A team of British scientists introduced a contaceptive vaccine for men that is believed to be more efficient than the pills for women. It’s effects can last up to 2 years according to the Daily Mail.
The contaceptive methods used for men haven’t changed for centuries and are limited to condoms and vasectomy. This vaccine may be the next best thing, it blocks the movement of the spermatozoids. Unlike it’s predecessor it isn’t hormonal and side effects like depression and muscle pain are avoided.
The vaccine blocks the canal, that connects the testicles and utherea, with gel. The vaccine has been tested on monkeys and it’ s 100% effective. Human trials are starting next year.
