Scientists at Birmingham University have developed an over-the-counter male fertility test, which they say may cut the wait for fertility treatment for couples by up to 12 months. The test is available on the market now.
Samples from 150 men show the test gives 95 per cent accuracy. Most couples in the UK are advised to wait a year before seeking advice from a doctor, but the test provides necessary information at the early stage of trying.
The 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 fertilise an egg.
