New OTC fertility tests in development
New OTC fertility tests in development
NEW “his and her” fertility tests should be on sale in the United Kingdom next year. The test kit, known as Fertell, has been developed by researchers from the University of Birmingham and medical devices company Genosis.
Presenting details of the male test at the European Society of Human Reproduction and Embryology meeting in Lausanne, Switzerland, on July 2, Professor Christopher Barratt of the University of Birmingham said: “[The test] takes an established technology that is usually employed in the laboratory and embodies the know-how into a simple to use format for the lay person.”
The male test measures the concentration of motile sperm in the semen. After sperm are deposited into a container, a button is pressed which releases a column of artificial cervical mucus heated to 37C, reproducing the conditions in a woman’s body. Only motile sperm are able to swim through the mucus column to a point where they are collected and tagged with gold-labelled antibodies. They can then be detected on a nitro-cellulose strip and, if sufficient numbers are present, a red line will be produced. The number needed to produce such a result will be greater than 10 million motile sperm per ml (equivalent to the World Health Organization guideline for normality).
“The current screen for infertility is to try for 12 months and then seek medical advice. But 40 per cent of cases of infertility are due to male factors and this test can indicate early on if there is potentially a problem with the man,” Professor Barratt commented.
