Glow, an app for tracking a woman's reproductive health, has expanded out to tracking the state of male reproductive health as well.
This app, available for iPhone and Android, lets men know how their lifestyle choices are affecting their swimmers, factors such as drinking, smoking, masturbating and exercising could all play a part in healthy semen, the Daily Star reported.
For example, Glow suggests that hopeful dads might want to ditch the lube for sex because the chemicals can be toxic to their seed.
The San Francisco-based business would collect the data logged by users in a bid to analyse male fertility on a wide scale.
