More than 45 million couples worldwide are affected by infertility, and more than 40 per cent of these are partly because of male infertility, according to the Boston-based research team.
Despite the prevalence of male fertility being almost equal to their female counterparts, the access to male testing is seriously limited.
This is due to a number of factors including social stigma surrounding the process and high costs of microscope-based testing and computer analysis.
This new app, which was designed for android but could be adapted for iPhone if approved by the US Food And Drug Administration, is the only at-home testing product of its kind.
Men are required to put their semen sample on a disposable microchip, which is then inserted into an optical attachment that plugs into your smartphone.

The research claims that it can provide the user with a 98 per cent accurate reading, based on World Health Organisation guidelines, accuracy levels similar to that of computer-assisted laboratory analysis.
The smartphone-based semen analyzer may also be used for home-based monitoring of men who undergo vasectomy.
