Bisphenol-A (BPA), known as the "gender bending" chemical because of its connection to male impotence, has now been shown to decrease sperm mobility and quality.
The findings are likely to increase pressure on governments around the world to follow Canada and ban the substance from our shelves.
BPA is used widely to make plastic harder and watertight tin cans.
It is found in most food and drink cans – including tins of infant formula milk – plastic food containers, and the casings of mobile phones, and other electronic goods.
It is also used in baby bottles though this is slowly being phased out.
BPA has been the subject of intense research as it is a known endocrine disrupter which in large quantities interferes with the release of hormones.
Earlier studies have linked it to low sex drive, impotence and DNA damage in sperm.
