How often should I use this, and how long does it take to see improvements?

Hi! Use The Underdog throughout your day whenever sitting for longer than 15-20 minutes (temperature danger zone). e.g. when driving, sitting at work, and relaxing at home. Sperm take roughly 2 ½ to 3 months to fully mature. So any healthy lifestyle changes including using The Underdog may take this long to show up in improvements to sperm count or quality. We'd love if you visited our blog for more tips to improve your swimmers.

Can this be used when riding bicycle?

Its pretty small and compact. I'm not 100% sure, but I would say yes.
