The BBC news reports today that
The world's first over-the-counter home fertility test for men has been developed by scientists at Birmingham UniversityThe test takes an hour, and forces the sample sperm to swim through a mock female cervix. Dependent on how many sperm get through the barrier, the test measures whether or not the male has enough sperm to fertilize an egg
First of all I must say that a similar test is available in the US. Second as far as I am concerned (until clinical studies prove otherwise) all this test does for a man is to confirm whether or not he has any sperm at all. Obviously that is good to know but let me reemphasize that all one will be able to tell by taking the test is that one is not completely infertile not how fertile one is .
