'Are You Using Anything?'

In ancient China, women drank lead and mercury as a form of birth control; during the Middle Ages in Europe, women wore amulets of herbs, animal parts and material soaked in potions to prevent pregnancy. Whether science-based or superstitious, family planning has been practiced since our species understood how babies were conceived.

When the Pill came onto the market in the 1960s, birth control was revolutionized. Since then, a variety of contraceptives -- from patches to pills, from injections to insertions -- are continuously improved and made available to women all over the world.

As contraceptive research continues, more effective forms of birth control -- without the negative side effects -- are being tested. The latest is a simple injection that can make the recipient infertile for six to 15 years, depending on the user's needs. It's non-hormonal, so there's no worry about weight gain, mood swings, losing libido or long-term effects such as cancer, blood clots or high blood pressure. Early testing shows it's reversible, if conception is desired. The most controversial aspect of this birth control? It's for men.

What's more, even though it's considered one of the safest, most effective forms of contraception available, most men will never have access to it -- including American men.

The injection is called Reversible Inhibition of Sperm Under Guidance (RISUG, pronounced RICE-ugh). It was developed by professor Sujoy K. Guha, an Indian researcher of biomedical engineering at the Indian Institute of Technology. Guha has tested RISUG on men for more than 25 years with successful results. His research has drawn praise from the World Health Organization, as well as doctors from around the world. Pharmaceutical companies in India and Egypt are vying to buy RISUG, and, if all continues well with Guha's research, RISUG will be available on the Indian market sometime within the next few years.

"RISUG is the most effective and advanced technology we've had in 40 years," says Ronald Weiss, an assistant professor of medicine at the University of Ottawa, Canada. Weiss focuses his family practice on male health and has traveled to India to see the research on RISUG for himself. RISUG is an injection of two chemicals into the vas deferens, the place where sperm leaves the testicles. The whole procedure is less invasive, causes fewer complications and promises to be easily reversible as compared with vasectomy or rubber plug devices (other currently used methods of male contraception).

The entire procedure is virtually painless and becomes effective within one hour of injection. There are no known side effects, aside from slight swelling immediately after the injection. Guha reports some of his test subjects were sexually active on the same day they received the injection. None of the men who has tested RISUG has gotten a woman pregnant.

"We applied three or four years ago to do a clinical trial [in Canada]," says Weiss. "But it will never be approved. The [RISUG] studies that have been done to date have fallen short -- it's not to say the studies weren't good or aren't useful, but they don't meet the criteria for Western acceptance."

So why can't the studies be completed in Canada or the United States in order to test RISUG by Western standards?

"In order to obtain approval to study RISUG, we need to duplicate a number of the studies and that means you need money," Weiss says. "That either comes from a benevolent rich person, which is hard to come by, or a pharmaceutical company."

Herein lies the problem: RISUG may be too effective. Pharmaceutical companies are pouring millions into research on male contraceptives, particularly the male version of the pill, but none is interested in RISUG.

"What does a hormonal contraceptive [like the Pill] represent to a pharmaceutical company?" Weiss asks. "Recurrent sales. It's like women's birth control. They sell it over and over and over again. They want something they can make an ongoing profit from. Business is business."
