in in­fer­til­ity cases across the world has of­ten been linked to chem­i­cals used in ev­ery­day items such as tex­tiles, drugs, food and per­sonal-care prod­ucts. But ef­forts to reg­u­late the use of such chem­i­cals, which dis­rupt the func­tion­ing of the en­docrine gland, are ham­pered by lack of test to prove their dele­te­ri­ous ef­fects. A new test shows that many of the chem­i­cals ad­versely af­fect CatSper ion chan­nel, a cal­cium chan­nel in the sperm which con­trols its motil­ity. En­docrine dis­rupters open CatSper, in­crease cal­cium lev­els in sperms and change their swim­ming be­hav­iour. EMBOre­ports, May12
