Here ya go.... The Pill for Men by Organon....
Researchers at Edinburgh University's Centre for Reproductive Biology have finally found a way to suppress daily sperm production while maintaining normal testosterone levels. This was not an easy task given that men emit millions of sperm in each ejaculation, while women only produce one egg per month.
From the results of these studies, Organon, a pharmaceutical company in the Netherlands, has developed a pill that is set to go on the market by 2005. The pill has proven to be 100% effective in preliminary clinical trials.
A larger study, involving 120 men between the ages of 18 and 45 from Europe and the United States, is currently underway. The participants have tiny rods implanted under the skin of their arm that deliver a form of progestogen (commonly found in the female birth control pill) to block sperm production.
In order to maintain their sex drive and their "male characteristics," the men receive testosterone replacement therapy injections every four to six weeks over the course of the yearlong study. The results should be available by the end of 2002.
The results of a smaller study conducted in the year 2000 using similar methods showed a completely reversible blockage of sperm production in all 66 participants.

How does it work?
The pill contains desogestrel, a synthetic hormone that is the main component in the female pill, as well as the male hormone testosterone. This combination blocks the production of sperm while maintaining male characteristics and sex drive. As with the female contraceptive pill, it must be taken daily.
In terms of effectiveness, the male pill seems to be the best. In clinical trials, all of the participants' sperm counts dropped to zero, which means that the male pill would be more effective than the condom and even the female pill.
According to the Food and Drug Administration (FDA), the condom has a failure rate of about 14% under typical conditions, while the failure rate of the female pill is less than 1%. Although the male pill has been proven 100% effective so far, the results of the current clinical trial are necessary before any definite conclusions can be drawn.
