive—about another $1,000, compared with $5,000-$12,000 for a vasovasostomy.
In May 2006, the Food and Drug Administation (sic) approved human trials with this device, and if all goes according to plan, approval is expected in Europe, Canada, and the United States by 2010.
4. Suppression of spermatogenesis with transdermal testosterone gels plus various progestins.
