Nov. 11, 2004 | WASHINGTON (AP) -- The world of male contraception has been limited to condoms and vasectomies. But researchers now point to a new method that shows promise -- a shot that prompts an immune reaction to a protein produced in the male reproductive system. The method worked in experiments on male monkeys, most [ed: MOST?!] of which regained their fertility when the treatments were stopped, researchers report in Thursday's issue of the journal Science. "Immunocontraception for males is a possibility and hopefully will be developed for human use over the next several years," said Dr. Michael O'Rand of the University of North Carolina.
How does this work, you ask?
"We don't understand the exact mechanism yet, but we think the immunocontraception works by preventing the sperm from freeing itself from the seminal fluid to make its way to the uterus and oviducts to fertilize the egg," O'Rand said.
That is code for, "I don't know but it would be pretty fucking cool, even though it really just makes you sterile!" Men, don't get your vas deference in a bundle. This could be awhile.
