I am a female, and am right handed. I don't get why my left armpit gets smellier than my right! Why would this be? Ive always heard it can be smellier due to hormones, etc.. Please help! Lol Thanks

Hey Brittney, thanks for your question. The simple answer is a difference in bacteria (or bacterial balance) between left and right. About half of the people we have screened had (small) bacterial differences between left and right armpit. Hormones can have a certain influence, although this is rather small, to my opinion. It is often the dominant arm that can have more odor (maybe due to more blood circulation and more sweat production?), but this is definitely not always the case. Best, Chris
