The first home test kit for male fertility has been developed by American scientist Dr Ronald Ericsson. The kit will help overcome the emotional and practical problems associated with conventional male fertility testing by allowing both speed and privacy. And by establishing fertility in the male first, thousands of women may avoid unnecessary examinations. The test works by exploiting the fact that sperm use up oxygen when they swim. The reduction in oxygen changes the colour of an indicator dye from purple to pink. If there are no motile sperm, oxygen is not used up and the dye retains its original purple colour. the kit will be available across chemist' counters throughout Europe from the end of February.
